ことを特徴とするアクチユエータ。 A casing, an output shaft rotatably mounted within the casing, a rotor having a main permanent magnet fixed to the outer periphery of the output shaft, and a plurality of electromagnets spaced apart in the circumferential direction and fixed within the casing. When the rotor is driven, at least one of the plurality of electromagnets facing the main permanent magnet generates a repulsive magnetic field of the main permanent magnet, and a stator located at a rotation destination of the main permanent magnet generates a repulsive magnetic field of the main permanent magnet. The electromagnet is provided with magnetic field switching means for selectively exciting the plurality of electromagnets so as to generate an attractive magnetic field of the main permanent magnet, and the direction of the magnetic field is set on both sides of the main permanent magnet in the circumferential direction. An actuator characterized in that an auxiliary permanent magnet is provided that is set in a direction opposite to the direction of the magnetic field and generates a repulsive force in the rotational direction of the rotor between the magnet and the selective excitation electromagnet.
