Stator winding for rotary electric machine, stator for rotary electric machine, method of manufacturing stator for rotary electric machine, and jig used in manufacturing stator for rotary electric machine
A stator winding of a rotary electric machine includes windings for each pole of each phase being configured by a single layer lap wound coil. The single layer lap-wound coil includes combination coils each configured by two or more divided unit coils of the same phase being disposed one over the other in a radial direction inside slots of a stator core. The combination coils each comprise a first-row unit coil and a second-row unit coil disposed in a radially inner side of the stator core with respect to the first-row unit coil. A turns count of the first-row unit coil equals a turns count of the second-row unit coil. A count of lead wires of the first-row unit coil differs from a count of lead wires of the second-row unit coil.
