A motor — or a generator — requires some normal magnets and some electromagnets. The usual arrangement is to have a brushed commutator that both powers the electromagnets and switches t… ...

While the all-wheel drive Blazer EV also gets a rear induction motor, the rear-wheel drive model, powered by the larger, 102-kWh battery, gets a permanent-magnet synchronous rear motor instead.

That motor is a permanent magnet synchronous reluctance motor, and it's both more efficient and more powerful than the induction motor that used to sit at the front of Models S and X. Total system ...
