Abstract:
1. A rotary electric apparatus, comprising: a rotary unit provided with a rotor and an armature disposed as a stator around the rotor, the armature comprising an armature winding generating an AC (alternating current) current when the rotor is driven to rotate; a semiconductor-type power converter electrically connected to the armature winding of the armature of the rotary unit and equipped in the rotary unit; and a fan motor electrically connected, in parallel with the power converter, to the armature winding of the armature of the rotary unit so as to receive the AC (alternating current) current and driven to cool down the power converter in response to excitation by AC (alternating current) current from the armature winding of the armature.
