Abstract
An object of the present invention is to provide an electrical rotating machine capable of securing safety against collision. Included are a rotor having a field winding and cooling fans, and a stator having a stator winding, arranged so as to surround the rotor. A bracketis fixed to a load side end of the stator, and a heat sink is disposed inside the bracket. On the anti-load side of the heat sink, a field circuit unit and power circuit units for controlling the field winding and the stator winding, respectively, are mounted, whereas on the load side thereof, cooling fins are disposed. The anti-load side and lateral side of the field circuit unit and the power circuit units are surrounded by the bracket. Accordingly, a whole of the field circuit unit and the power circuit units is surrounded by the bracket and the heat sink.
