PROBLEM TO BE SOLVED: To provide an electric motor which allows for enhancement of rotation balance, weight balance, and magnetic balance, while suppressing increase in the manufacturing cost, and allows for simplification of the winding work when changing the wire diameter of the winding.SOLUTION: A winding 14 consists of a first coil 15 formed by winding (N/2+α) turns, respectively, between two predetermined slots 13 existing at positions point symmetrical with respect to a rotating shaft 44, where N is the predetermined number of turns of the winding 14 between the predetermined slots 13, A is an integer of 0 or more, and α is set to satisfy α=0.5A, and a second coil 16 formed by winding (N/2-α) turns, respectively, between two predetermined slots 13, similarly to formation of the first coil 15. The wire diameter of the first coil 15 is different from that of the second coil 16. |
