Variable speed drives generate high voltage spikes in all electric motors. Variable speed drive motors withstand the high voltage
 spikes that are generated by variable speed drives, whereas general purpose motors do not. General purpose motors do not have the insulation required to withstand high voltage spikes, so the motor winding on a general purpose motor used with a variable speed drive begins to breakdown, and ultimately, the winding will burn up.

Variable speed drives used on electric motors that are 100hp (or greater) induce harmful voltage levels on the electric motor shaft. When harmful voltage levels exceed the resistance of the motor bearing lubricant, those voltage levels dissipate to the electric motor’s bearing housings. Harmful voltage levels sent to a motor’s bearing housings eventually leads to bearing failure in the electric motor. Variable speed drive motors use special bearings that are designed to withstand the harmful voltage levels that are induced by variable speed drives.   

 General purpose electric motors can be driven by variable speed drives, but once the general purpose motor fails, an inverter duty motor should replace the general purpose motor. Precision Electric recommends maintenance technicians who use general purpose motors on variable speed drive applications to keep a spare inverter-duty motor to minimize downtime. 

Variable speed drive motors are more expensive than general purpose motors, but the increase in cost is worth preventing
downtime in variable speed drive applications when low speed is present. Many variable speed drive applications do not need to operate at low speeds, so variable speed drive motors are cost-prohibited in applications where low speed is not required.

Equipment failure is the number one factor in production loss for manufacturing facilities across the globe. It’s important that manufacturing facilities keep spare servo motors on the shelf, to maximize overall production. Most of Precision Electric’s customers keep rebuilt spare Mitsubishi servo motors on their shelf. Once their primary Mitsubishi servo motor fails, the spare is swapped out with the failed unit. The failed Mitsubishi servo motor is then sent to Precision Electric for routine maintenance repair.

Precision Electric routine maintenance of Mitsubishi servo motor repair can save manufacturers hundreds of thousands of dollars in production loss, as well as repair costs. Precision Electric routine maintenance consists of removing all parts of a Mitsubishi servo motor, cleaning parts and motor winding, replacement of bearings, repair bearing housings if needed, dynamic balance, testing of all electrical components, assembly of servo motor, and final test with motor.

The intent of routine maintenance is to provide manufacturing facilities with optimal production, and also to prevent Emergency or Rush repair services on Mitsubishi servo motors.

Keeping a spare Mitsubishi servo motor is the best method for manufacturing facilities to save on repair costs. If a manufacturer has a spare Mitsubishi servo motor, the failed Mitsubishi servo motor doesn’t need to be worked on around the clock until it has been completely rebuilt.

Precision Electric consistently expands it’s industrial electronics repair services because customers demand it. With the wide array of servo motors and drives in the market, a substantial need for ever-changing servo motor and drive repair services are needed.

There has always been three primary issues with servo motor and drive replacement- Servo motors and drive combinations are frequently proprietary and difficult to replace. Original Equipment Manufacturers (OEMs) retire older models of servo motor and drive equipment. The cost of replacement servo motor and drive combinations are often extremely high.

The demand of servo motor and drive repair is created by the Original Equipment Manufacturers’ ever-changing technological advancements. Most manufacturing facilities, however, often seek out servo motor and drive repair to cut down the cost associated with replacing obsolete equipment with new equipment.

The components Original Equipment Manufacturers use to build servo motor and drive combinations are often cheaply made. During a servo motor and drive repair, Precision Electric replaces these parts with quality parts that exceed the quality control of the Original Equipment Manufacturer.

What does this mean? It means that the servo motor and drive repair you receive back from Precision Electric is likely in better quality than the original equipment itself. 

Using proprietary software, Precision Electric can re-align the servo motor as necessary to ensure the rewinding of the motor retains full accuracy. Precision Electric has nearly 20 years experience with servo motor and drive repair, and can also find obsolete components and parts for the toughest servo motor and drive repairs.

Precision Electric designates each DC electric motor repair to a specific mechanic, so the mechanic who disassembles the DC electric motor is the same mechanic who assembles and final tests the DC electric motor.

When Precision Electric facilitates a DC electric motor repair, an initial test procedure is performed to determine cause of failure and other problems which may exist, including armature and field frame rewinds.

Precision Electric performs rewinds on-site and is known to work around the clock on emergency jobs until DC electric motors are repaired and ready to be installed back into production.

DC electric motor repair introduces additional complexities into the repair process. The addition of a commutator with brushes, and rotating armature coils subjected to centrifugal force, which aren’t factors involved in typical AC electric motor repair. 

The following procedures and tests are performed at Precision Electric to guarantee a quality DC electric motor repair.

Conductive carbon dust left by worn brushes is cleaned from the armature; then each commutator is checked for grounds and bar-to-bar shorts with detailed electrical testing.

Coils are manufactured in-house to assure proper fit. This eliminates constant bending and shaping during installation which can damage coil insulation. Proper banding is critical in DC repair. This ensures that the winding is held in position during high-speed operation. 

Field coils are checked using voltage drop testing. Bad fields and inter-poles are rewound in our shop on custom forms. TIG welding is available to eliminate soldered joints where design dictates. 

All commutators are turned, undercut, and chamfered to provide the best possible surface for brush contact. For corrosive or other severe duty environments, commutator platinum plating is available to extend wear life (pickle-duty). Neutral setting adjustments are made during final machine testing to ensure proper operation.

All DC electric motor repair performed by Precision Electric is backed by a 12-month in service warranty. The Precision Electric in service warranty provides customers with a peace of mind knowing that their spare DC motors will be warrantied regardless of how long their spare equipment is on standby.

Variable frequency drives (VFD) are also known as variable speed drives (VSD),  and inverters. Variable frequency drives are designed to control the speed of an alternating current (AC) electric motor. Variable frequency drives can reduce energy costs up to 50% by speed reduction on applications where the full speed (RPM) of the electric motor is not required.

This energy savings is often significant enough to pay for the variable frequency drive within a couple of months. Variable frequency drives are commonly used on pump, fan, and air compressor applications, and are often used in manufacturing facilities to increase or decrease the start up time on alternating current (AC) motors.

Increasing and/or decreasing the start up time on an AC motor can add years to the overall lifespan of an AC motor, and can also improve efficiency on production demands. Variable frequency drives provide the ability to control the frequency of starting and stopping an AC motor. This ability provides a means by which an AC electric motor is only operating when needed. AC electric motors have a longer lifespan if they are not continuously operating when they do not need to be.

There are a few different types of variable frequency drives. The most common type of variable frequency drive is known as a V/Hz (volts per  hertz), and are applied to applications such as fans, pumps, air compressors, and other related applications where high starting torque is not required. V/Hz variable frequency drive applications typically do not require full torque when the AC motor is operating at less than the base speed (RPM) of the electric motor.

Another type of variable frequency drive is known as a vector control. Vector control is used on variable frequency drives where high starting torque and full torque at low speed (RPM) is present. Vector control variable frequency drives are usually more expensive than a V/Hz drives.

There are other types of variable frequency drives that are more complex than V/Hz and vector control. These more complex variable frequency drives are typically used for precise speed regulation of an AC motor as well as complex programming to regulate starting and stopping of an AC motor.
