PROBLEM TO BE SOLVED: To provide a coil winding method of a synchronous motor that reduces the amount of labor required for coil winding because the total number of coils can be reduced by winding coils on back yokes. SOLUTION: The synchronous motor 1 has back yokes 4a-4l, which constitute a stator in an annular shape, teeth 5a-5l, which protrude from the back yokes to the rotor side, and a rotor, which is supported rotatably inside the stator. Coils are wound on the back yokes every other slot to cause two teeth 5 forming the slots wound with coils to have reverse polarities in the same phase. COPYRIGHT: (C)2009,JPO&INPIT
