Protean Electric launches in-wheel electric drive system

May 2, 2013

proteanPROTEAN Electric, the global leader of advanced in-wheel electric drive debuted its production in-wheel motor at the 2013 Society of Automotive Engineers World Congress held in April in Detroit, Michigan, US.

The award winning technology is an integral part of a hybrid powertrain system when paired with a traditional internal combustion engine. It is also powerful enough to be the only source of traction drive in electric vehicles.

The motors reside in the space behind the wheel, producing torque and power exactly where and when drivers need it. Protean’s new production motor provides a 25% increase in peak torque compared with the previous generation’s design and can deliver 1,000 Nm (735 lb.-ft.) and 75 kW (100 hp).

“Protean Electric is ready to enable the global automobile industry as it moves to high volume, low cost hybrid and electric drive powertrains,” said Bob Purcell, chairman and CEO of Protean Electric. “Our system can be applied to current vehicle platforms, retrofit existing vehicles or create all new architectures for the future.”

A winner of last year’s Technology Pioneers Award from the World Economic Forum (WEF), the Protean in-wheel motors features the highest torque density of current leading electric drive systems; a 75 kW (100 hp) peak power and 1,000 Nm (735 lb -ft.) peak torque in each motor; mass of only 31 kg (68 lbs) per motor; fuel economy improvements up to 30% in hybrid configurations, as compared to the existing vehicle, depending on battery size; and, superior regenerative braking capabilities, which allow up to 85% of the available kinetic energy to be recovered during braking.

It has been awarded 27 patents for its unique technology and design, with 84 additional international patent applications pending; and has developed multiple demonstration vehicles, including a Vauxhall Vivaro cargo van, Guangzhou Automobile Industry Group (GAC) Trumpchi sedan, a Ford F150 pick-up truck, and BRABUS full electric and hybrid vehicles, based on the Mercedes-Benz E-Class.
