Compact torque motors for engine controls with high torque and dynamics

torque motor

The torque motor is a rotary brushless actuator with a non-contact position sensor and no gears. The torque motor can deliver peak torque values up to 1.5 Nm with a very short positioning time typically below 100 ms. Additional features such as a return-to-zero spring and sensor can be integrated in a very compact footprint.


Simple, robust and extremely reliable, the torque motor is benchmark in terms of service life for powertrain applications in passenger cars and commercial vehicles.

Torque motors overview:

travel angle: up to 75 °
response time: < 100 ms
sensor signal: 0.5 to 4.5 V
