Viper returning to LeMans

http://feeds.feedburner.com/denbaguztadvanced (den baguzt group) — Tue, 25 Dec 2012 05:30:00 +0000

Following the launch of a new Viper and four races this past summer, the SRT Motorsports team is planning a full-time return to the American Le Mans Series (ALMS) in 2013.
The Viper had three top-10 finishes in the four ALMS events it entered; the team is planning to have two Viper GTS-R cars to work with in 2013, as it did in its late summer campaign.
SRT Motorsports partnered with Riley Technologies to design and build the competition-ready, non-street-legal SRT Viper GTS-R.
The Viper’s racing heritage began in 1996 with the first Dodge Viper racing entry, the original GTS-R, which earned five international GT championships and the 1997-1999 FIA GT championships. It also posted an overall win at the Rolex 24 Hours of Daytona in 2000 – the first for a production-based American car.
Viper finished one-two at the 24 Hours of Le Mans in GTS class in three consecutive years, 1998-2000, and also captured GTS Class and driver’s championships in the American Le Mans Series in 1999 along with the Series Class, manufacturer’s and driver’s championships in 2000.
The Dodge Viper Competition Coupe, launched in 2003, continued the on-track prowess by capturing the 2004 SCCA Speed World Challenge GT title, championships in Formula D Drifting series in 2004 and 2006 and the British GT Championship in 2007 and 2008.

Viper: just under $100,000

http://feeds.feedburner.com/denbaguztadvanced (den baguzt group) — Tue, 25 Dec 2012 05:29:00 +0000

SRT has released the retail prices for both Vipers. The 2013 SRT Viper model will be $97,395 ($99,390 with destination), while the 2013 SRT Viper GTS model will be $120,395 ($122,390 with destination). A gas guzzler tax is likely to bring the price over $100,000, but the amount of the tax is unknown pending official gas mileage figures.
The SRT Viper GTS adds more technologically advanced solutions, including two-mode active suspension, and other performance features. Under the hood of both models is the all-aluminum, mid-front 8.4-liter V-10 engine that delivers 640 horsepower and 600 lb.-ft. of torque – the most torque of any naturally aspirated sports car engine, according to the company.
Both SRT Viper and SRT Viper GTS have new interior and exterior designs with premium materials and a triple-digit weight reduction which brings a Viper-best power-to-weight ratio. The 2010 Dodge Viper cost $90,255 before destination and gas-guzzler tax.
Larry Vellequette of Automotive News pointed out that the Viper’s list price is lower than that of the Chevrolet Corvette ZR1, whose horsepower and torque is nearly as high; the ZR1 costs $113,575, including delivery and $1,000 gas-guzzler tax. The high Viper destination charge is likely lower than the company’s actual costs, since all Vipers will be sent to the dealer via covered truck rather than rail.
Production begins at the Conner Avenue Assembly Plant in Detroit, the home for Viper since 1995, in November 2012. Dealer orders are expected to begin in mid-November 2012. Only 2,000 Vipers are to be built each year; this time, dealers will need to pay a $25,000 fee and send associates for training to sell the cars. According to Automotive News, Ralph Gilles said that only 15%-20% of Chrysler’s dealers will be able to sell them nationwide.

Vipers are shipping

http://feeds.feedburner.com/denbaguztadvanced (den baguzt group) — Tue, 25 Dec 2012 05:28:00 +0000

SRT Vipers are being built at the Conner Avenue plant, according to Allpar sources, but strict quality control is restricting production somewhat.
Since Fiat took control, Chrysler’s quality standards have risen sharply, and dimensional control has become more demanding. There have been numerous cases of “quality over production” already established, as Chrysler struggles to establish a reputation for reliability and overcome public perceptions.
Vipers are reportedly shipping out to their new owners, though the pace is slow, and triple digits haven’t been reached yet.

A deeper look at the Dart DDCT fix

http://feeds.feedburner.com/denbaguztadvanced (den baguzt group) — Tue, 25 Dec 2012 05:26:00 +0000

Michael Volkmann provided photos of a Fiat dual-dry-clutch transmission being repaired under the Dodge Dart DDCT recall. The transmission provides the direct-contact efficiency of a manual, but automatically shifts itself; this particular design was tuned carefully to feel more like a traditional hydraulic-activation automatic than most dual-clutch units.
According to Chrysler, the clutch slave cylinder may have been made incorrectly, causing a fluid leak. The issue only affects transmissions made in a certain date range, and customers are being notified. Dealerships have reportedly been told to fix all cars they have on the lot before selling them; if they sell the car before fixing it, the dealer will reportedly have to cover the labor costs.
The instructions are highly detailed, with over 100 steps, and while the transmission has to be completely removed before servicing, the case does not have to be opened. The slave cylinder is on top of the transmission. Technicians must measure how far the threaded end of the input shaft is sticking out; this measurement is critical. (For more information and other new photos, see our Fiat dual-dry-clutch transmission page.)

Fiat will produce new Jeep, Fiat at Melfi plant

http://feeds.feedburner.com/denbaguztadvanced (den baguzt group) — Tue, 25 Dec 2012 05:25:00 +0000

With Italian Prime Minister Mario Monte watching, Fiat Group Chairman John Elkann and Fiat/Chrysler CEO Sergio Marchionne announced plans to build a new Jeep and a new Fiat at the plant in Melfi, Italy. Production will begin in 2014.
Following an investment of more than $1.3 billion, Melfi will be one of the most advanced assembly plants in the world. The changes and improvements have already begun.
Those upgrades include modifications to accommodate the new modular Small Wide platform that easily be adapted to produce larger vehicles. The platform is already compliant with U.S. standards meaning that vehicles produced at the Melfi plant will be export ready without for further modifications.
The first of the two new models will be a Jeep that marks the brand’s entrance into a new market segment. Melfi will be the only plant in the world to produce this model, which will be sold worldwide. Melfi will also build the 500X, which is larger, more spacious and more capable than the 500L launched three months ago.
Once the plant upgrades are complete, Melfi will have increased flexibility with the ability to produce up to four different models on the same assembly line.
Total production capacity based on three shifts will be 1,600 vehicles per day

Toyota to borrow Fury, uh…

http://feeds.feedburner.com/denbaguztadvanced (den baguzt group) — Tue, 25 Dec 2012 05:24:00 +0000

Toyota has announced that it will show a concept car code-named Furia at the Detroit Auto Show next month. The sedan is likely to experiment with ideas for the Toyota Corolla, which is being updated next year. Furia appears to continue trends from the Scion FR-S.
The name is very close to Plymouth’s long-standing Fury, which debuted in 1956 as a high-performance muscle car, capable of over 140 mph. The Plymouth Fury continued as a performance car into 1957 and 1958, when Motor Trend timed it doing 0-60 in 7.7 seconds (Impala ran 9.1 and Fairlane 500, 10.2). In 1960, the name was devoted to all top-of-the-line Plymouths, and performance was relegated to the Sport Fury.
Many Americans recall the final Fury lines of the 1970s, when the name was put onto what had been the mid-sized Plymouth Belvedere; it gained tremendous popularity as a police car, and can still be seen on numerous TV programs in reruns, including Hill Street Blues and T.J. Hooker. The large Fury continued under the name Gran Fury; that name was later attached to Plymouth’s version of the Dodge Diplomat/Chrysler New Yorker in the 1980s.
The Fury name was dropped in the United States after the 1989 model year, along with the final rear-wheel-drive sedans of the old Chrysler Corporation. [See: the Plymouth Fury]

Baby-Viper: Gilles off the cuff

http://feeds.feedburner.com/denbaguztadvanced (den baguzt group) — Tue, 25 Dec 2012 05:23:00 +0000

According to Drive.com.au’s Toby Hagon, SRT chief Ralph Gilles hinted about creating a ”baby Viper.” He quoted Gilles as saying:

“Going forward, of course, my dream is to continue making unique SRT products, something like a baby Viper or something like that.”

From there to actually believing that a baby Viper is being considered is a long leap, but one that Hagon was willing to make. While he admitted that “Gilles wouldn’t be drawn on the chances of a baby Viper or how it would come to life,” Hagon speculated on how a smaller, more efficient Viper could help with fuel economy targets (though Viper’s small production numbers are unlikely to harm Chrysler much), and tossed out the Alfa Romeo 4C and next-generation Mazda MX-5 roadster (which Alfa is working on) as possible platforms.

One could also speculate that the upcoming rear-wheel-drive mid-sized platform to be shared by Alfa Romeo and Dodge would be a good potential chassis, but in all likelihood a true “baby Viper” would require either its own custom designed chassis, or one borrowed from Ferrari.

It is also quite possible that Gilles was making a throwaway remark which has been thoroughly blown out of proportion. In past examples of the “echo chamber” nature of some reporting communities, remarks or speculation are picked up by other sources, and each time one or more provisio is dropped, until it reaches the eyes of a high-circulation print publication. Appearing in print — or on the web site of a print publication — often gives the rumor a level of authenticity it does not deserve, and since these publications usually do not credit “lesser” sources, or condescendingly refer to “blogs,” the writers who originated the story then gain confirmation. In the best case, the attention convinces the manufacturer to actually create the rumored object.

NRA: Ram is vehicle of the year

http://feeds.feedburner.com/denbaguztadvanced (den baguzt group) — Tue, 25 Dec 2012 05:22:00 +0000

The National Rifle Association (NRA)’s American Hunter magazine has declared Ram Outdoorsman its vehicle of the year (thanks, Jeff Crane). The magazine reported:

Take a tough-running, off-road go-getter and add unique bins for transporting firearms and other shooting gear, and you’ve got the Outdoorsman, Ram’s blockbuster hit in the pickup market. … The revamped 1500 Outdoorsman retains everything that made it the premier huntin’/work/do-everything pickup, but will roll into market (October) with almost-starship-worthy technology that ensures this RAM [sic] is just as perfect for highway cruising as it is for beating a trail into the backcountry. And not just that: It can do so even while delivering way more horsepower and torque despite slashing fuel use by 20 percent.

Aside from mixing up a brand named after a hood ornament with random-access memory, it is a ringing endorsement of the new Ram pickups.

Chrysler launches 300 Motown

http://feeds.feedburner.com/denbaguztadvanced (den baguzt group) — Tue, 25 Dec 2012 05:19:00 +0000

The new 2013 Chrysler 300 Motown, according to Chrysler, “pays tribute to the Motor City’s resurgence and determination through Detroit-born style and world-class ingenuity. Harking back to the days when bright work ruled Woodward and Jefferson Avenues, this limited-edition Chrysler flagship sedan includes bright chrome front and rear fascia accents, mirror caps, door handles and daylight-opening surround, and a unique Mopar bright chrome grille with seven sculpted horizontal blades. Large 20-inch polished ’heritage’ design aluminum wheels provide an elegant look, while its touring-tuned suspension delivers world-class levels of ride, handling and comfort. Completing this Chrysler flagship sedan’s curb appeal are black accented Chrysler wing badges and ‘Motown’ fender badges that transcend the city’s rhythm and spirit. Available exterior colors include Bright White, Gloss Black, Deep Cherry Red and new Jazz Blue.”
The interior uses pearl white Nappa leather seats with perforated inserts, placed in an otherwise black interior, with debossed logos on the front seatbacks; the car uses satin silver finished accents and real black olive ash wood trim. The stereo will include 100 tracks from original Motown recording artists (it appears they will be pre-loaded onto an SD card). The car includes ten-speaker Beats audio with a 12-channel amp and a standard 292 horsepower V6 engine rated at 31 mpg highway. The retail price of the car will be $33,990 including destination.

Jeep, Fiat returning to India

http://feeds.feedburner.com/denbaguztadvanced (den baguzt group) — Tue, 25 Dec 2012 05:08:00 +0000

Posted on December 23rd, 2012 • by David Zatz

Jeep and Fiat are planning to return to India in force, according to IndianAutosBlog. Jeep, which sells in 120 countries and was acquired by Kaiser precisely because of its worldwide presence, will be bringing out the Wrangler and Grand Cherokee in the third quarter of 2013. These will be followed by the much-discussed small SUV built in Italy, in 2015, and by the Patriot/Compass replacement in 2016.
The plan is for Fiat to have 112 dealers and for Jeep to have 82 dealers across India by 2016. Fiat will launch four new products in the next two years, including an Abarth; the new Punto will be launched in 2014 and refreshed in 2015 and 2016. A B-segment Fiat SUV and new Linea will appear in 2014, while the current Fiat Linea will be rebadged to “Linea Classic” in 2013. Fiat currently has less than a 1% market share.
Starting in 1949, Willys Jeeps were made locally by Mahindra & Mahindra, as part of a collaboration with Willys Overland. In 1974, a new collaboration agreement was signed with Jeep, then part of AMC. Mahindra switched to Peugeot in 1979. Mahindra & Mahindra created a new automotive division in 1994 and still sells local Jeeps through 275 dealers. The product line includes the Liberty-lookalike Scorpio, which M&M claims is entirely locally designed; what appears to be a Wrangler-based pickup, the Mahindra; and a number of other vehicles with more or less resemblance to the current Wrangler and past Jeeps. This resemblance is likely a carryover of the early Willys designs and looks. Engines appear to be from Peugeot.
Ironically, Premier, which had started by selling Plymouth and Dodge cars and trucks, switched to Fiat in the mid-1950s. [See the full story of Chrysler and Jeep in India]

SRT8 Core coming to US, Australia

http://feeds.feedburner.com/denbaguztadvanced (den baguzt group) — Tue, 25 Dec 2012 05:05:00 +0000

Following the apparent success of the Dodge Charger Super Bee, an SRT8 which a small number of options removed and a roughly-$3,000 price cut, Chrysler has not only brought back the Super Bee for 2013, but is planning a Chrysler 300C SRT8 Core model, according to reliable source oh20. .

While the SRT8 Core has already been announced for Australia, the new model — in the works for some time now — has not yet been officially unveiled for sale in North America. The Australian version of the Chrysler 300C SRT8 Core, which is likely to be similar or identical to the North American version aside from being right-hand drive, will forgo the adaptive cruise control, front parking sensor, adjustable suspension, and special wheels; it will retain the specially tuned suspension, big brakes, and 6.4 liter Hemi V8. It might be slightly lighter than the standard SRT8 due to the lower amount of equipment, though any weight change is likely to be marginal. The savings in Australia is around AU$6,000; in the US, it would likely come to between $5,000 and $6,000.

The Charger SRT8 Super Bee, which drops some equipment and adds Super Bee graphics, was, according to oh2o, responsible for nearly a third of domestic Charger SRT8 sales, appealing to those who want the performance but don’t care as much about the frills. The SRT8 will still be very well equipped.

8 ways to get your car ready for winter weather

http://feeds.feedburner.com/denbaguztadvanced (den baguzt group) — Sun, 02 Dec 2012 17:19:00 +0000

As another year winds down, for many people, annual and season-ending chores are in full swing. Rake the leaves. Clean the gutters. Get the furnace prepared for winter. But seasonal chores aren’t limited to homeowners – car owners should also include these winterizing essentials to their end-of-the-year to-do list:

1. Check the tire pressure

As temperatures fall in colder weather, the air pressure in your tires will naturally drop, too. In fact, your tire’s car lose as much as 1 pound per square inch of pressure for every 10 degrees Fahrenheit the temperature drops.

That loss can be significant when temperatures in colder climes plummet to 30 degrees or below. Take five minutes to make sure your tires don’t need a quick recharge. And don’t forget to check all four tires and the spare.

2. Check your tires

While you’re at checking the tire pressure, you should also give your tire treads a thorough inspection, too. Traction is important year-round, but it’s especially crucial during the winter when roads get slick with snow and ice.

If you don’t have a tire tread depth gauge handy, you can rely on the age-old trick of using a penny to determine tread depth. Insert the penny with the top of Lincoln’s head facing the tire tread into the groove. If Lincoln’s head is covered, you probably have adequate tread depth. But if you can see all of Lincoln’s head, it’s time to get new tires.

Uneven wear, bulging sidewalls, abnormal nicks or holes are all additional signs it may be a good time to purchase new tires.

3. Replace wiper blades

The driver’s ability to see clearly through the windshield is paramount in winter. Quick response time is vital and in colder climates, salt deposits, frost and blowing now can all easily obstruct vision. If your car’s wiper blades aren’t doing a good job of clearing the windshield now, how will they perform against frost, snow and sleet?

Check your blades ahead of time and replace blades that are cracked or don’t cleanly sweep across the windshield.

4. Check the windshield defroster

"Winter usually means that your your vehicle's windshield defrosters will be used on a regular basis," says Ron Montoya, consumer advice editor for automotive tips and advice site Edmunds.com. "It's a good idea to check that they are in working order." He adds it's also a good idea to make sure your heating system is in working order before it gets too cold.

5. Inspect the coolant system

Yes, even though it’s cold out, your car’s coolant system is an important feature during cold-weather driving. If you have had a recent radiator flush, you should be more than prepared for winter. Otherwise, check to make sure that your radiator fluid levels are adequate, that you’re using the proper coolant and that all hoses are in good condition without wear indicators like cracks, bulges or stiffness.

6. Check the battery

Your car’s battery will be one system that will have to work harder during the colder months of the year. Cold-weather starts can quickly deplete an older battery, so check your battery’s condition before temperatures become low.

Check the installation date that may be marked on top of the battery. If your car’s battery is older than two to three years, consider buying a new one. Clean battery terminal connections are important, too, so look for any signs of whitish powder that signals corrosion at the battery posts. You can remove buildup with a solution of baking soda and warm water. After cleaning, make sure all the connections are tight.

7. Get a tune-up

Your car’s engine works harder in the cold, so it’s important to make sure it’s working at an optimum level. An engine that sputters or struggles to start in warm weather will only have more trouble when cold weather arrives. A tune-up by a qualified mechanic or auto service center manes you'll be proactively diagnosing and fixing small problems, as well as adjusting the vehicle's performance to manufacturer’s recommendations, which can help make sure your car has no problem running smoothly throughout the winter.

8. Put an emergency kit in the trunk

Even the best-maintained vehicles can break down or get involved in a slide-off, stranding or accident. A driver left stranded on the side of the road during warm months may be inconvenienced and frustrated, but safety is a serious concern in cold weather.

Be prepared for those circumstances by equipping your vehicle with the supplies and tools you may need to stay safe when stranded with your vehicle in cold weather. Recommended kit supplies include fire extinguisher, a hazard triangle or warning flares, blankets, a tire gauge, a spare tire jack and lug wrench, tire repair kits, jumper cables, a shovel, jumper cables, a flashlight, and gloves.

Rise of the PM machines

http://feeds.feedburner.com/denbaguztadvanced (den baguzt group) — Sun, 02 Dec 2012 17:14:00 +0000

Permanent magnet brushless synchronous motors have moved beyond traditional applications with higher efficiency than induction machines.

No relation to the Terminator 3 saga, this “rise” refers to the expanding applications and growing physical sizes for today’s permanent magnet (PM) machines—motors, generators, and other devices. Times have changed the notion that PM machines comprise mainly small ac (and dc) motors.

PM brushless synchronous motors have moved well beyond machine tool, CNC, and related traditional applications. Even here sizes have grown, for example, up to 220 kW rated power from Fanuc Ltd. Newer PM machine applications include general-purpose industrial processes, electric hybrid vehicles, magnetic (variable-speed) drives, and generators for giant wind turbines. The objective is high efficiency by cutting rotor losses compared to induction machines.

One notable general-purpose product development is Baldor Electric’s RPM AC line of PM synchronous motors. The design combines a laminated steel frame stator and a salient-pole, interior PM (IPM) rotor for power density and efficiency (see Online Ref. 1). Rich Schaefer, marketing manager for variable speed and specialty motors, explains that RPM AC series ratings are now available up to 700 hp (522 kW) in standard air-cooled version. Still higher ratings apply to water-cooled units, such as a gearmotor developed for the drilling industry, rated at 1,020 hp and able to produce 35,000 lb-ft (47,460 N-m) torque in a very compact space, Schaefer notes.

Indicative of further power growth ahead is a development for electrically driven gas compressors from GE Global Research. GEGR described a 6 MW, high-speed drive motor prototype at a March 2009 workshop staged by the U.S. Dept. of Energy and others (see Online Ref. 2). Efficiency and other benefits make PM machine topology the preferred choice above 15,000 rpm speeds, says GEGR.
Material issues

PM machines rely on so-called rare-earth magnet materials—typically neodymium-iron-boron (Nd-Fe-B)—for high torque production. Wider applications mean more demand for magnets whether used in small amounts for high volume products or in large quantities for fewer big machines. The latter translates to hundreds of pounds of magnets per unit, even with IPM rotor design that reduces magnet weight needed for a given torque output. IPM design generates an added reluctance torque component.

Synchronous PM generators for multi-megawatt wind turbines also pose large magnet demands. “In a high-speed generator, magnet weight is in the 150-200 kg (330-440 lb) range,” says Anders Troedson, vice president of The Switch Controls & Converters Inc., a manufacturer of large generators. However, magnet weight skyrockets for slow-speed, direct-drive generators due to the large diameter machine and number of poles needed for torque production (see Online Ref. 3). “The lower the shaft speed the higher the torque required for the same output power,” states Troedson. “Mass of magnets in a large direct-drive generator exceeds two metric tons.” That’s more than 4,400 lb!

Growth of PM machine applications has prompted initial concern that a supply-demand crisis may be coming for rare-earth magnets. Experts see a less critical scenario. “We are not running out of raw materials or production capacity,” notes Troedson. He thinks increased demand will spur manufacturing competition so that magnet prices are not likely to accelerate.

“There is an abundance of rare-earth magnet raw material. The need is to ensure consistent production quality and careful supplier selection,” adds Baldor’s Schaefer.

Energy-Efficient Electric Motors

http://feeds.feedburner.com/denbaguztadvanced (den baguzt group) — Sun, 02 Dec 2012 17:07:00 +0000

Concern for the environment may motivate private individuals and the general public, but it’s a poor reason for making business decisions. Companies buying and installing electric motors have a far better business reason for trying to save electricity— making their operations more cost-efficient. In a rare confluence of factors, reducing electricity usage by installing more energy-efficient electric motors promotes both of these goals. And, it might be a requirement as of Dec. 19, 2010, the next major U.S. motor efficiency compliance deadline.

When one talks about high-efficiency motors, it is important to note that this term really refers to traditionally architected electric motors consisting of armature and field windings. “Induction motors are available in standard-, high- and premium-efficiency models,” said David Hansen, global product manager, Kinetix Motion Control, Rockwell Automation, “whereas permanent magnet motors are not.”

Source: Baldor and Control EngineeringThe reason is that the permanent-magnet electric motor architecture is inherently more efficient, since no power is used to establish the stator magnetic field. John Malinowski, senior product manager - ac motors, Baldor Electric Company, pointed out: “ac induction motors have a family of motors that comply with NEMA Premium Efficiency per NEMA MG 1, tables 12-12 and 12-13, and IEC 60034- 30 [standards] for IE3 efficiency.”

For that reason, we limited this discussion to induction motors having stator coils wound on ferromagnetic cores, and save looking at the energy-efficiency characteristics of permanent magnet motors for a later discussion.

“Premium motors,” Malinowski continued, “are built to closer tolerances than older motors, run cooler, have less vibration, are quieter, and last longer.”

What makes a motor efficient?

“The key to higher efficiency is reducing losses,” Malinowski said. “More copper in the winding to reduce stator losses, and higher-grade electrical steel reduces iron-core losses. Lower losses mean fewer watts to cool so smaller fans can be used, [further] reducing losses.”

Fischbach added: “The majority of the losses are caused by conductive losses in the stator and rotor and core losses, also called iron or hysteric losses.”

Hansen listed a number of design features that give these motors their high efficien

    Winding Resistance—As winding resistance increases, efficiency decreases. To maximize motor efficiency, motor designers minimize resistance by maximizing slot fill (amount of copper windings in the stator slots) and minimizing end-turn radius (amount of copper windings outside the stator slots).
    Lamination Material—Core losses are directly influenced by the material properties and quality of the steel used in the stator laminations. In addition, thinner laminations will lead to lower core losses in the stator than thicker laminations.
    Lamination Tooth Geometry—Lamination tooth geometry impacts concentration of the magnetic flux inside the motor. Geometries that provide higher magnetic flux concentration will have lower stray losses and therefore higher efficiency.

It’s the system that counts

“The goal in most factory automation and industrial applications,” Fischbach suggesteded, “is efficient use of energy with the highest productivity. Therefore it is essential to analyze, model, and optimize the complete system before investing in individual components, like new motors.”

Table shows details of European motor efficiency deadlines. Source Lenze and Control EngineeringMalinowski agreed: “Better motors are easy to do as drop-in replacements [for less efficient units] but efficiency gains are limited. Using a 95% efficient motor is good but not when connected to a double-reduction [geartrain] that is 50% to 60% efficient, when a helical or bevel speed reducer may be 90% to 95% efficient.”

Fischbach also concurred: “Higher efficiency is a relative term there since we also have to consider other factors [that] affect the overall system efficiency, like cycle time or product output. For example, a direct drive torque motor with 80% efficiency could save more energy than a 95% efficient servo motor by eliminating inefficient drive train elements like gear boxes—and significantly increase production, too.”

What not to do

“The biggest mistakes,” Fischbach warned, “are made by engineers just focusing on the name plate efficiency of the motor, and expecting similar percentage energy savings in their specific application.

Different motors have different characteristics, which have to be matched to the application to benefit from the investment in a higher efficiency motor. For example, a more expensive premium efficiency ac induction motor will not save much energy if it’s run at partial load or idling for long periods of time.”

Malinowski provided the example of replacing a much older motor with a new premium motor on a centrifugal pump. The impeller would have been sized for the old motor’s speed. However, the new, more efficient, motor likely will run faster under the same load, leading to more overall power use. The system might be more energy-efficient, but the additional work it does may not provide any benefit.

“Designers who are truly interested in increasing efficiency,” advised Hansen, “will not simply look to replace a motor, but will take a holistic view of the overall machine design. Even a perfectly efficient motor, if connected to a poorly designed mechanical system, will not produce significant benefits with respect to energy savings. Any mechanical power transmission device between the motor and the load will have inherent inefficiency. The highest precision helical planetary gear heads, brand new out of the box, are at best 90% to 95% efficient. Worm gear boxes can be as little as 50% to 60% efficient.”

“The ultimate solution in terms of machine efficiency,” he concluded, “would be to eliminate the mechanical power transmission devices altogether through the use of direct drive permanent magnet servo motors.”

New Motors Reach New Applications

http://feeds.feedburner.com/denbaguztadvanced (den baguzt group) — Sun, 02 Dec 2012 16:31:00 +0000

Electric motors are the mechanical muscle power that drives fans, blowers, pumps, printers, disk drives, ATMs, and industrial and medical machines, along with automobiles, busses, aircraft control surfaces, and hundreds of other applications. Generators who convert mechanical motion into electrical power generation use the same basic rotors, stators, bearings and support structure. Today’s engineering challenges usually include optimizing motor/generator torque, power, efficiency, size, weight, and other performance parameters.

Motor, drive, controls

For electric motors, the specific applications determine the parameters to be optimized. Almost all motors are driven at constant speed, variable speed, or start-stop motion. The increasing emphasis on higher power efficiency leads to variable speed electronic drives being used to achieve higher power efficiency across a wider range than constant speed applications. Developing motion systems that achieve precise positioning capability usually requires motors with high peak torques and smooth velocity and torque motion down to zero speed. The power and control electronics provides a key component to the overall motion control or mechatronics system that includes motor, drive, and control elements.

South Korea’s Electric Research Institute (KERI) has been building various transverse flux motors for more than 10 years.Five popular generic types of electric motors are the universal brush dc, variable or switched reluctance, ac induction, and electronically controlled brushless synchronous or permanent magnet (PM) synchronous motor. The mature universal motor is a wound field motor that can be driven with ac or dc input voltage. It suffers from lower power efficiency. The brush dc motor in wound field and PM configurations has a limited operating life due to its mechanical commutation system.

New technology developments are primarily limited to the reluctance, induction, and brushless PM synchronous motor systems. More recently, combinations of these three motor technologies have also emerged.

Permanent magnet motor

The permanent magnet electric motor has the highest intrinsic power efficiency and leads the other motor technologies in its wide range of new technology candidates. The brushless permanent magnet synchronous motor (PMSM) has many names, including brushless dc motor, brushless PMAC motor, and electronic controlled motor (ECM).

Today’s PMSMs used in a wide range of applications have their magnets located on the cylindrical rotor surface. The latest new products in the servo positioning world have moved toward buried magnets in cylindrical spoke and interior permanent magnet (IPM) configurations. These buried magnet products incrementally increase torque or reduce size and weight in various precision positioning motion systems. Theses servo motors are finding use in machine tool, robots, and semiconductor equipment.

Axial flux motors

The transportation industry in the form of electric bicycle, scooter, motorcycle, and automobile is the target for new PMSM technology. Two excellent examples of new magnet locations are embodied in the axial flux and transverse flux PMSMs.

The axial flux PMSM (figure) has a unique disk shape that develops more torque than conventional cylindrical-shaped radial flux PMSMs. Its unique configuration fits into the center of drive wheels of most types of vehicles.

Axial flux motor provides high torque and low motor shaft speeds that eliminate the need for expensive gear boxes in many applications. The re-emergence of hybrid or electric driven vehicles has fostered a technical reassessment of axial flux motors for use in traction applications.

There are two major axial flux configurations: the internal PM rotor between two stator windings and the Torus that uses two rotors surrounding the nonmoving stator. The internal PM rotor is its most popular configuration. Transportation companies lead the research efforts along with many treatises created by university professors from around the world in evaluating, designing, and using these motor types. Chinese motor companies are making high volumes of hub axial flux motors for electric bicycles.

Our recent recession killed many of these start-up companies using in hub axial flux motors, but KLD Energy Technologies of Austin, Texas, is providing its 5 kw version axial flux in hub motors to scooter manufacturers. YASA Motors of Abington, UK, has developed its axial flux motors for larger vehicles using a slotless or yokeless stator to produce over 60 Nm (44 lb-ft) @ 3600 rpm (25 kw) and achieve a peak power efficiency of 96%. Almost all axial flux motors use the high-energy Neodymium-Iron-Boron magnets.

A more unique configuration of an axial flux PMSM is the NovaTorque (Sunnyvale, CA) PMSM. This axial flux PMSM has an axial length longer than its radial diameter. The NovaTorque rotor has a pair of conical hub assemblies consisting of ferrite magnets embedded in soft magnetic material in an IPM configuration. This configuration allows the low-cost ferrite magnets to achieve motor performance that matches or exceeds rare earth (Neodymium) magnets.

The rotor hub assemblies are positioned at each end of the rotor, and the motor flux flows straight (parallel to the shaft) through the axially oriented field poles of the stator. The conical-shaped rotor hub surfaces create a larger air gap area and resultant improved torque. NovaTorque’s first product, a 3 hp PMSM axial flux motor under the brand name Premium Plus+, develops 159 lb-in (18 Nm) @ 1800 rpm. NovaTorque’s industry focus is the fans, pumps, and compressors used in heating, ventilation, and air conditioning refrigeration (HVACR) products.

Transverse flux motors

The transverse flux motor possesses a complex magnetic circuit. While both radial flux and axial flux motors can be simulated with two-dimensional FEA and more direct mathematic models, the transverse flux motor requires three-dimensional FEA models due to its three-dimensional (3D) magnetic circuits. A ring-shaped stator winding is surrounded by a number of U-shaped magnetic elements. While the transverse flux motor was invented in 1896 by W.M. Morday, the applications that need its enhanced performance capability are emerging slowly due to its complicated structure and extra cost. The development of Neodymium magnets and soft magnetic composite materials has allowed Landert Motoren of Biilach, Switzerland, to develop a family of smaller transverse flux motors, the MDD1 series, with rated torque ranging from 3.3 Nm to 10 Nm @ 300 rpm (100 watts to 300 watts). Applications include rotary tables and other industrial machines.

South Korea’s Electric Research Institute (KERI) has been building various transverse flux motors for more than 10 years. Its mechatronics group has developed rotary and linear versions. Material transport systems were developed up to 1120 lbs-force (5000 N). The transverse flux motor can achieve a very high torque and power density along with a higher manufacturing cost. Its use is currently limited to special applications.

Hybrid cylindrical motors

The radial flux cylindrical motors are also developing new motor technologies by integrating permanent magnet (PM) with variable reluctance and PM with ac induction motors.

QM Power is the best example of a combination of motor technologies. The new QM Power Parallel Path Magnetic Technology (PPMT) combines VR and PM technology. There are two flux patterns developed and sharing the same motor magnetic elements, one from the two PMs and the other from the VR rotor-stator winding configuration. QM Power reports that magnetic force can typically be tripled resulting in a 30% increase in power density and a similar boost in peak efficiency. It is a scalable from 100 watts to hundreds of kilowatts.

The PPMT is aimed at both constant speed and variable speed applications including traction drives. PPMT retains higher power efficiency in higher load conditions. It can achieve excellent performance with ferrite magnets.

Another example of hybrid motor technology is the line start ac induction motor that combines a squirrel cage rotor with a PM magnet cage (usually ferrite type) to significantly improve the ac motor’s power efficiency. Lafert Corp. of Venice, Italy, has a family of industrial and commercial line start ac motors ranging from 1 kw to 15 kw with peak efficiency ratings boosted by 5% to 8%.

Simulation tools

Many of these “new” motor technologies awaited the development of new drive and control electronics, new magnets, and new insulation materials. New simulation tools aid the design of these new motor technologies.

The need for higher torque density, power density, and energy-efficiency motors and generators matches the need for new hybrid and electric vehicle drive motors, new more efficient generators, and smaller and more efficient smart HVACR products. Product cost versus motor and generator performance must be carefully matched to applications needs.
