Abstract
The purpose of the present invention is to provide an inter-phase insulation sheet for a rotating electric machine, wherein it is possible to produce the effects of exerting excellent insertion workability between coil ends of different phases, of preventing the positional misalignment of the inter-phase insulation sheet during production work when forming the coils or when lacing, of preventing the inter-phase insulation sheet from tearing when lacing, and of being able to reliably ensure that the coil ends are insulated from one another even when the shape of the coil ends are not the same. In order to achieve the aforementioned purpose, an inter-phase insulation sheet () has a fixed section () and a movable section (). The movable section () has a base section (A) on one side and a flanged section (B) on the other side. The fixed section and the base section are placed so to completely overlap with one another and are inserted between coil ends () of different phases. Meanwhile, the flanged section passes the inner side () of one of the coil ends of different phases and is drawn from the insulation sheet insertion side of the coil end out to the side opposite that of the insulation sheet insertion side. Moreover, in order to facilitate the flanged section to be drawn out, a slit is formed between the fixed section and the base section and between the center and the side of the base section.
