How to Build EV Motors Without Rare Earth Elements
The experimental in-rotor inductive-excited synchronous motor by ZF Friedrichshafen dispenses with rare earth elements by using electromagnets in its stator and rotor.The dilemma is easy to describe. Global efforts to combat climate change hinge on pivoting sharply away from fossil fuels. To do that will require electrifying transportation, primarily by shifting from vehicles with combustion engines to ones with electric drive trains. Such a massive shift will inevitably mean far greater use of ...
