The motors that will power GM’s Ultium-based EVs were built as a scalable family, sharing design principles as well as similar tooling and manufacturing strategies. Pictured are the stators of all three motors.
GM’s 180-kW, permanent magnet EV motor will be used for front-wheel drive and all-wheel drive applications.
GM’s 255-kW, permanent magnet EV motor will be used for performance all-wheel drive and rear-wheel drive applications.
GM’s 62-kW induction EV motor will be used in all-wheel drive applications.
The power electronics of GM’s Ultium-based EVs will be integrated directly into the Ultium Drive units, reducing costs, weight and manufacturing complexity while increasing reliability. The inverter and other power electronics like the accessory power module and onboard charging module will reside within boxes such as this inside GM’s Ultium Drive units.
