Magnetic Levitation Motor

HERMANN KEMPER Magnetic Levitation Motors with HERMANN KEMPER magnetic bearings have the following advantages:
  • High speed
  • High efficiency
  • No oil lubrication
  • No mechanical friction
These magnetic levitation motors offer high performance without a gearbox at rotational speeds up to 60,000 rpm and use permanent magnet rotors supported on magnetic bearings to achieve increased efficiency and high torque density.

To simplify integration into a system, the control electronics for the magnetic bearings are seamlessly incorporated into the drive train housing, greatly reducing the field wiring. These design innovations decrease the size and complexity of the machine, improve the dynamic performance, and increase the economic value of the system.
