Synchronous reluctance motors (SynRM)

Do you need IE5 efficiency or a higher power density?

ABB offers two ranges of synchronous reluctance motors:

  • IE5 SynRM motors
  • High Output SynRM motors

Innovation inside

The idea is simple. Take a conventional, proven stator technology and a innovative rotor design. Then combine them with a best-in-class industrial drive loaded with new, purpose-designed software.

Magnet-free design

Synchronous reluctance technology combines the performance of the permanent magnet motor with the simplicity and service-friendliness of an induction motor. The rotor has neither magnets nor windings and suffers virtually no power losses. And because there are no magnetic forces in the rotor, maintenance is as straightforward as with induction motors.
