Magnetic induction motors
Web22 jul. 2024 · The rotor has neither magnets nor windings and suffers virtually no power losses. And because there are no magnetic forces in the rotor, maintenance is as straightforward as with induction motors. ABB’s SynRM was launched in 2011 with an IE4 efficiency class, available at first for pumps and fans, and now available for all applications. Web12 mei 2024 · Today Mahle, a German auto parts company, unveiled a motor that’s free of both rare earths and of physical contact. Power is beamed into the rotor wirelessly, through induction, by a coil carrying alternating current.
