Abstract
An electrical actuator limits the speed of the electric motor which controls the hydraulic pump of the actuator, during the opening of a pressure relief valve. To this end, the electrical actuator applies an auxiliary set-point speed value to the electric motor to avoid damage that may be caused by overheat at the actuator.
