Externally Excited Synchronous Machine
Our latest advancements in Externally Excited Synchronous Motor (EESM) technology have closed the gap with permanent magnet motor torque and power density, as well as with induction motor high speed efficiency. These performance advancements, coupled with the lack of dependence on rare earth materials, provide a competitive advantage when compared to other solutions. Schaeffler EESMs also feature integrated cooling and are capable of high rotational strength. Pair this EESM rotor with our wet brush power transmitter for a complete package.
