ABSTRACT:
A rectifying unit has two heat radiation fins to which positive-electrode side and negative-electrode side rectifying elements are fixed respectively. A terminal platform having a connecting terminal provides wiring for the positive-electrode side rectifying element and the negative-electrode side rectifying element. Two heat radiation fins are disposed in a radial direction with respect to a rotary shaft of the rotor. The negative-electrode side heat radiation fin is interposed between the frame and the positive-electrode side heat radiation fin, and is partly overlapped with the positive-electrode side heat radiation fin in the direction of the rotary shaft. An inner radius of the negative-electrode side heat radiation fin is smaller than an outer radius of the cooling air inlet window.
