Patent ID: 8836195

Claim:
A winding structure of a winding in a motor comprising a stator in which a plurality of slots are formed and a rotor, wherein an overall parallel winding formed of three phases and having a total number of parallels p is wound in the plurality of slots of the stator, when m is half of a number of slots of one phase of the plurality of slots of the stator and n is a divisor of m, the overall parallel winding of the total number of parallels p is equally divided n-fold into partial parallel windings Ni, where i is an integer from 1 to n, having a number of parallels p/n, each partial parallel winding Ni comprises m sub-coils, the m sub-coils including n types of min sub-coils of a number of turns tj where j is an integer from 1 to n, at least one of the sub-coils differing in number of turns from the other sub-coils, and for each pair of the slots in the stator, one sub-coil of each partial parallel winding Ni is wound around the pair of the slots, and n sub-coils wound around the pair of the slots include every one of the n types of the sub-coils of the number of turns tj.
