- the first insulating member 03 inserted into the first slot 02a defined between one split core is not suitable. Since the thickness is small, the split core 02 can be easily inserted into the coil conductor 05. Further, since the thickness of the first insulating member 03 can be approximately half that of the second insulating member 04, the workability of assembling the split core 02 to the coil conductor 05 can be improved.
- the present invention can be used in the field of rotating electrical machines, in particular, in the field of rotating electrical machines mounted on vehicles, and thus can be used in fields such as the automobile industry.
