ABSTRACT:
The coil-end portions of an armature winding are disposed around cooling fans and closely, and outer coil ends of the coil-end portions are disposed to be close to alternator frames via insulating layers. The coil ends are spaced apart from one another except the base portions, and the resistance of cooling air draft inside the coil-end portions is lower than that around the coil-end portions so that the cooling air mainly passes through the inside of the coil-end portions.
