Abstract
An electro-hydraulic actuator has a master cylinder, an electric motor and an electro-mechanical brake. The master cylinder has a hydraulic cylinder and an actuation piston slidably received within the hydraulic cylinder to vary pressure within a hydraulic circuit. The electric motor is adapted to drive the actuation piston into the hydraulic cylinder. The motor has a stator and a rotor. The electro-mechanical brake is arranged to selectively and releasably hold the rotor with respect to the stator to prevent relative rotational motion there between.
