INTER-PHASE AND INTRA-PHASE INSULATING PAPER OF MULTIPHASE DISTRIBUTED WINDING ROTATING ELECTRIC MACHINE, THREE-PHASE DISTRIBUTED WINDING ROTATING ELECTRIC MACHINE INCLUDING INTER-PHASE AND INTRA-PHASE INSULATING PAPER, AND MANUFACTURING METHOD OF THREE-PHASE DISTRIBUTED WINDING ROTATING ELECTRIC MACHINE HAVING INTER-PHASE AND INTRA-PHASE INSULATING PAPER

摘要

PROBLEM TO BE SOLVED: To insulate coils of different phases and to insulate coils of the same phases by using a small number of sheets of paper, in a multiphase distributed winding rotating electric machine.;SOLUTION: The inter-phase and intra-phase insulating paper 10a is formed by assembling a plurality of bent paper pieces having inter-phase insertion parts 14 and intra-phase insertion parts 16. The inter-phase and intra-phase insulating paper 10a has a ring shape by being annularly shaped as a whole by alternately connecting the intra-phase insertion part 16 of each bent paper piece 12 and the intra-phase insertion part 16 of each bent paper piece 12, and an intra-phase insulating part 18a formed of the intra-phase insertion parts 16 is oriented to the external peripheral direction of the ring shape. Eight pieces of the bent paper pieces 12 are annularly arranged, the intra-phase insertion parts 16 are connected to one another, and one inter-phase and intra-phase insulating paper 10a is formed.;COPYRIGHT: (C)2009,JPO&INPIT
