ABSTRACT:
A circuit for driving and braking a variable speed D.C. motor. A braking resistance has a terminal connected to the field winding of the motor. A diode is connected between this terminal and a quenching diode of the braking circuit to reduce the limiting effects of voltages produced across a reversing condenser in the braking circuit.
