General Motors’ new lineup of electric models will feature three electric motors. GM will mix and match the motors as each model requires.
The company is building the electric models on GM’s Ultium battery-powered platform. And they represent the next step in GM’s overall strategy. The company hopes to claim the top spot in the electric vehicle market.
Moreover, the electric motors come in three power levels, Fox News reports. There’s a 180-kilowatt motor. That’s for front-wheel-drive applications. There’s a 255-kilowatt motor. It can be adapted for the front or rear. Then there’s a 62-kilowatt auxiliary motor.
Motors Use a Design That Downplays Rare Earth Minerals
General Motors engineered the electric motors in-house. Also, they come with new power control units. And, in case you were wondering, there is a super high-kilowatt option. The GMC Hummer EV will use three of the 255-kilowatt motors to get to its 1,000 hp rating.
The more powerful motors rely on a permanent magnet design. That cuts back on the need for rare earth minerals. The smallest motor, meanwhile, is an induction motor. A GM spokesman told Fox that it can help get the vehicle unstuck. And it can be disengaged to improve efficiency.
All three of the motors were created as part of a scalable family, per GM Authority. They have similar design principles. They also have comparable tooling and manufacturing strategies. The goal? To decrease the number of parts required to bring the motors to market.
General Motors Is Pivoting to EVs With a Vengeance
Meanwhile, GM President Mark Reuss recently presented the three new electric motors at the 2021 Mackinac Policy Conference. He also spoke to their place in GM’s overall electric strategy.
“Twenty years of electric drive system development and more than 100 years of high-volume vehicle engineering are helping GM pivot quickly from conventional vehicles to EVs,” Reuss said. “Our vertical integration in this space encompass[es] both hardware and software. [It] helps give us control over our own destiny and a significant competitive advantage.”
To his point, GM also unveiled new software used to run the electric hardware. The company’s Ultium Drive software relies on computer-assisted and virtual engineering. And it can be reused in multiple applications. The upshot: faster go-to-market times and an expansion of GM’s EV portfolio.
GM says its electric hardware weighs in at half the mass and volume of present equivalents. Plus, it boasts up to 25 percent more capability.
