ABSTRACT:
An automotive alternator comprises: a stator provided with a stator coil; a rotor supported for rotation in the stator to apply an alternative magnetic field to the stator; a regulator for regulating output; a rectifier for rectifying generated current; a plurality of housings holding the stator and the rotor; and a coolant path through which a coolant flows through at least one of the plurality of housings to transfer heat generated in the stator coil outside the automotive alternator. Fastening devices formed of a material having good heat conductance fasten the regulator and a heatsink for the regulator together to the housing at a position apart from the housing to transfer heat generated by the regulator to the housing. Thus, the automotive alternator can maintain a stable cooling ability in a hot atmosphere for a long time.
