同期電動機。 a disc-shaped rotor magnet having different magnetic poles alternately in the rotational direction of the rotor; a rotating shaft that is inserted through the center of the rotor magnet and rotates together with the rotor magnet;
A synchronous motor includes a stator electromagnet having a plurality of magnetic poles arranged at fixed positions opposite to the magnetic poles of the rotor magnet, and generates an alternating magnetic field in the magnetic poles of the stator electromagnet to cause the rotor to rotate synchronously. The bush is held between a bush fixed to the rotating shaft with the rotating shaft inserted through it, and a mounting step formed on the circumferential surface of the rotating shaft that is attached to the rotating shaft with the rotating shaft inserted through it. The washer is equipped with a retaining spring made of a plate spring that holds the rotor magnet between a washer attached to the bushing and a holding step formed on the circumferential surface of the bushing. A synchronous motor that is in sliding contact with the end face of a bearing that is inserted through it.
