Abstract:
1. A stator for a dynamoelectric machine comprising: a hollow cylindrical stator core having a plurality of slots that are formed in a radially inner surface of the stator core and spaced at predetermined intervals in a circumferential direction of the stator core; and a stator coil made up of a plurality of wave-shaped electric wires mounted on the stator core, each of the electric wires having a plurality of in-slot portions, each of which is received in one of the slots of the stator core, and a plurality of connecting portions each of which is located outside of the slots of the stator core to connect one adjacent pair of the in-slot portions of the electric wire, each of the connecting portions including an apex part that is located axially furthest in the connecting portion from the stator core and includes an oblique section, the oblique section extending obliquely with respect to a radial direction of the stator core with an oblique angle between the oblique section and the radial direction, wherein the oblique sections of the apex parts of the connecting portions of the electric wires located on one axial side of the stator core are oblique in the same direction as those located on the other axial side of the stator core.
