Synchronous motors are smaller

Rotek synchronous motors have a smaller physical size compared with asynchronous AC motors with the same output power.

Rotek synchronous motors have a smaller physical size compared with asynchronous AC motors with the same output power.

There is no temperature variation between no load and full load torque.

Self-holding torque is applied without electrical power (no brake necessary), and starting torque, unlike asynchronous AC motors is almost the same as the nominal torque.

Thanks to the construction method (permanent magnet rotor) the motor speed is locked into the supply frequency thus maintaining a constant speed under varying load conditions.

The programme has over 60,000 standard variants, with an infinite amount of options for special requirements available on request from OEM Automatic.
