Abstract
An object of the present invention is to suppress reduction of insulation reliability between stator coils. A method of manufacturing a rotary electric machine according to the present invention is a method of manufacturing a stator including an insulating member intervening between a plurality of coil end portions each protruding from a stator core, the method including: a first step of disposing an interposed member to cover part of the insulating member between the plurality of coil end portions; and a second step of welding part of each of the plurality of coil end portions.
Claims6
A method of manufacturing a stator including an insulating member intervening between a plurality of coil end portions each protruding from a stator core,
- the method comprising:
- disposing an interposed member to cover a part of the insulating member between the plurality of coil end portions, such that the interposed member is separated from each of the plurality of coil end portions and
- welding part of each of the plurality of coil end portions, thus forming a burnt portion of the insulating member and a burnt portion of the interposed member that covers the part of the insulating member;
- wherein the burnt portion of the interposed member suppresses burning of the covered part of the insulating member.
