Rotary actuator is a device which enables generating rotary motion at certain velocity and torque. In this master’s thesis we found a solution for simulating torsion load for rotary actuator testing. We tested chosen brake in different environments and confirmed its suitability. We particularly focused on testing at extreme temperatures. We also analysed potential improvements in order to achieve even better results. The changes we made resulted in better torque characteristics, especially at low temperature.
