1. An electric rotating machine comprising:
a stator including a stator winding constituted of a plurality of U-shaped conductor segments each including a turn portion and two straight portions, the U-shaped conductor segments being connected in series by welding at welded portions formed in ends of the straight portions, and a stator core formed with slots, the straight portions of each U-shaped conductor segment being accommodated in corresponding two of the slots; and a rotor, wherein a welded side slot pitch is the interval along the circumferential direction between two straight portions of each conductor segment on a welded side, and the welded side slot pitch is narrower than an N-S magnetic pole pitch of the rotor, and the stator winding includes overlapped wire wrapping sections each constituted of the U-shaped conductor segments accommodated in the corresponding two of the slots, and crossover wires disposed on the side of the welded portions for connecting the overlapped wire wrapping sections, wherein the crossover wires include first crossover wires for connecting the ends of the U-shaped conductor segments disposed on an innermost side of the stator core, and second crossover wires for connecting the ends of the U-shaped conductor segments disposed on an outermost side of the stator core. |
