GM Unveils New Line-Up of Motors for Its EV Program

Interesting info, does anyone know where Ford is with regard to its motor development/sourcing? Developing its own versus buying from the outside should become a core competency for Ford going forward:

General Motors today unveiled a family of three motors that will do the grunt work when it starts rolling out its next-generation BEVs, starting with the GMC Hummer, later this year. While it might be a stretch, you can think of then as electrified alternatives to today’s 4-, 6- and 8-cylinder internal combustion engines.

All three of the new motors were developed in-house, much like the company’s new Ultium batteries, said GM president Mark Reuss, during an event on Mackinac Island, Michigan on Tuesday.

The new motors include:

  • A high-performance DC permanent magnet design capable of making 255 kilowatts, or 347 horsepower. It will be used in both front and rear locations on vehicles like the new GMC Hummer EV which will pair three to deliver more than 1,000 hp;
  • A slightly smaller permanent magnet motor making 180 kW, or 245 hp. It will be used in less performance-oriented applications but can be paired with both the 255 kW motors as well as;
  • A 62 kW, or 84 hp, AC induction motor that can be used in small, low-performance vehicles. This motor also can be mounted on a vehicle’s rear axle and paired with one of the bigger, permanent magnet motors to create an all-wheel-drive system.
  • The two larger induction motors, GM noted in a statement, were “designed with the aim of minimizing reliance on heavy rare earth materials.”
