What is a torque motor?

Torque motors are permanent-magnet direct drive motors that rotate along an axis. They can be used wherever a rotary movement is required and offer numerous advantages over conventional servo drives.

Our torque motors are extremely compact, provide an extremely stiff drive train, eliminate the need for time-consuming mounting procedures, are virtually maintenance-free, and can be integrated directly into the machine structure, while the spacious open inner diameter enables wire and cable feedthrough. To top things off the entire series comes with completely sealed stators and integrated temperature protection and measurement sensors.

Required torque and available space help determine the diameter and width of the motor. Motors can be very slim but large in diameter (large axles and turntables) or have a ‘height’ close to their diameter, resulting in a compact but high-torque motor.
