In-wheel house: Protean Electric’s in-wheel drive system nears production

When Protean Electric begins production of its Protean Drive in-wheel electric drive system later this year, it could mark the stirring comeback of the wheel hub motor, a concept that’s been more than a century in the making.  Electric wheel-hub motors date all the way back to 1884, and none other than Ferdinand Porsche used… Read more »

EVs: the Holy Grail of multiphysics

Sandeep Sovani on the evolution of computer-based engineering simulations. Before actually creating any physical prototypes, engineers build a three-dimensional virtual model of a component, and can use computer simulations to test how the design will perform in the real world. Computer-based engineering simulation early in the development process allows them to refine and validate designs… Read more »

Japanese engineers develop heat-resistant electric aviation motor

The electric airplane has moved a step closer to reality, as Nippon Kayaku Co. and the Japan Aerospace Exploration Agency (JAXA) successfully developed a motor coil that can maintain its maximum power more than two times longer than a conventional model. One of the challenges in designing an electric aircraft is that it must maintain… Read more »

VIDEO: GM begins building Spark EV electric motors in Baltimore

GM claims to be the first US-based automaker to manufacture electric motors and drive units in America, as it began producing these components for the new Chevrolet Spark EV at its Baltimore Operations plant in White Marsh, Maryland. The design of the motors was refined at a pilot facility in Michigan. “The era of using… Read more »

Two new in-wheel electric drive systems unveiled

In-wheel electric drive systems are a hot topic these days. Mounting the electric motor and power electronics within a wheel assembly can improve efficiency, save space and give automakers more flexibility in body design. This week, two leaders in the field introduced new in-wheel offerings. Protean Electric announced the debut of its production in-wheel motor… Read more »

Driving drivetrain development: Schaeffler North America’s VP and CTO on the future of electric drive

  Jeff Hemphill talks eAxles, two-speed transmissions, in-wheel motors and more.  For multinational companies with thousands of employees, collaborating can be a challenge. In 2011, the Schaeffler Group found that divisions from their three product brands – INA, LuK and FAG – were working on different electrification and renewable topics without really talking to each… Read more »

A closer look at switched reluctance motors

The electronically-switched reluctance motor – often shortened to the switched reluctance motor, or SRM – has been gaining in popularity over the last decade because it is simple, robust, and arguably the least expensive of all motor types to manufacture. The reasons for the relatively late blooming of the SRM – the first reluctance motor… Read more »

GE scientists build a greatly improved traction motor for EVs

Engineers at GE Global Research recently tested a prototype Interior Permanent Magnet traction motor that is more powerful, more efficient and less costly than the best motors on the market today. The new motor can also run at a higher temperature, eliminating the need for a dedicated cooling loop.  GE’s prototype operates at a peak… Read more »

ArcelorMittal announces new electrical steel products for EV motors

  As EV production ramps up around the globe, companies are developing ever more components and materials optimized for use in electric and hybrid vehicles. At this week’s Coil Winding, Insulation and Electrical Manufacturing trade fair in Berlin (doesn’t that sound like a glamorous event?), steel giant ArcelorMittal unveiled a range of electrical steel products… Read more »
