GM Reveals All-New EV Motors

It was at the 2021 Mackinac Policy Conference in Michigan that General Motors President Mark Reuss revealed a group of three all-new motors created to power its Ultium-based EVs.

Designed by GM itself, the 180-kilowatt front-drive motor, 255-kW rear- and front-drive motor and 62-kW all-wheel drive assist motor are part of Ultium Drive. All three motors were calibrated in-house to ensure the highest level of performance in Ultium-based EVs. The motors were built to share design principles as well as similar tooling and manufacturing strategies. The 180- and 255-kW units are permanent magnet motors designed with the goal of minimizing reliance on heavy rare earth materials. The 62-kW unit is an induction motor. 

Let it be known that as many as three electric motors can be used in one EV. For example, variations of the 2022 GMC HUMMER EV will feature three separate 255-kW motors, yielding an estimated output of 1,000 horsepower.
