A generator has a bore connector having a threaded radial opening for receiving a sectional terminal stud. The terminal stud includes an adapter section having threads on a radial inner end thereof for threaded engagement with the bore copper and a recess at its opposite end. An outer section of the terminal stud is received in the recess, making electrical connection therewith through an electrical connector. The outer section is maintained in the radial bore of the rotor by a threaded nut. The rotational orientation of the adapter section is fixed by its threaded engagement with the bore copper, while the outer section can be inserted without regard to rotational orientation, thereby facilitating refurbishment of the generator without remachining the bore copper.

A rotating electrical machine with a reverse flow ventilation system is constructed with one or more discharge ducts at the center of the stator core to reduce the air gap pressure and promote more uniform cooling. In a second embodiment, discharge ducts are provided axially displaced from the center line of the core. In another embodiment, end region cooling of the conductor bars is enhanced by a series-parallel flow path constructed with the use of baffles and an apertured plate. In a final embodiment, both stator core center discharge ducts and series-parallel flow end region cooling are incorporated in the same machine.

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.
