How to Build EV Motors Without Rare Earth Elements

Cars That Think

Such a massive shift will inevitably mean far greater use of electric traction motors, nearly all of which rely on magnets that contain rare earth elements, which cause substantial environmental degradation when their ores are extracted and then processed into industrially useful forms. research on advanced motors for EVs.

Wuhan University team proposes structure-variable sliding mode control of IPMSM in EVs

Green Car Congress

Researchers at Wuhan University of Science and Technology in China have proposed a control method based on a speed loop structure-variable sliding mode controller (SMC) for interior permanent magnet synchronous motors in electric vehicles. The method combines maximum torque per ampere with a vector control strategy.

Electrostatic Motors Reach the Macro Scale

Cars That Think

It’s a pretty sure bet that you couldn’t get through a typical day without the direct support of dozens of electric motors. For decades, however, engineers have been tantalized by the virtues of motors based on an entirely different principle: electrostatics. The global market for fractional horsepower motors is more than US $8.7
