Abstract
Official abstract text for this publication.
A rotating electric machine includes: a stator core having a plurality of slots aligned along a circumferential direction; a stator having a stator coil with an enamel coating inserted into the slots of the stator core; and a rotor rotatably arranged over the stator core through a given gap. 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 in advance is connected to each other; a first sub-coil having a lead wire led from the slots and attached with an AC terminal, and connected to one end of the respective main coils; and a second sub-coil having a neutral wire led from the slots, and connected to the other end of the respective main coils. The lead wire and the neutral wire are each formed of a wire with a bend structure having a plurality of straights and bends.
