ABSTRACT:
To form a compact combination structure which provides efficient cooling and ease of assembly, maintenance and repair, while reducing the number of elements necessary to be stocked for maintenance or repair purposes, the rectifier portion of the alternator-rectifier combination comprises two groups of rectifiers which are, respectively, set in openings of two disk-shaped support plates 15, 35, which have, each, ring-shaped portions 38 surrounding the shaft and radially projecting fins 39, 39'. One of the plates is formed with a hub to retain one of the bearings, the outer portion of the fins is apertured for attachment to the shell of the alternator, and additionally deformed to provide seating surfaces for accurate positioning, for example by externally applied punch marks, of the plate. An insulating spacer 43, 43' separates the two plates which are so positioned that the fins of one plate are opposite the gap between fins of the other, so that air drawn axially by a ventilating fan will cool both plates.
