HOW TO MAKE A SIMPLE ELECTRIC MOTOR

2024-03-02T22:16:00.000-08:00

You can make a simple motor from a few items you probably already have in your home.

Take two large-eyed needles and sellotape them to the terminals of a battery. Also tape the battery down on a table:

Take some insulated wire, about a foot long, and wrap it around a thick pen as many times as you can, then remove it from the pen. Wrap the wire around the coil each side a few times to hold the wire together. Leave enough wire sticking out each side to reach the eyes of the needles.

Now, with a scalpel, remove one side of the insulation from both ends of the wire – just enough to ensure that the needles' eyes will make contact with the copper wire.

In profile, this would look like this:

Thread the two ends into the two large eyes of the needles.

Now tape a magnet to the side of the battery, either north or south pole facing upwards.

Now, if you start to spin the coil you will find it continues to spin. (The coil will only spin one way so if you start to spin it and nothing happens, spin it the other way.)

Why do we only cut half the wire?

Let's take one configuration of the coil and simplify it as below:

If we used Fleming's left-hand rule, the motion above would be that the bottom half of the coil moves away from us.

When the coil spins 180° (one half-turn) the force on the wire would be towards us.

The coil would stop.

A way to prevent this is to stop the current (electricity won't pass through the insulation) and no forces will operate on the coil for one half-turn. What gets the coil around the non-powered half of the turn is momentum.

Differences Between Electric Motors and Generators

2024-03-02T22:10:00.000-08:00

Electric motors and generators have significant differences in terms of function and what they are used for, but both are closely connected to Faraday's Law of Electromagnetic Induction.

Once an experimental novelty, electricity is now an utterly indispensable part of modern life. Electricity provides lighting, climate control, entertainment, and more. To provide electrical power, energy is converted from other forms into electricity, powering the systems and devices people tend to take for granted.

Converting energy from one form to another is the key to understanding the differences between electric motors and generators. An electric motor converts electricity into mechanical energy, providing a power source for machinery. A generator does the opposite of this, converting mechanical energy into electricity.

Despite this significant difference in function, electric motors and electric generators are closely connected by their underlying mechanisms and fundamental structure. Both rely on an important law of physics: Faraday’s Law of Electromagnetic Induction.

Faraday’s Law of Electromagnetic Induction: Electricity and magnetism

Today, it’s well known that electricity and magnetism are two manifestations of a single fundamental force, called electromagnetism. Central to the universe as we know it, the electromagnetic force is thought to have existed in its current form since somewhere between 1012 and 106 seconds after the Big Bang.

In 1831, physicist Michael Faraday discovered electromagnetic induction, revealing the intimate relationship between the observed phenomena of magnetism and electricity. Interestingly, in 1832, another researcher, Joseph Henry, discovered it independently. Faraday was the first to publish his findings, and to this day, he is credited with the discovery. Later, James Clerk Maxwell would discover a way to formulate Faraday’s findings mathematically, leading to the development of the Maxwell-Faraday equation.

Faraday’s Law of Induction is a law of physics designed to accurately predict and measure how a magnetic field will interact with an electric circuit to produce an electromotive force (EMF). EMFs convert other forms of energy, such as mechanical energy, into electrical energy. This law of physics is what allows us to create both electric motors and electric generators. Although these two types of machinery perform opposite functions, they both rely on the same underlying laws of physics.

Electric generators: Converting mechanical energy into electric energy

According to Faraday’s Law of Induction, whenever there is a change in the magnetic field across a conductor, such as a wire coil, electrons are forced to move perpendicular to that magnetic field. This generates electromotive force, which creates a flow of electrons in one direction. This phenomenon can be used to produce electricity in an electric generator.

To create this magnetic flux, the magnets and the conductor are moved relative to one another. The wires are wound into tight coils, increasing the number of wires and the resulting electromotive force. Continuously rotating either the coil or the magnet, while keeping the other in place, gives continual flux variation. The rotating component is referred to as a “rotor,” while the stationary component is called a “stator.”

Electric generators fall into two broad categories: “dynamos,” which generate direct current, and “alternators,” which generate alternating current.

The dynamo was the first form of electric generator that was useful for industrial applications. During the Industrial Revolution, it was invented independently by several people. The electric dynamo uses rotating coils of wire and magnetic fields to convert mechanical energy into direct current (DC). Historically, dynamos were used for electric power generation, often using steam as a source to generate the needed mechanical energy.

Today, the electric dynamo has few uses outside of a few low-power applications. Alternators are far more widespread for electricity generation. This type of generator converts mechanical energy into alternating current. A rotating magnet serves as the rotor, turning within a set of conductor coils on an iron core, which serves as the stator. As the magnetic field rotates, it generates an ac voltage in the stator. The magnetic field can be created either by permanent magnets or by a field coil electromagnet.

An automobile’s alternator, as well as central power stations that provide electricity to a grid, are electric generators.

Electric motors: From electrical energy to mechanical energy

An electric motor does the opposite of an electric generator. Instead of turning mechanical energy into electricity, an electric motor takes electricity and converts it into mechanical energy. Electric motors can be found in a diverse range of applications, from industrial manufacturing machinery to everyday household appliances. The rotor turns a shaft to create mechanical power. The stator is made from coil windings or permanent magnets, with a core of thin sheets layered together. Known as laminations, these layers create less energy loss than a solid core. Between the rotor and stator is a small air gap, which helps increase the magnetizing current.

Although electric motors can be piezoelectric, electrostatic, or magnetic, the vast majority of modern motors use magnets. Some are designed to run on dc, while others use ac. You can find electric motors of all sizes in an impressively wide range of applications. From tiny motors in battery-powered watches to massive electric motors that power industrial manufacturing machinery, this robust yet elegant piece of technology is central to modern life as we know it.

How Faraday’s Law changed the world of electrodynamics

Although electric motors and electric generators perform opposite functions, they both rely on the same underlying physical principle: Faraday’s Law of Induction. During the early 19th century, Michael Faraday’s contributions to the study of electricity and magnetism were unparalleled. Despite having little formal education, and despite the fact that the empirical study of physical phenomena was a relatively new field of knowledge, Faraday is without a doubt one of the most influential scientists in all of human history.

Faraday’s monumental discovery—that magnetic fields interact with electric currents to create an electromotive force —opened the door to modern electric technology. Faraday’s law of induction is the principle behind transformers, electric motors, electric generators, inductors, and solenoids. Without this knowledge, it would have been impossible to develop the reliable equipment that generates electricity to the grid or electric motors to power other machinery. In fact, the electrodynamics developed by Faraday and later Maxwell were also a major catalyst for Albert Einstein’s Theory of Special Relativity.

Electric motors and electric generators are quite distinct from one another in their respective functions. However, in terms of physics, they exemplify two sides of the same coin. Both rely on the same underlying physical principles, and understanding those principles has been instrumental in the development of even the most commonplace modern technology.

What does an electrical engineer do?

2020-09-02T00:27:00.001-07:00

What is an Electrical Engineer?

Electrical engineering dates back to the late 19th century, and is one of the newer branches of engineering. The field of electronics was born with the invention of the thermionic valve diode vacuum tube in 1904 by John Ambrose Fleming, and was the foundation of all electronics, including radios, television and radar, until the mid-20th century.

Electrical engineering is concerned with the technology of electricity and specifically deals with electricity, electro-magnetism and electronics. It also covers power, control systems, telecommunications and signal processing.

An electrical engineer is someone who applies the physics and mathematics of electricity, electromagnetism and electronics to design and develop new electrical equipment and systems, to solve problems and to test equipment. The emergence of the modern age is noted by the introduction of electricity to homes, businesses and industry, all of which were made possible by electrical engineers.

Some of the most important pioneers in electrical engineering include Thomas Edison (electric light bulb), George Westinghouse (alternating current), Nikola Tesla (induction motor), Guglielmo Marconi (radio) and Philo T. Farnsworth (television). Innovative ideas and concepts were turned into practical devices and systems that paved the way to what we have and use today.

Present-day electrical engineers work on various projects, from designing household appliances to designing large-scale electrical telecommunication systems, electrical power stations and satellite communications systems.

What does an Electrical Engineer do?

Electrical engineers work on a variety of projects, such as computers, robots, cell phones, cards, radars, navigation systems, wiring and lighting in buildings and other kinds of electrical systems. More and more, electrical engineers are relying on computer-aided design (CAD) systems for the creation of schematics and to lay out circuits, and they use computers to simulate how electrical devices and systems will function.

Electrical engineers work in various industries and the skills required also vary. These skills can range from basic circuit theory to those required to be a project manager. The tools and equipment that an electrical engineer may need are also variable, and can range from a straightforward voltmeter to a top end analyzer to advanced design and manufacturing software.

An electrical engineer's job duties may require:

Evaluating electrical systems, products, components, and applications
Designing and conducting research programs
Applying knowledge of electricity and materials
Confirming system's and components' capabilities by designing testing methods and properties
Developing electrical products by studying customer requirements
Researching and testing manufacturing and assembly methods and materials
Developing manufacturing processes by designing and modifying equipment
Assuring product quality by designing electrical testing methods
Testing finished products and system capabilities
Preparing product reports by collecting, analyzing, and summarizing information and trends
Providing engineering information by answering questions and requests
Maintaining product and company reputation by complying with federal and state regulations
Maintaining product data base by writing computer programs and entering data

There are many sub-disciplines of electrical engineering. Some electrical engineers specialize exclusively in one sub-discipline, while others specialize in a combination of sub-disciplines. The most popular sub-disciplines are:

Electronic Engineer

Electronic engineers research, design, create, and test electronic systems and components to be used in areas such as telecommunications, acoustics, aerospace guidance, and propulsion control, or instruments and controls. This career is very similar to that of an electrical engineer - both careers are used interchangeably in the United States. The main difference is specialization. While electrical engineers take care of entire electrical systems, electronics engineers hone in on the smaller parts, such as individual computers, electronic circuits, resistors, capacitors, inductors, transistors and diodes and use their knowledge of electronic theory and materials properties.

Microelectronics Engineer

Microelectronics is a subfield of electronics and relates to the study and microfabrication of very small electronic designs and circuit components typically made from semiconductor materials. Many components of normal electronic design are also available in a microelectronic equivalent which can include transistors, capacitors, inductors, resistors, diodes, insulators and conductors. Microelectronics engineers use specialized equipment and unique wiring techniques such as wire bonding because of the unusually small size of the components, leads and pads. As techniques have improved, the scale of microelectronic components has continued to decrease, therefore, the impact of circuit properties such as interconnections may become of more interest. The goal of the microelectronics engineer is to find ways to minimize these 'parasitic' effects, while delivering smaller, faster, and cheaper devices.

Signal Processing Engineer

A signal processing engineer analyzes and alters digital signals to make them more accurate and reliable. Responsibilities include developing, managing and updating digital signals, and creating algorithms to process them more efficiently. A signal processing engineer can work in areas such as image processing, speech processing, pattern recognition, chip designing, radio frequency designs, biomedical signal processing, and space and military applications including satellite and mobile communications. Efficient use of signals arises from implementing precise algorithms coded in software packages with concise steps and real-time outputs. Engineers need to develop the steps needed, provide the specifications, design the processor which acts like the machine, and simulate the system pre-hand before the fabrication.

Power Engineer

A power engineer, also called a power systems engineer, deals with a subfield of electrical engineering that involves the generation, transmission, distribution and utilization of electric power, along with the electrical equipment associated with these systems (such as transformers, generators, motors and power electronics). Although much of a power engineer's focus is concerned with the issues faced with three-phase AC power, another area of focus is concerned with the conversion between AC and DC power and the evolution of specific power systems like those used in aircraft or for electric railway networks. Power engineers draw the majority of their theoretical base from electrical engineering.

Control Engineer

Control engineering, or control systems engineering, is typically taught along with electrical engineering at many universities, and specifically focuses on implementation of control systems obtained by mathematical modeling of a wide range of systems. This type of engineering discipline uses the automatic control theory to design controllers that cause systems to behave in a certain way, using micro-controllers, programmable logic controllers, digital signal processors and electrical circuits. By using detectors and sensors to measure the output performance of the controlled process and provide corrective feedback, desired performance can be achieved.

Telecommunications Engineer

Telecommunications engineering is a discipline centred on electrical and computer engineering which attempts to assist and improve telecommunication systems. A telecommunications engineer's work will range from doing basic circuit design, providing high-speed data transmission services, and overseeing the installation of telecommunications equipment (such as electronic switching systems, optical fibre cabling, IP networks, and microwave transmission systems). They use an assortment of equipment and transport media in order to design the network infrastructure (such as twisted pair, coaxial cables, and optical fibres) and provide solutions for wireless modes of communication and information transfer, such as wireless telephone services, radio and satellite communications, and internet and broadband technologies.

Instrumentation Engineer

Instrumentation engineering finds its origin in both electrical and electronics engineering and deals with the design of measuring devices for pressure, flow and temperature. In short, this field deals with measurement, automation and control processes which involves a deep understanding of physics. Instrumentation engineers develop new and intelligent sensors, smart transducers, MEMS Technology, and Blue tooth Technology. One can find instrumentation engineers working at almost all process and manufacturing industries involved with steel, oil, petrochemical, power and defense production.

Computer Engineer

Most universities offer computer engineering as either a degree, sub-discipline of electrical engineering, or offer a dual degree in both electrical and computer engineering. Computer engineers research, design, develop, and test computer systems and components such as processors, computer circuit boards, memory devices, networks, and routers, microchips, and other electronic components. They specialize in areas like digital systems, operating systems, computer networks, etc. Computer engineering attempts to match digital devices with software to meet the scientific, technological, and administrative needs of business and industry.

What is the workplace of an Electrical Engineer like?

Electrical engineers usually work in a lab, an office, a mine or in industrial plants. An electrical engineer usually can pursue a technical career in any industry. They usually supervise computer programmers, electricians, scientists and other engineers. A typical work week is composed of 40 hours although there might be some overtime to meet deadlines.

An electrical engineer also spends a lot of time doing project management, such as meeting with clients, determining budgets and preparing project schedules. Engineering projects usually require written documentation, so strong writing and communication skills are important.

Let’s read further what electrical and electronics engineering (EEE) is all about.

An Introduction to Electrical and Electronics Engineering

Before delving deeper into the scope of electrical and electronics engineering, it’s important to know about what electrical and electronics engineering is meant for.

What is Electrical Engineering (EE)?

Electrical engineering is the core study of the applications of electricity and electronics, which is one of the most chosen streams by engineering students. It was introduced dates back to the 19^th century. ‘Faraday’s Law of Induction’ brought revolution in Electrical Engineering by introducing new concepts of current flow. Mainly the electrical engineering study involves:

• Generation of electricity

• Transmission of electricity

• Distribution of electricity

The pioneer discoveries in electrical engineering are induction motors by Nicola Tesla, electric light bulb by Thomas Alva Edison, and radio by Guglielmo Marconi. These innovators transformed the scenario by implementing the concept of electrical engineering into practical devices. The specialized categories of EE encompass power generation and transmission systems, motors, batteries and control systems.

What is Electronics Engineering?

The electronics engineering revolves around the study of electronic devices, circuits, equipment, and systems.

The specific branches of electronic engineering mainly include:

• Analogue Electronics

• Digital Electronics

• Power Electronics

• Embedded Systems

• Communication Systems

In 1904, John Ambrose Fleming invented the thermionic diode vacuum tube and this invention is referred to as the ‘birth of electronics’. This vacuum tube worked as the foundation of all electronics of that time, including television, and radar. Later on, transistors replaced the vacuum tubes in 1947, which was the invention of William Shockley, John Bardeen and Walter Brattain at AT&T's Bell Laboratories.

Difference between Electrical Engineering and Electronics Engineering

Electrical and electronics are two related forms of engineering. However, most of the engineering UG and PG courses club these technologies together since both the technologies complement each other. B.Tech in Electrical and Electronics Engineering, B.E in Electrical and Electronics Engineering, and M.Tech in Electrical and Electronics Engineering are the major courses offered at engineering institutions. Electrical and electronics engineering can be distinguished by the functions performed in both the specializations. Below table might be a help:

Functions of Electrical Engineers	Functions of Electronics Engineers
Developing/ improving products by using electric power.	Building software, electronic components, and products for commercial, industrial and residential use.
Manufacturing and installation of electrical goods after performing detailed calculation.	Creating testing and maintenance environment for electronic components and equipment

Working Principle of Electric Generator

2018-06-30T04:16:00.000-07:00

When a conductor moves in a magnetic field, an emf is induced across the conductor. This is the only basis on which each and every rotating electric generator works. Let us discuss the matter in a little bit details so that we can easily understand how does an electrical generator actually work. According to Faraday's law of electromagnetic induction, when a conductor links with a changing flux, it will have an induced emf across it. The value of induced emf across the conductor depends on the rate of change of flux linkage with the conductor.

The direction of the induced emf in the conductor can be determined by Fleming's Right Hand Rule. This rule says that on your right hand if you stretch your thumb, first finger and second finger perpendicular to each other, and if you align your right hand thumb along the direction of motion of the conductor in the magnetic field, and first finger along the direction of magnetic field, then you second finger indicates the direction of emf in the conductor.

Now we will show you how does electricity get produced when we rotate single loop of a conductor in a magnetic field.

During rotation, when one side of the loop comes in front of the magnetic north pole, the instantaneous motion of the conductor will be upward hence according to Fleming's Right Hand Rule the induced emf will have inward direction.

At the same time, another side of the loop comes in front of the magnetic south pole, the instantaneous motion of the conductor will be downward hence according to Fleming's Right Hand Rule the induced emf will have outward direction.

During rotation, each side of the loop comes under magnetic north pole and south pole alternately. Again in the pictures, when any of the coil sides (conductors) comes under north pole the motion of the conductor would be upward and when it comes under south pole the motion of the conductor would be downward. Hence, the emf induced in the loop alters its direction continuously. This is the most basic conceptual model of an electric generator. We also call it as single loop electric generator. We can collect the induced emf in the loop in two different ways

Let us connect slip ring with both ends of the loop. We can connect a load with the loop through the brushes rest on the slip rings as shown. In this case, the alternating electricity produced in the loop comes the load. This is an AC electric generator.

We can also collect the electricity produced in the rotating loop through commutator and brush arrangement as shown in the animated picture below. In this case, the electricity produced in the loop (here the rotating loop of the single loop generator can also be referred as the armature) gets rectified through the commutator and the load gets a DC power. This is the most basic conceptual model of a DC generator.

Construction of Alternator

2018-06-30T04:00:00.000-07:00

Construction wise, an alternator consists of field poles placed on the rotating fixture of the machine i.e. rotor as shown in the figure above. The rotor rotates in the stator. The field poles get projected on the rotor body. The armature conductors are housed on the stator. An alternating three-phase voltage represented by aa’, bb’, cc’ is induced in the armature conductors thus resulting in the generation of three-phase electrical power. All modern electrical power generating stations use this technology for generation of three-phase power, and as a result, the alternator or synchronous generator has become a subject of great importance and interest for power engineers.

An alternator is basically a type of AC generator which also known as synchronous generator. The field poles are made to rotate at synchronous speed Ns = 120 f/P for effective power generation. Where, f signifies the alternating current frequency and the P represents the number of poles.alternator

In most practical construction of alternator, it is installed with a stationary armature winding and a rotating field unlike in the case of DC generator where the arrangement is exactly opposite. This modification is made to cope with the very high power of the order of few 100 Megawatts produced in an AC generator contrary to that of a DC generator. To accommodate such high power the conductor weighs and dimensions naturally have to be increased for optimum performance. For this reason is it beneficial to replace these high power armature windings by low power field windings, which is also consequently of much lighter weight, thus reducing the centrifugal force required to turn the rotor and permitting higher speed limits.

There are mainly two types of rotor used in construction of alternator,

Salient pole type.
Cylindrical rotor type.

Salient Pole Type

The term salient means protruding or projecting. The salient pole type of rotor is generally used for slow speed machines having large diameters and relatively small axial lengths. The poles, in this case, are made of thick laminated steel sections riveted together and attached to a rotor with the help of joint.

An alternator as mentioned earlier is mostly responsible for generation of very high electrical power. To enable that, the mechanical input given to the machine in terms of rotating torque must also be very high. This high torque value results in oscillation or hunting effect of the alternator or synchronous generator. To prevent these oscillations from going beyond bounds the damper winding is provided in the pole faces as shown in the figure. The damper windings are basically copper bars short-circuited at both ends are placed in the holes made in the pole axis. When the alternator is driven at a steady speed, the relative velocity of the damping winding with respect to the main field will be zero. But as soon as it departs from the synchronous speed there will be relative motion between the damper winding and the main field which is always rotating at synchronous speed. This relative difference will induce the current in them which will exert a torque on the field poles in such a way as to bring the alternator back to synchronous speed operation.

The salient feature of pole field structure has the following special feature-

They have a large horizontal diameter compared to a shorter axial length.
The pole shoes covers only about ²/₃rd of pole pitch.
Poles are laminated to reduce eddy current loss.
The salient pole type motor is generally used for low-speed operations of around 100 to 400 rpm, and they are used in power stations with hydraulic turbines or diesel engines.

Salient pole alternators driven by water turbines are called hydro-alternators or hydro generators.

Cylindrical Rotor Type

The cylindrical rotor is generally used for very high speed operation and employed in steam turbine driven alternators like turbogenerators. The machines are built in a number of ratings from 10 MVA to over 1500 MVA. The cylindrical rotor type machine has a uniform length in all directions, giving a cylindrical shape to the rotor thus providing uniform flux cutting in all directions. The rotor, in this case, consists of a smooth solid steel cylinder, having a number of slots along its outer periphery for hosting the field coils.

The cylindrical rotor alternators are generally designed for 2-pole type giving very high speed of

Or 4-pole type running at a speed of

Where, f is the frequency of 50 Hz. The cylindrical rotor synchronous generator does not have any projections coming out from the surface of the rotor, rather central polar area is provided with slots for housing the field windings as we can see from the diagram above. The field coils are so arranged around these poles that flux density is maximum on the polar central line and gradually falls away as we move out towards the periphery. The cylindrical rotor type machine gives better balance and quieter-operation along with lesser windage losses.

Principle of DC Generator

2018-06-30T03:33:00.000-07:00

There are two types of generators, one is ac generator and other is DC generator. Whatever may be the types of generators, it always converts mechanical power to electrical power. An AC generator produces alternating power. A DC generator produces direct power. Both of these generators produce electrical power, based on same fundamental principle of Faraday's law of electromagnetic induction. According to this law, when a conductor moves in a magnetic field it cuts magnetic lines of force, due to which an emf is induced in the conductor. The magnitude of this induced emf depends upon the rate of change of flux (magnetic line force) linkage with the conductor. This emf will cause a current to flow if the conductor circuit is closed.

Hence the most basic tow essential parts of a generator are

a magnetic field
conductors which move inside that magnetic field.

Now we will go through working principle of DC generator. As, the working principle of AC generator is not in scope of our discussion in this section.

Single Loop DC Generator

In the figure above, a single loop of conductor of rectangular shape is placed between two opposite poles of magnet.

Let's us consider, the rectangular loop of conductor is ABCD which rotates inside the magnetic field about its own axis ab. When the loop rotates from its vertical position to its horizontal position, it cuts the flux lines of the field. As during this movement two sides, i.e. AB and CD of the loop cut the flux lines there will be an emf induced in these both of the sides (AB and BC) of the loop.

As the loop is closed there will be a current circulating through the loop. The direction of the current can be determined by Flemming's right hand Rule. This rule says that if you stretch thumb, index finger and middle finger of your right hand perpendicular to each other, then thumbs indicates the direction of motion of the conductor, index finger indicates the direction of magnetic field i.e. N - pole to S - pole, and middle finger indicates the direction of flow of current through the conductor.

Now if we apply this right hand rule, we will see at this horizontal position of the loop, current will flow from point A to B and on the other side of the loop current will flow from point C to D.

Now if we allow the loop to move further, it will come again to its vertical position, but now upper side of the loop will be CD and lower side will be AB (just opposite of the previous vertical position). At this position the tangential motion of the sides of the loop is parallel to the flux lines of the field. Hence there will be no question of flux cutting and consequently there will be no current in the

loop. If the loop rotates further, it comes to again in horizontal position. But now, said AB side of the loop comes in front of N pole and CD comes in front of S pole, i.e. just opposite to the previous horizontal position as shown in the figure beside.

Here the tangential motion of the side of the loop is perpendicular to the flux lines, hence rate of flux cutting is maximum here and according to Flemming's right hand Rule, at this position current flows from B to A and on other side from D to C.

Now if the loop is continued to rotate about its axis, every time the side AB comes in front of S pole, the current flows from A to B and when it comes in front of N pole, the current flows from B to A. Similarly, every time the side CD comes in front of S pole the current flows from C to D and when it comes in front of N pole the current flows from D to C.

If we observe this phenomena in different way, it can be concluded, that each side of the loop comes in front of N pole, the current will flow through that side in same direction i.e. downward to the reference plane and similarly each side of the loop comes in front of S pole, current through it flows in same direction i.e. upwards from reference plane. From this, we will come to the topic of principle of DC generator.

Now the loop is opened and connected it with a split ring as shown in the figure below. Split ring are made out of a conducting cylinder which cuts into two halves or segments insulated from each other. The external load terminals are connected with two carbon brushes which are rest on these split slip ring segments.

Working Principle of DC Generator

It is seen that in the first half of the revolution current flows always along ABLMCD i.e. brush no 1 in contact with segment a. In the next half revolution, in the figure the direction of the induced current in the coil is reversed. But at the same time the position of the segments a and b are also reversed which results that brush no 1 comes in touch with the segment b. Hence, the current in the load resistance again flows from L to M. The wave from of the current through the load circuit is as shown in the figure. This current is unidirectional.

This is basic working principle of DC generator, explained by single loop generator model. The position of the brushes of DC generator is so arranged that the change over of the segments a and b from one brush to other takes place when the plane of rotating coil is at right angle to the plane of the lines of force. It is so become in that position, the induced emf in the coil is zero.

Electrical Engineer Needs to Know

2018-04-26T17:26:00.001-07:00

This article aims to help beginner engineers ensure that they have the skills most often looked for and tested during the hiring process but can also serve as a starting point for experienced engineers looking to shore up weakness in these areas.

Between the availability of almost turnkey design platforms and rising interest in the Internet of Things, opportunities for electronic product development have never been greater. To be a successful designer able to tackle a wide range of challenges, though, a developer should have a number of skills to draw upon. Here are ten of the most common and, in our opinion, valuable skills that electronic product designers will want to have:

1. Performing circuit analysis

From designing simple resistor circuits to analyzing the frequency response of complex networks, designers will need to know how to write and solve the equations of node and loop analysis to figure out how component clusters are operating. Simulation programs can help with the heavy math when needed, but knowing how to set up the analysis will still be necessary.

2. Working with op-amps

The workhorse in nearly every application that requires signals beyond ones and zeroes, the operational amplifier is a versatile device. Used properly, it is an amplifier, integrator, signal conditioner, level shifter, and many more useful analog elements. The trick is in understanding the characteristics and limits of real devices rather than the idealized behavior described in textbooks.

3. Understanding analog filters

While the design of active analog filters may not be needed in all product development, understanding the effect that components have on analog signals is still an important skill to have. The capacitance, inductance, and impedance of both components and circuit traces can alter even digital signals in ways that, if not understood and compensated for, may cause systems to fail.

4. Designing digital filters

These days, most audio, video, and wireless signaling go digital at some point in their travels, with many kinds of signal manipulation carried out in the digital domain. Knowing how digital filters work to manipulate the analog signal that underlies the data stream will prove essential to avoiding surprises, even if a developer only invokes canned functions instead of designing the filter.

5. Designing feedback control

Robots, air conditioning, autonomous vehicles, and many other systems depend on feedback control loops for their proper operation. (And such loops include filters, so see above.) Designers should know how control loops function, how to determine their effectiveness, and how to ensure that they are stable in their behavior. No one wants a system that goes “oops.”

6. Managing hot components

The power dissipation of processors is rising, as is the density of components in small spaces, so component overheating is a common concern. Designers will need to know their options for keeping things cool as well as how to analyze thermal transfer to make sure they have provided enough relief.

7. Working with RF

Not all that long ago, design in the radio frequency (RF) spectrum was a specialty discipline that most developers never had to be concerned about. But with the IoT demanding wireless connectivity and rising clock speeds turning PCB circuit traces into RF waveguides, a basic understanding of how RF signals propagate and transfer energy is proving essential.

8. Appreciating firmware

Like it or not, more than half of the design effort in the electronics industry today involves software, and most electronic systems utilize a microprocessor or microcontroller to provide some or all of their functionality. However, hardware design decisions can have a substantial impact on the ease and effectiveness of code development. So even if not directly involved in the programming effort, a developer should have some understanding of what firmware is, how it’s created, and its role in making things work.

9. Using statistics for manufacturability

Getting a prototype to work in the lab is only the first step in creating a product for market. The design must be robust enough to accommodate all of the variations in component value that will occur during mass production and the wide range of operating environments that the product will face. Statistical analysis is the tool that developers will need to ensure that their design will work in the face of this uncertainty.

10. Managing the career

Along with all their technical knowledge, developers should have some basic business and career management skills. Landing and keeping a job, growing their access to opportunities and compensation, rising in the hierarchy or launching an entrepreneurial endeavor, and maintaining long-term satisfaction in the work effort all require conscious effort as well as interpersonal and team interactions. Working toward a destination, even one that changes from time to time, provides far more reward than simply reacting to whatever comes up.
