Motor

A motor, comprising:

• a motor bracket;
• a shaft, fixed to the motor bracket;
• a rotor, rotatably supported by the shaft;
• and
• a stator, fixed to the motor bracket inside the rotor and configured to generate a magnetic field for rotating the rotor, and
• the stator comprising:
• a cylindrical body, comprising a plurality of flat surfaces arranged in a circumferential direction so as to surround the shaft, and corner parts located at boundaries between the adjacent flat surfaces;
• a plurality of first teeth, protruding outward from an outer surface of the cylindrical body and having coils wound thereon, and a plurality of second teeth having a greater number of coil turns than the first teeth;
• and
• a plurality of bolt mounting parts, provided on inner surfaces of the corner parts, into which bolts for fixing the stator to the motor bracket are inserted,
• the plurality of flat surfaces being located inside a virtual circle passing through the plurality of corner parts at which the bolt mounting parts are provided,
• the first teeth being formed on outer surfaces of the corner parts at which the bolt mounting parts are provided, and
• the second teeth being formed on outer surfaces of the flat surfaces on opposite sides of the corner parts at which the bolt mounting parts are provided across the shaft.
