INTERPHASE INSULATING SHEET OF ROTATING ELECTRIC MACHINE, METHOD FOR MANUFACTURING INTERPHASE INSULATING SHEET, AND ELECTRIC COMPRESSOR

摘要

An interphase insulating sheet of rotating electric machine is disclosed The interphase insulating sheet includes a first insulating portion, a second insulating portion, and at least one bridge piece. The first insulating portion includes at least one first coupling aid integrally provided with the first insulating portion to extend from an opposing end of the first insulating portion facing the second insulating portion. The second insulating portion includes at least one second coupling aid integrally provided with the second insulating portion to extend from an opposing end of the second insulating portion facing the first insulating portion. A first end portion of the bridge piece is heated welded to the first coupling aid. A second end portion of the bridge piece is heated welded to the second coupling aid. The first coupling aid has a first positioning hole. The second coupling aid has a second positioning hole. The first end portion of the bride piece includes a third positioning hole, which overlaps the first positioning hole. The second end portion of the bride piece includes a fourth positioning hole, which overlaps the second positioning hole.
