Torque Motor

Why you might need the Torque Motor

These contactless rotary actuators cover various powertrain applications, for more efficient and cleaner cars, as well as medium duty trucks.
Very compact and cost-efficient Sonceboz Torque Motors are ideal for fast positioning of air admission and exhaust valves. Their robustness and reliability in harsh environments ensure their successful integration in on-engine applications.
These simple, brushless DC rotary actuators are controlled by a standard H-bridge integrated in the Engine Control Unit and offer a 75° angular stroke.

The existing portfolio covers peak torques between 0.7 Nm and 2 Nm. Waterproof designs and fail-safe integration are available.
