Internal permanent magnet electric motors

Our EM-PMI motors are available with power capacities up to 1,000 kW and can function as traction motors in heavy machinery, propulsion motors in marine applications, or variable-speed generators for hybrid vehicles or marine vessels.

Features and benefits

  • Compact and robust structure 
  • High efficiency throughout the operation range
  • Liquid cooling with water/glycol mixture
  • Low coolant flow required; high allowed coolant temperature
  • IP65 enclosure class to maximize reliability; IP67 enclosure class available in some machines
  • Multiple mounting possibilities
  • Capable of producing high starting torques (instant torque to non-moving wheel)

Applications

  • Traction motors for off-road machines
  • Propulsion motors and generators for marine vessels
  • Variable-speed generators for hybrid vehicles and marine vessels
