High-Speed Motors & Generators

Permanent magnet motors have established major advantages over other types of motors. Synchrony high-speed motors and generators with magnetic bearings have taken the next step forward from previous generations of permanent magnet motors.


Synchrony High-Speed Motors

These oil-less drive trains offer high performance without a gearbox at high rotational speeds. Synchrony motors use permanent magnet rotors supported on magnetic bearings to achieve increased efficiency and high power density. To simplify integration into a system, the control electronics for the magnetic bearings are seamlessly incorporated into the drive train, greatly reducing the field wiring. These design innovations decrease the size and complexity, improve the dynamic performance, and increase the economic value of the system.

Synchrony High-Speed Generators

Due to the nature of permanent magnet motors, the Synchrony drive train can easily be adapted for use as a generator.
