Abstract
A system and method for selective activation and deactivation of electrical brushes used in a dynamoelectric machine for current density optimization is disclosed. The approach includes using an arrangement of switches electrically connected to the electrical brushes to selectively activate and deactivate the brushes during the operation of the dynamoelectric machine. This entails opening and closing selective ones of the switches for a predetermined time period to adjust the average current density of the electrical current passing through the electrical brushes to be within a predetermined current density range while the dynamoelectric machine is operating.
