  • increased power density – up to 50% more power than conventional drives
  • highest energy efficiency over the entire range of application
  • extremely compact design possible
  • electric motor with multirotor structure (a stator with four/ six/ eight/ ... rotors)
  • rotors are mechanically coupled via an integrated gear unit – which becomes an integrated part of the motor
  • with four rotors: twice the power of a conventional machine with the same rotor cross-sectional area
  • at the same time less material required for the stator
  • possible as permanent magnet- or reluctance-motor (without rare earth metals)
  • sensorless control possible by means of INFORM® control and thus failsafe and with even reduced volume
  • failure safety due to elimination of sensors
  • enhanced efficiency at lower production costall electric contacts and power electronics can be placed simply at front side, opposite of output side
  • manufacturing with a high degree of automatization possible – and thus further significant cost reduction
