INSULATOR OF STATOR, STATOR FOR ROTATING ELECTRIC MACHINE USING THE SAME, AND METHOD FOR MANUFACTURING STATOR FOR ROTATING ELECTRIC MACHINE

摘要

An insulator 7 for insulating a coil 6 that is wound around a tooth 9 of a stator core 5 includes: an axial wall 20a that opposes an axial end surface of the tooth 9 in a state of being assembled to the tooth 9; and a circumferential wall 22a that is integrally provided with the axial wall 20a and opposes a circumferential-side surface of the tooth 9. The circumferential wall 22a that is located between the tooth 9 and the coil 6 is constructed of an insulating sheet 24 that is thinner than the axial wall 20a and has foamability.
