Claims

[Scope of utility model registration request]

a rotor having a permanent magnet with multiple front poles in the rotational direction;
The stator includes an excitation coil disposed surrounding the outer circumference of the rotor, and a stator in which a large number of magnetic pole pieces are interposed between the outer circumference of the rotor and the excitation coil and arranged in a protruding direction in the rotational direction of the rotor. A synchronous motor, characterized in that predetermined magnetic pole pieces among a plurality of magnetic pole pieces excited to different polarities by the excitation coil are magnetically short-circuited.
