ABSTRACT:
A brushless exciter for a dynamoelectric machine includes a rectifier assembly disposed in a cylindrical cavity on an axis of the shaft of the dynamoelectric machine. The rectifier assembly is made up of a stack of generally circular heat-sink discs with a cylindrical diode sandwiched on the axis between adjacent pairs of the heat-sink discs. A predetermined value of contact force is applied to the diodes through the stack of heat-sink discs using a plurality of tensioning bolts passing through the stack and tensioned using Belleville springs. All electrical connections to the diodes are made through the heat-sink discs using conductor bars which pass in aligned slots in the edges of the heat-sink discs, each making contact with only a desired single one of the heat-sink discs. A plurality of air flow openings in the heat-sink discs both permit the passage of air therethrough and also flow cooling air onto the body of the diodes. The flow of cooling air is enhanced by providing exit openings for the cooling air which are located at greater diameters than the diameter of the cylindrical cavity containing the rectifier assembly. This permits centrifugal force to add to the air flow.
