A fixed position rotary actuator comprising: a stator coil that is stopped at an excitation fixed position separated by a predetermined angle with respect to the fixed position;
a mating groove drilled in the stator-side magnetic pole piece; a positioning pin fitted into the mating groove; and a locating pin drilled at a rotor position opposite to the mating groove of the stator when the rotor is in the central fixed position. a positioning recess, and when the power to the stator coil is cut off when the rotor is in the central position, the positioning pin is attracted to the rotor side and stops between the recess and the play groove to position the rotor, and the stator A fixed position actuator characterized in that when the coil is energized, the positioning pin moves from the recessed portion to the side of the play groove, allowing the rotor to rotate toward the fixed excitation position.
