Abstract:
An electro-mechanical actuator adapted to be connected to an external device for displacing the external device to a predetermined position and maintaining the external device at the predetermined position, said actuator comprising:a housing;means provided in said housing for driving the external device to the predetermined position when said driving means is energized;braking means for maintaining the external device at the predetermined position when said braking means is activated;coupling means for connecting said actuator to said external device, and torque transmitting means operationally engaged between said driving means and said coupling means for transmitting torque between said driving means and said coupling means; and,switching means for generating a first switching signal for energizing said driving means to drive the external device to the predetermined position, and a second switching signal for de-energizing said driving means and activating said braking means when a predetermined time has passed from a moment said driving means is energized, to maintain the external device at the predetermined position.
