PROBLEM TO BE SOLVED: To provide a motor in which the eddy current of a field magnet can be reduced.SOLUTION: A rotor 10 and a stator 20 face each other via an air gap in the radial direction. Teeth 211 are provided in the circumferential direction while spaced apart from each other. A yoke 212 couples the teeth 211 magnetically on the side opposite from the rotor 10. Field magnets 22 are arranged in the every other adjoining field slots 213a, out of a plurality of slots 213 formed between each other teeth 211 in the circumferential direction, while facing the pole faces of the same polarity each other in the circumferential direction. A field winding 23 is wound around the teeth 211 in the field slots 213a. An armature winding 24 is wound around the teeth 211, in the armature slots 213b other than the field slots 213a, out of the slots 213. Inductance of the field winding 23 is larger than that of the armature winding 24.SELECTED DRAWING: Figure 1 |
