PROBLEM TO BE SOLVED: To provide a dynamo-electric machine which can be made compact in the axial direction of the core.SOLUTION: A dynamo-electric machine includes a field magnet (annular magnet) where S poles and N poles are arranged alternately, a core 22 having a plurality of teeth 22c protruding radially from an annular portion 22b concentric to the axis of the field magnet, and arranged in the circumferential direction of the annular portion 22b, a first phase coil 32 where a plurality of coils 24 (winding portion) straddling two adjacent teeth 22c are arranged, by 1 teeth skip, in the circumferential direction of the annular portion 22b, and a second phase coil 34 where a plurality of coils 24 (winding portion) straddling two adjacent teeth 22c are arranged, by 1 teeth skip, in the circumferential direction of the annular portion 22b, with the teeth 22c on the opposite side from the start-of-winding position of the first phase coil 32 and the axis of the annular portion 22b therebetween, being as the start-of-winding position. |
