PROBLEM TO BE SOLVED: To further reduce variation of a torque of a motor with respect to a stator having a flange portion on the inner end of a diameter direction of the stator core formed by circularly arranging a plurality of split cores.SOLUTION: The stator includes a stator core 6 formed by circularly arranging a plurality of first split cores 3 and a plurality of second split cores 4 inside of a radius direction and including a plurality of tooth portions 3b, 4a and a plurality of slot portions 5, and a distributively wound coil 2 housed in the slot portions 5 of the stator core 6. The first split cores 3 each include a back portion 3a and the first tooth portion 3b. The second split cores 4 each include a second tooth portion 4a, and a flange portion 4b positioned at the inside end of a diameter direction of the second tooth portion 4a. The slot portions 5 are formed between the first tooth portion 3b and the second tooth portion 4a, respectively. Same-phase coils of the distributively wound coils 2 are housed in the slot portions 5 at both sides of circumferential direction of the second tooth portions 4a, respectively. |
