Patent ID: 8466598

Claim:
An electric rotating machine comprising: a stator core having a plurality of slots; and a multi-phase stator coil including a plurality of phase windings wound on the stator core in a distributed winding manner, wherein each phase winding is formed by conductively interconnected ends of pairs of insulation-coated lengths of conductive wires in an electric wire bundle, each of the electric wire bundles has a plurality of in-slot portions and a plurality of turn portions between ends of the conductive wires included therein, each of the in-slot portions being received in a corresponding one of the slots of the stator core, each of the turn portions being located outside the slots, and each of the electric wire bundles further includes a plurality of insulating layers that are formed at respective different predetermined positions at which the turn portions of the electric wire bundle overlap those of other electric wire bundles, so as to surround the electric wires of the electric wire bundle thus providing additional electric insulation between the different wire bundles.
