    • An electric generator for a vehicle has a rotary generator shaft, a generator rotor mounted on the shaft and having a field winding, a bracket surrounding the generator rotor and having the generator shaft rotatably journalled therein, an inductor fixed to the bracket means and having an energizing coil with a plurality of poles, and an induced member rotatably mounted on the rotary generator shaft and opposed to the inductor with a minute gap therebetween, so as to be coupled to the inductor by an electromagnetic force when the energizing coil receives current from the generator. The generator stator is disposed around the generator rotor and has an armature winding with a number of poles exceeding twice the number of poles of the inductor and for generating an AC output usable for supplying power to a load outside the generator. The energizing coil is connected to the armature winding for receiving a part of the AC output for energizing the energizing coil. A cooling fan is integrally connected with the induced member and directs a cooling air flow over the generator.
