Abstract
A homopolar dynamoelectric machine is provided with current collecting structures which produce a peripheral, circumferential component of load current for self-excitation. The current collection structures include brush boxes which are skewed at a first angle with respect to the rotor axis and a generally cylindrical stator conductor having slits which are skewed at a second angle with respect to the rotor axis. Current flowing in the brushes and stator conductor is forced to have a circumferential component which compensates for rotor saturation due to load current and minimizes the voltage droop characteristic of drum-type homopolar generators.
