STATOR FOR ROTARY ELECTRIC MACHINE

摘要

Winding bodies include: a first terminal wire that extends outward at a first axial end of a stator core from a radially innermost position inside slots; and a second terminal wire that extends outward at the first axial end of the stator core from a radially outermost position inside the slots, the first terminal wires are each led radially outward over coil ends of the stator winding, the second terminal wires are each led radially outward at positions that are nearer to the stator core than end portions of the first terminal wires that are led radially outward over the coil ends of the stator winding, and end portions of intraphase connecting second terminal wires are stacked in an axial direction with, placed in contact with, and connected to end portions of intraphase connecting first terminal wires that are subject to connection therewith.

1. A stator for a rotary electric machine, said stator comprising:
an annular stator core in which slots are arranged circumferentially; and a stator winding that is mounted to said stator core,wherein:
said stator winding is configured by mounting distributed winding bodies to said stator core circumferentially at a pitch of one slot so as to be equal in number to a total number of said slots, said distributed winding bodies each being constituted by a jointless continuous conductor wire that is coated with insulation; said winding bodies comprise: a first terminal wire of said conductor wire that extends outward at a first axial end of said stator core from a radially innermost position inside said slots; and a second terminal wire of said conductor wire that extends outward at said first axial end of said stator core from a radially outermost position inside said slots; said first terminal wires are each led radially outward over coil ends of said stator winding; said second terminal wires are each led radially outward at positions that are nearer to said stator core than end portions of said first terminal wires that are led radially outward over said coil ends of said stator winding; and end portions of intraphase connecting second terminal wires that constitute intraphase connecting portions among said second terminal wires are stacked in an axial direction with, placed in contact with, and connected to end portions of intraphase connecting first terminal wires that constitute intraphase connecting portions that are subject to connection therewith among said first terminal wires.
