されてなる1. A winding method in which the number of magnetic poles per pole of one phase of a multi-phase motor is 2 or more, and the winding forming one pole of one phase is composed of two or more types of coils having different coil pitches. Each phase winding is configured by connecting two or more types of winding units in which k coils having the same coil pitch are connected in series, and the winding of each phase is connected. The units are wound in such a manner that the coil pitches are small, and that the winding units having the same coil pitch and the same positioning of each phase have a predetermined phase sequence, and are wound in such a manner that
A winding method for a multi-phase electric motor, wherein each winding unit belonging to each phase is connected so as to form a predetermined number of poles. However, k is the number of poles, and when the winding unit is composed of k coils, the coils are connected so that their polarities are opposite to each other, and each winding unit is composed of k / 2 coils. In this case, the coils are connected so as to have the same polarity as each other.
