電制御装置。In a device for driving a separately excited DC motor having a shunt field winding with a mixed bridge type thyristor rectifier equipped with a commutating diode on the DC side, a dynamic braking resistor and the commutating diode are connected in series, and connected in parallel with the main circuit contactor,
When applying dynamic braking, the excitation of the shunt field winding is reversed to reverse the back electromotive voltage of the separately excited DC motor, and a means for flowing a braking current to the dynamic braking resistor through the commutating diode. A power generation control device for a DC motor, characterized in that it is provided with:
