Claims

[Scope of utility model registration request]

(1) When winding a motor stator, in a device in which interphase insulation is applied between the coil end and different phase windings, the interphase insulating plate is formed into an arcuate ring shape, and projections protruding inward on the inner diameter side of both ends thereof. A plurality of interphase insulating plates are formed by bending both ends of each interphase insulating plate including the protrusions and stacking them together to form an approximately conical annular interphase insulating member. An interphase insulation structure for an electric motor, characterized in that the inner diameter side is inserted into the stator core side.

(2) The interphase insulating plate has a notch in the center thereof extending in the radial direction from the outer diameter side, and the notch has a width wider on the outer diameter side than the bottom part, and the bottom part is shaped like an arc. An interphase insulation structure for an electric motor according to claim 1 of the utility model registration claim.
