ABSTRACT:
An alternator for a vehicle which maintains or improves the cooling performance and which reduces the fan noise caused by the interference between the cooling winds and the stator windings. An armature coil provided on a stator of the alternator includes an X-phase coil group, a Y-phase coil group, and a Z-phase coil group. Coil end groups are sets of coil ends forming bridge wires between slots. The coil end groups have stationary blade shapes which form passages for the cooling winds directed from a cooling fan on a rotor toward outlets in a frame. The sound of the interference between the cooling winds and the coil end groups is reduced while the cooling performance is enhanced.
