Example Torsion Test Rig

The torque motor converting hydraulic into mechanical energy is the core of any torque test rig. Based on our extensive know-how, we can build solutions tailored to the requirements of your test rig in terms of rotational speed and torque. Our components allow testing with static and quasi-static load spectrums as well as dynamic torque induction. High performance density is a characteristic feature of our torque motors, making them suitable for almost any testing condition.
