Abstract

PURPOSE:To improve insulating function without using an inter-phase insulator by using an electrical wire with higher dielectric pressure-tight insulating coating than another coil when different phasial coils are overlapped at an coil end. CONSTITUTION:In the rotary electric machinery wound with a turbulently winding coil and when different phasial coils are overlapped at the coil ends, for one coil 8 thereof an electric wire with an insulating layer 5 strengthened by 1.5-2 times of the thickness of the existing ones is used. Further for another coil an electric wire same as the existing one is used. Thereby an insulating function can be improved with no inserted interphase sheet-like insulator.
