Patent ID: 8186039

Claim:
A method of manufacturing a coil assembly of a rotary electric machine by weaving coil wire segments, each including in-slot portions disposed inside slots of a stator core and turn portions disposed outside the slots and connecting the in-slot portions disposed in the slots that are different in a circumferential direction; comprising: a placing step of placing a first coil wire segment and a second coil wire segment which are bent at a connection between the in-slot portion and the turn portion so as to be opposed to each other in order that a first turn portion of the first coil wire segment and a first turn portion of the second coil wire segment intersect each other; a first engaging step of causing the first turn portion of one of the first and second coil wire segments to engage a second turn portion of the other one of the first and second coil wire segments by performing an engaging movement including a forward transferring movement to transfer the second coil wire segment forward to the first coil wire segment, a rotating movement to rotate the second coil wire segment about an axis direction, and a translating movement to translate the second coil wire segment; and a second engaging step of causing the first turn portion of one of the first and second coil wire segments to engage with a third turn portion of the other one of the first and second coil wire segments by performing the engaging movement.
