PROBLEM TO BE SOLVED: To provide a stator 1 for a rotary electric machine which can prevent occurrence of cyclic current between parallel-connected coils and also improve productivity of the coils.SOLUTION: In a stator 13 for a rotary electric machine M, two parallel-connected coils 25 are disposed for each of three phases. A method of winding the coil, whose coil pitch is a value (6) obtained by dividing a number (48) of slots 24 by a number (8) of poles of the coils 25, is employed as a full-pitch winding. A method of winding the coil at a coil pitch larger than the coil pitch of the full-pitch winding is employed as a long-pitch winding. A method of winding the coil at a coil pitch smaller than the coil pitch of the full-pitch winding is employed as a short-pitch winding. A first U-phase coil 25U1 and a second U-phase coil 25U2 are wave-wound by alternately repeating the long-pitch winding and the short-pitch winding along a circumferential direction of the stator core 22. |
