ABSTRACT:
Regenerative brake control system for DC motor, in which a resistor is inserted in the motor circuit to effect regenerative brake control from a high speed by use of a chopper. In the voltage control region where the motor voltage less the voltage drop across the inserted resistor is controlled below an equivalent source voltage, the inserted resistor is not short-circuited, thus improving the efficiency of the regenerative brake.
