Mahle's highly efficient new electric motor ditches rare earth metals altogether, instead using contactless induction to feed power to coils in the rotor Mahle 1/4 Mahle's highly efficient new electric motor ditches rare earth metals altogether, instead using contactless induction to feed power to coils in the rotor Mahle Mahle 3/4 A wireless transmitter sends power to the rotor, using an alternating field that's converted into direct current for the magnet coils Mahle 4/4 The ability to continuously tune the magnetism of the coils in the rotor has enabled Mahle to make this a super-efficient electric motor across all operating speeds, particularly excelling at high speeds
