Abstract
A stator for a rotary electric machine, including a stator core having a plurality of slots, and a multi-phase stator coil wound around the stator core by double-layer winding. The multi-phase stator coil is formed by winding a plurality of double-wound coils around an entire circumference of the stator core for each phase, each of the double-wound coils being wound concentrically with different circumferential lengths. Each of the double-wound coils is formed of a coil portion having a larger circumferential length and a coil portion having a smaller circumferential length. In one of the double-wound coils, a total number of coils inserted into the plurality of slots for the coil portion having the larger circumferential length and a total number of coils inserted into the plurality of slots for the coil portion having the smaller circumferential length are equal to each other.
