ARPA-E awards $27 million for power electronics research

The DOE’s Advanced Research Projects Agency-Energy (ARPA-E) has selected 14 projects to receive $27 million in funding to support the development of next-generation power conversion devices. These devices, which convert electrical energy from high to low voltages, are critical to all electronic devices, and represent a key enabling technology for electric vehicles.  The DOE’s talent… Read more »

A closer look at back electromotive force

Why motors generate and generators motor In a previous article I took a closer look at regenerative braking, and mentioned an old engineering saying that every motor is a generator and every generator is a motor (along with the caveat that some are more suited to the opposite purpose than others). This time around I’ll… Read more »

BRUSA offers electric drive components in 750-volt versions for commercial vehicles

The Swiss firm BRUSA is now offering its electric-drive components, including motors, controllers, power electronics, battery packs and chargers, in 750-volt versions, which are designed for commercial vehicles and applications demanding high output. Increasing the voltage allows the current to be reduced with no loss of performance. This means that cables can be thinner and… Read more »

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 »

President Obama proposes innovation institutes to target high-tech manufacturing

As it becomes clearer that the economy of the future is not so much a post-industrial economy as a high-tech manufacturing economy, US manufacturers have added about 500,000 jobs over the past three years. In order to “build on this momentum with a comprehensive agenda to invest in American manufacturing,” the Obama Administration has announced… Read more »

McLaren P1 delivers instant torque with twin power plants

The McLaren P1 looks like it belongs on a race track, but its maker hints that this “production-ready version” might someday be an option for your daily commute. The super-PHEV, which will make its world debut at next week’s Geneva Motor Show, uses the combined force of a V8 gas engine and an electric motor… Read more »

Siemens and Semikron increase collaboration on EV power electronics

The Siemens Drive Technologies Division has signed an agreement with Semikron International, under which Siemens will take over Semikron’s VePOINT subsidiary, and the two companies will increase their cooperation in the field of EV power electronics. VePOINT’s technology is meant to complement the Siemens range of products by adding systems with attractive power densities and… 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 »
