STATOR FOR ROTATING ELECTRICAL MACHINE AND ROTATING ELECTRICAL MACHINE

摘要

The stator of an electrical rotating machine is provided with a stator core having a plurality of slots circumferentially disposed and a stator coil which is formed with a conductor having an insulating coating and a rectangular cross-section and is inserted into the slots. The stator coil is provided with first, second and third phase windings constituted by connecting a plurality of segment coils formed substantially in a U-shape, a first neutral wire which is formed with a continuous single conductor extending across a first slot and a second slot and connects the first phase winding with the second phase winding, and a second neutral wire which is pulled out from a third slot and connects the third phase winding with the first neutral wire.
