ABSTRACT:
An ac generator for a vehicle comprises a rotor field core fixed on a rotary shaft and magnetized by a field coil, a stator armature core surrounding the rotor field core, a stator armature coil wound on the stator armature core, an enclosure for liquid-tightly covering the stator armature coil, a generally cylindrical front bracket and a rear bracket. The front and the rear brackets are mounted directly to the cylinder block of the engine for defining a coolant passage between the front bracket, an outer wall of the rear bracket and an outer surface of the enclosure, the coolant passage having an inlet port connected to a upstream portion of an engine coolant passage and an outlet port connected to a downstream portion of the engine coolant passage, so that a portion of engine coolant flows through the coolant passage to cool at least the stator armature coil and the stator armature core.
