FS225 permanent magnet motor

FS225 permanent magnet motor

As with all our electric motors, the FS225 is adapted to customer requirements and if required can be upgraded with additional components.

Owing to the low losses, machines can be constructed very compact in surface- and jacket-cooled versions. The efficient cooling permits a high degree of protection against dirt penetration and water ingress.

The efficiency and the high torque density support the economical use of the driven machine, thus contributing to low life cycle costs and improved operational productivity of the machines.

Overview of advantages

  • High efficiency and torque density
  • Compact design
  • Impressive smooth operation
  • Low life cycle costs
  • Efficient surface or jacket cooling
  • Safe protection against dirt penetration and water ingress

Innovative technology as basis for success

  • Maximum performance thanks to buried magnets
    With the storage of the magnets in the rotor stack, the machine can reach its maximum power in a broad speed range and even in the extended field-weakening range.

  • Efficient impregnation
    The VPI impregnation procedure and the use of low loss lamination material form the basis for the high power density of the permanent magnet machines.
