Abstract: A rotary electric machine includes a rotor and a stator. A stator core has n in-phase slots provided in the circumferential direction and correspond to magnetic poles, and into each of which phase windings of the same phase are installed. Each of the phase windings is divided into 2n portions in an extending direction so that each of the phase windings is configured by a first partial winding, a second partial winding, . . . , and a 2n-th partial winding arranged from one end positioned in the extending direction in sequence. The first partial winding and the 2n-th partial winding are inserted into different in-phase slots of the stator core. Counted from one end positioned in the extending direction, the 2m-th (1≦m≦n) partial winding at an even-numbered position and the (2m−1)-th partial winding are inserted into different in-phase slots of the stator core.
