Claims

[Scope of utility model registration request]

An AC motor having reluctance torque, a driven member driven by the rotation of the motor, a position detection means for detecting the rotational position of the motor, a sensor for detecting environmental conditions such as temperature, and a and a control circuit that uses a signal to stop the motor and uses a signal from the sensor to drive the motor, and when the motor stops, the driven member is held in a predetermined position by its reluctance torque. A motor actuator characterized by:
