Abstract
A compact rotor for a dynamoelectric machine in the form of a brushless alternator is provided through the use of a compact rotating rectifier of unitary construction and a suppression resistor which are mounted within the rotor. The rectifier is of an elemental construction in which all elements of the rectifier perform dual functions as essential structure and as elements of an electrical circuit. The rotor, rectifier, and resistor are highly integrated and configured in a complementary manner such that virtually all non-essential structure related to the rectifier and resistor are eliminated, and such that electrical connections between the components of the rotor are significantly simplified. The rotor also includes features for directing a flow of coolant about the rectifier and the resistor.
