ABSTRACT:
An alternator disposed in the engine compartment of a vehicle is composed of a rotor having magnetic poles and a field coil, a cooling fan member, a stator disposed around the rotor and having a stator core and a multi-phase stator winding. The multi-phase stator winding has a plurality of conductor segments each having a U-turn portion to form a first coil-end group and a pair of joint portions to form a second coil-end group. The first coil-end group is disposed where temperature is higher than the other end, and the second coil-end group is disposed on the other end. The cooling fan member sends less cooling air to the second coil-end group than the first coil-end group.
