Protean Electric introduces production in-wheel motor at SAE World Congress; 25% increase in peak torque
The motors reside in the space behind the wheel. Protean’s new production motor provides a 25% increase in peak torque compared with the previous generation’s design and can deliver 1,000 N·m (735 lb-ft) and 75 kW (100 hp).
Other features of Protean’s in-wheel motors include:
Mass of only 31 kg (68 lbs) per motor.
Up to 85% of the available kinetic energy to be recovered during braking.
Fuel economy improvements up to 30% in hybrid configurations, as compared to the existing vehicle, depending on battery size.
Protean 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.
Protean Electric is presenting a paper at the World Congress: “Using Vehicle Simulation to Investigate Controllability”.
