LTi - LST motors

Featuring conventional winding technology, the LST motor combines all the advantages of a 6-pole synchronous servomotor. The servomotors have Neodymium permanent magnets in the rotor.

Because of the standardised flange and shaft measurements the motors can be easily combined with gearboxes and other equipment.


The motors are equipped with two-pole hollow-shaft resolvers as standard, but can be supplied with a wide range of encoders such as incremental, sine/cosine, EnDat and Hiperface.

Holding Brake

The motor can be delivered with or without a built-in holding brake. Retrofitting is not possible. The motor length will increase with an installed brake.


Coil temperature is supervised by temperature sensors and reported by potential free contacts.
