PURPOSE:To prevent the coil end section of a stator coil from being deteriorated because of discharge without missing miniaturizing components and lightening the weight normally, by providing insulation layers for corner sections on the surface confronting a stator frame, dash boards, and the coil end of a fan. CONSTITUTION:Insulation layers 6 are provided for corner sections on the surface confronting a stator frame 3, dash boards 4a, 4b, and the coil end 2a of a fan 5. In this manner, the coil end 2a section of a stator coil 2 can be prevented from being deteriorated due to discharge, miniaturizing components and lightening the weight normally. |
