PURPOSE:To improve the insulating property between coils and to reduce the size of an end bracket by providing slots of six times of the number of poles, and containing 6, 4 slot pitch coils and 3 slot pitch coils in a special position relationship. CONSTITUTION:In a motor having stator coils of 2-phase windings, 6P pieces (P is the number of poles) of slots 3 are formed, main coils 4 contain concentrically winding coils made of 6 and 4 slot pitches on odd number of poles of the pole number P and 3 slot pitch coils on even number of poles adjacent to the 6-slot pitch coil, and are connected in series. Auxiliary coils 6 of similar configuration is disposed at 90 deg. of an electric angle from the center of the pole of odd number of the coils 4 to form discontinuous portion of the coil end. An end bracket 10 is mounted on the discontinuous portion. |
