Title:
SWITCHING CIRCUIT FOR DC ROTARY ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JPS5662048
Kind Code:
A
Abstract:
A switching circuit electrically connected to a brush and collector bar of a DC dynamoelectric machine utilizing a high current rectifier and a source of electromotive source which produces a current in the circuit which is generally equal to the current flowing between the brush and the collector bar and which can be forced to zero as the brush separates from the collector bar to reduce degradation of the trailing edges of the brushes and collector bars and improve the machine efficiency.
