General Motors recently spent a lot of time talking about the capabilities of its upcoming Ultium battery technology, but has said a lot less about the motors these cells will power. That changed on Tuesday when the company detailed its new Ultium Drive motors. With today’s announcement, the series consists of three different models: a 180 kW front-wheel drive model, a 255 kW front-drive and rear-wheel drive variant and a 62 kW all-wheel drive assist motor. . The first two models are GM permanent magnet motors designed in an attempt to reduce its reliance on heavy rare metals.
The company didn’t talk about the specific torque and power density characters of each engine, but said they should deliver “excellent” performance on those fronts. He also revealed that the 2022 Hummer EV will include three of the 255 kW models. GM says they will allow the vehicle to produce a combined torque of 11,500 ft / lb and accelerate from zero to 60 miles per hour in about three seconds.
GM says its engineers designed the engines with scalability in mind. Each can be made using similar manufacturing tools and techniques. He also found a way to integrate components like the inverter directly into motors, a feat the company says should cut costs and simplify manufacturing.
