Abstract:
An electromechanical actuator, in particular for controlling a brake associated with the laundry drum of a washing machine, comprising:a stationary support structure, an actuator member which is movable relative to the structure and can perform an actuation movement in one direction and a return or release movement in the opposite direction, an electric motor connected to the structure and including a rotor portion which can translate from a first, rest axial position to a second, working axial position as a result of an energization of a stator and against the action of resilient means, a gear transmission which is coupled to the actuator member and can be coupled for rotation with the rotor portion of the motor when the rotor portion is in the working axial position, in order to bring about an actuation movement of the actuator member, and a stop device comprising a movable retaining member which can adopt an inactive condition and an active condition in which it permits and prevents a return of movement of the actuator member, respectively, the retaining member being operatively coupled to the rotor portion of the motor in a manner such that it can adopt the inactive condition and the active condition when the rotor portion adopts the rest position and when the rotor portion adopts the working position, respectively.
