During its participation in the 35th International Electric Vehicle Symposium (EVS) in Oslo, Vitesco Technologies presented an electric motor without rare earth metals, specifically designed for high ranges, faster driving on highways, and thus for future long-distance electric vehicles. The system is called externally excited synchronous electric machine (EESM) and is an alternative to permanently excited synchronous machines (PSM), currently a standard in vehicle electrification.

The advantages of an electric motor without rare earth metals

Especially at high speed, EESM seem to be more efficient compared to PSM. More into technical details, instead of magnets, the rotor here has coils. In addition to efficiency at high speeds, this offers the advantage of avoiding the prices for permanent magnets, which have now risen to a 10-year high. In addition, the CO2 footprint of the drive is reduced by the portion attributable to rare earth mining, which can have a positive impact on product sustainability over its life cycle.
