Abstract

A rotary electric machine (10;110;210;310;410;510;610) includes a stator core (22) having a plurality of slots (22s), and a three-phase coil (24;124;224;324;424;524;624) including coil segments (80) received in first through sixth layers in the slots (22s). Some of the coil segments received in the third and fourth layers in the same slot (22s) are different from each other in phase. A phase coil (40,50,60;140,150,160; 240,250,260;340,350,360; 440,450,460;540,550,560;640,650,660) of each phase in the three-phase coil (24;124;224;324;424;524;624) includes an inward winding portion (42a,44a,52a,54a,62a,64a; 142a, 144a, 152a, 154a, 162a, 164a;242a,244a,252a,254a,262a,2 64a;342a,344a,352a,354a,362a,364a;442a,444a,452a,454a,462a,464a;542a,544a,552a,5 54a,562a,564a;640a,640c,650a,650c,660a,660c) and an outward winding portion (42b,44b,52b,54b,62b,64b; 142b, 144b, 152b, 154b, 162b, 164b;242b,244b,252b,254b, 262b,264b;342b,344b,352b,354b,362b,364b;442b,444b,452b,454b,462b,464b;542b,544 b,552b,554b,562b,564b;640b,640d,650b,650d,660b,660d). Each of the inward winding portion and the outward winding portion includes an outer-layer connection portion (Ro). Regarding a connection order of the coil segments (80) as seen from side of an input terminal (72, 74, 76) of the phase coil, connection of the coil segments (80) received in the third layer and connection of the coil segments (80) received in the fourth layer are made after the outer-layer connection portion (Ro) in the inward winding portion.
