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.
The plant is expected to start production in 2024. The finished
magnets will be delivered to facilities building EV motors for
GM's Ultium-powered EVs. Currently, the two companies are
working on the plant location and finalizing definitive agreements,
expected in early 2022.
Magnets are at the heart of an EV motor, notes GM. Within
the motors, an electric coil generates a magnetic field to push
against strong magnets, creating the torque that propels a
vehicle's wheels. A GMC Hummer EV powered by GM's Ultium
Platform, for example, may have as many as three motors with
up to 11,500 lb-ft of torque (15,590 Nm). All of this power is
available to the driver on demand, allowing the vehicle to accelerate
0-60 mph in just three seconds.
GM revealed recently more details about its group of three
all-new motors that will power the Ultium-based EVs. Designed
by GM, the 180-kilowatt front-drive motor, 255-kW rear- and
front-drive motor and 62-kW all-wheel drive assist motor are part
of the company's Ultium Drive system. All three motors were
calibrated in-house to ensure the highest level of performance in
Ultium-based EVs. The motors were built as a scalable family,
sharing design principles as well as similar tooling and manufacturing
strategies.
" 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, " said Marc
Reuss, president at a conference in Detroit. " Our vertical integration
in this space, encompassing both hardware and software,
helps give us control over our own destiny and a significant
competitive advantage. "
The 180- and 255-kW units are permanent magnet motors
designed with the aim of minimizing reliance on heavy rare earth
materials while the 62-kW unit is an induction motor. All are
expected to offer excellent torque and power density, enabling a
wide spectrum of vehicle types, from performance cars to work
trucks. As many as three electric motors can be used in one

EV - variations of the 2022 GMC Hummer EV will feature three
separate 255-kW motors, yielding a GM-estimated output of
1,000 horsepower.
An example of how some of the investment unfolds is taking
place at a GM components plant in Lockport, New York...
