A motor for an electrohydraulic actuator (EHA). The motor comprises a rotary shaft for rotation about an axis (R), a rotor attached to the rotary shaft and rotatable therewith, a stator surrounding at least a portion of the rotor and a liner disposed between the rotor and the stator. The liner defines an axially extending chamber around the rotor for retaining a fluid between the rotor and the liner. The liner comprises a tubular body having an open end and a closed end. An EHA comprising the motor is also claimed.
