Mitsubishi makes minuscule motor with integrated inverter

Mitsubishi Electric Corporation has developed a prototype EV motor drive system with a built-in silicon-carbide inverter that it claims is the smallest of its kind. As EVs require large spaces to accommodate their battery systems, Mitsubishi sees a strong need to reduce the size and weight of motor systems to leave a decent amount of… Read more »

DOE announces $50 million for vehicle R&D funding, releases plug-in progress report

The DOE will award $49.4 million in new funding for projects that accelerate research and development of new vehicle technologies. The announcement identifies 13 areas of interest, of which 7 are described as “critical technologies” to meet the EV Everywhere Grand Challenge, which has a goal of making EVs more affordable and convenient to own… Read more »

DOE offers $10 million in research funding for batteries, motors and power electronics

If you’ve got an idea for cheaper, lighter, safer or more durable batteries or electric powertrain components, you may be eligible for a piece of a new $10 million pot of research funding. The DOE’s Vehicle Technologies Office (VTO) has issued an Incubator Funding Opportunity Announcement (FOA) for projects that address any of several “areas… Read more »

NC State University to lead new institute for next-generation power electronics

President Obama has announced the selection of a consortium of businesses and universities to lead a manufacturing innovation institute for next-generation power electronics. Last May, the President committed $200 million in federal funding to three new regional hubs, designed to bridge the gap between applied research and product development, and launched a competition to select… Read more »

Protean and VW Chinese joint venture partner to produce new electric drivetrain

In-wheel motor developer Protean Electric is partnering with FAW-Volkswagen in China to develop a new electric propulsion system. FAW-VW will create a new rear-wheel drivetrain for an EV based on the new Bora compact sedan, using two Protean in-wheel motors. “This is a two-phase project that will capitalize on the torque and packaging freedoms that… Read more »

Chrysler partners with McMaster University to develop advanced electric powertrains

Chrysler has entered a five-year, $18.2 million partnership with McMaster University, with funding support from the Canadian government, to develop next-generation electrified powertrains. Chrysler Group will invest $9.25 million in cash and in-kind contributions, with an additional $8.93 million coming from the Natural Sciences and Engineering Research Council of Canada (NSERC). 20 Chrysler engineers and… Read more »

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 »
