Patent ID: 8159105

Claim:
A method of manufacturing a stator for an inner-rotor type rotary electric machine, characterized in that the method comprises steps of: preparing a cage stator coil that is a distributed-winding coil formed by circumferentially arranging a number of slot-accommodated conductor portions to be accommodated in respective slots of a stator at a predetermined pitch and at a position radially distanced from an axis of the stator by a predetermined length, and a cylindrical stator core configured by a plurality of segment cores; forming a concave-drum stator coil by reducing a diameter of the cage stator coil at an axial center portion thereof so as to be shorter than a diameter at each axial end portion of the cage stator coil; setting end segment cores at an axial center portion of the concave-drum stator coil, the end segment cores configuring cylindrical end cores that form respective axial end portions of the stator core, followed by displacing the end segment cores in an axial direction so as to be set at the axial end portions of the stator core; and setting center segment cores at the axial center portion of the concave-drum stator coil, the center segment cores configuring a cylindrical center core that forms the axial center portion of the stator core.
