PROBLEM TO BE SOLVED: To provide a claw-pole motor that allows a smooth change in a composite magnetic field into which a plurality of magnetic fields are combined.SOLUTION: A claw-pole motor includes: a plurality of teeth 21 to 26 that are aligned in a rotational direction of a mover 8 while forming a pole face 2a of a stator 2; yokes 31 to 36 that are arranged so as to face the respective teeth 21 to 26; magnetic path formation walls that, together with the teeth 21 to 26 and the yokes 31 to 36, form slots which communicate with each other in the rotational direction of the mover 8, while connecting the teeth 21 to 26 and the yokes 31 to 36; and four coils 51 to 54 which are partially housed in the slots and to which AC voltage of three phases with a 360°/3 phase difference between each other are applied. The teeth 21 to 26 are divided into positive-phase teeth 21, 23, and 25, and negative-phase teeth 22, 24, and 26, that have magnetic fields, with different directions, generated by the coils 51 to 54 by being connected to the respective yokes 31 to 36 by the magnetic path formation walls at different positions. |
