Abstract
An electromechanical actuator for use in a hydraulic braking circuit of a vehicle comprises an electric motor having a stator and a rotor, and a linear actuator that is located within the motor. The linear actuator comprises an elongate shaft having a screw part at one end carrying an external thread that extends along a portion of the shaft, and a fixing part at the other end shaft, the linear actuator further comprising a drive nut that surrounds the screw part of the shaft and is located at least in a retracted position inside the enlarged bore of the first portion of the rotor body, the drive nut and being connected to the screw part. The rotor body is secured relative to the stator by a bearing assembly that is fixed to the second part of the elongate rotor body, the other end of the rotor body being otherwise unsupported and overhung from the bearing assembly.
