Magic The "magic" can be seen with EXRO's simulation results for induction motors. As Sandy highlighted, EXRO 'can make an induction motor do everything a Permanent Magnet (PM) can do.'
As I understand it, induction motors do not employ rare earth magnets, which can contribute up to 50% of a motor's cost. They do not provide as much torque as a PM motor, so they typically are used as secondary motors for speed. If you can make a cheaper, induction motor do the same job as a PM motor, then that is innovative.
Sue recently talked about how its simulation results were instrumental in EXRO being selected as the Innovation Project partner. This is what the simulation results demonstrated for an induction motor (from EXRO's White Paper "Improving EV Cost, Efficiency, and Performance"):
"In series mode, the machine produces 18% more torque while in parallel mode, the machine generates a staggering 70% more power at 10,000 rpm. The machine also exhibits an expanded +96% efficient operating zone."
Impressive!...significantly higher torque and power across the entire speed range.
