Abstract
A plurality of coils Cto Cthat constitutes a whole winding L of each phase is divided into g coil groups Gto Gfor each phase. Each coil group is, for example, constituted by coils Cto Cwound around four polar teeth continuously disposed. The number of turns of respective end coils Cto Cof the coil group is less than the number of turns of central coils Cand C. Further, the whole winding L includes n partial windings Nto N, in which a coil Cj (j is an integer in the range from 1 to m) is constituted by n sub coils S(1,j) to S(n,j) that are formed by the n partial windings. It is feasible to set a non-integer value as an effective number of turns of a coil when the number of turns of each sub coil is appropriately selected.
