Rotating Electric Machine and Method for Manufacturing the Rotating Electric Machine

A stator for a rotating electric machine comprising:

• a stator core having a plurality of slots aligned along a circumferential direction;
• and
• a stator coil with an insulation coat inserted into the slots of the stator core;
• wherein the stator coil includes:
• main coils of a plurality of phases in which a plurality of segment coils each having a rectangular cross-section wire formed into a substantially U-shaped wire is connected to each other;
• first sub-coils each having a first lead wire led from the slots and attached with an AC terminal, and connected to one end of the respective main coils;
• and
• second sub-coils each having a second lead wire led from slots different from those of the first lead wire, and connected to the other end of the respective main coils;
• wherein the first and second lead wires are each formed of a wire with a bend structure having a plurality of straights and bends;
• and
• wherein the bends of the first and second lead wires are formed having different curvatures from each other above a coil end of the stator coil so that lead wires attached with the AC terminal are parallel.
