One example of this development is our SSM or Separately-Excited Synchronous Motor. With the replacement of permanent magnets with rotor windings, we have discovered a substantial reduction of our CO2 footprint during production and our reliance on rare earth materials. Using strategic rotor slots, slot bodies and potting, reducing our carbon footprint is not at the expense of rotor strength. With dedicated rotor cooling channels, the rotor windings are cooled from the slot bodies, closest to the thermal losses, producing higher efficiency.
To further improve efficiency, inductive transmitters are used rather than mechanically lossy brush transmitters. Unlike a brush system, our inductive system is highly efficient, reduces packaging space, and is not limited to a dry environment. While remaining cost effective, Schaeffler PSM, ASM, SSM, and HPM motors provide a solution for a more efficient, economically packaged, and sustainable electric motor.
