INTERPHASE INSULATING SHEET FOR ROTATING ELECTRIC MACHINE, AND MOTOR-DRIVEN COMPRESSOR

摘要

An interphase insulating sheet for a rotating electric machine includes a pair of insulating portions and a plurality of bridge pieces. The insulating portions perform interphase insulation between coil ends of coils protruding from both ends of a stator core. Each insulating portion has bridge bases. The bridge pieces are each inserted in one of slots. Each bridge piece extends from a bridge base of one of the insulating portions to a bridge base of the other insulating portion. Each insulating portion has an annular shape having stacked parts that include a bridge base and overlap with each other by a predetermined margin. In the circumferential direction of each insulating portion, the dimension of the stacked parts is set to be less than or equal to the dimension of the bridge pieces.
