The invention discloses an arrangement method for number of distribution slots in single-phase, three-phase motor fractional-slot windings. The arrangement method comprises the following steps of: calculating the numbers of slots per phase per pole as follows: q =Z / (2p*m); representing q value in the form of a mixed fraction, making b equal to the integer part of q value, c equal to the numerator of the proper fraction in the q value, and d equal to the denominator of proper fraction in the q value, namely q =b+c / d; arranging a first line list and a second line list, then determining the cycle number sequence and the cycle period number k to arrange distribution series of the fractional-slot windings. The arrangement method is simple and easy to understand, convenient to memorize, grasp and use, thus, the arrangement method is completely suitable for the arrangement of frictional-slot double-layer windings, more importantly, particularly suitable for the arrangement of various frictional-slot single-layer windings.
