The alternating magnetic field generated in the stator core 3 by the coil 4 causes the permanent magnet rotor 2 to
When the rotation of the permanent magnet rotor 2 starts to rotate, the rotation of the permanent magnet rotor 2 is transmitted to the wheel gear 8 via the worm gear 9 fixed to the rotor shaft 7. During the transmission, the worm gear 9 receives a reaction force from the wheel gear 8. will receive. Now, if the direction of the teeth of the A-mugia 9 is to the left as shown in the figure, when the permanent magnet rotor 2 starts to rotate in the direction, the magnetic absorption force causes it to be positioned in the center of the stator core 3 before rotation. The permanent magnet rotor 2 moves in the thrust direction shown by arrow A' (to the left in FIG. Since the swinging piece 11 is brought into contact and pressed to swing the swinging piece 11 against the elastic force, the contact state between the swinging piece 11 and the fixed piece 12 is released, and the drive power circuit of the motor is turned off. As a result, the permanent magnet rotor 2 stops rotating in the backward direction, and the reaction force from the wheel gear 8 no longer acts on it, so the permanent magnet rotor 2 returns to its original neutral position due to the magnetic attraction force, and swings. Piece 11 and fixed piece 12 come into contact again, current flows through the circuit, and rotor 2 is restarted.

The rotor 2 rotates continuously in the B direction.

耐えることができるという利点を有するbのである。Effects of the Invention As described above, according to the present invention, a worm gear that meshes with the wheel gear is fixed on the rotor shaft, and the reaction force that the worm gear receives from the wheel gear causes the rotor to move inside the bearing according to the direction of rotation. A permanent magnet synchronous motor that can freely move in the thrust direction is provided with an electric contact on the motor body that opens and closes the drive power circuit of the motor, and the opening and closing of this electric contact is linked to the movement in the thrust direction. As a result, the permanent magnet rotor can be reliably and continuously rotated only in a predetermined direction, and since there is no part I that comes into mechanical contact with the rotor during continuous rotation, it is possible to rotate the permanent magnet rotor even at high speeds. It has the advantage of not generating noise and being able to withstand continuous rotation.
