发明名称 METHOD FOR MANUFACTURING STATOR OF ROTARY ELECTRIC MACHINE
摘要 PROBLEM TO BE SOLVED: To provide a method for manufacturing a stator of a rotary electric machine capable of preventing occurrence of cyclic current between parallel-connected coils and also improving productivity of the coils.SOLUTION: In a stator 13 for a rotary electric machine M, two coils 25 for each of three phases are respectively connected in parallel. A method of winding the coil whose coil pitch is a value (6) obtained by dividing the number (48) of slots 24 by the 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 a stator core 22.
