Abstract
PURPOSE:To enable rapid braking by a method wherein a controlling power source for a DC motor is separated when abnormality is generated at the power source while a speed voltage component among the terminal voltage of the motor is detected, and the component is inverted and added to the terminal voltage. CONSTITUTION:A DC motor 2 is driven through a power amplifier 1. When abnormality is generated at a controlling power source for the motor 2, a switch 101 is turned OFF, and switches 11, 102 are turned ON. Thus, both end voltage of a motor current detecting resistor 12 is forwarded to a voltage-drop detecting circuit 13 of a motor series resistor RM, the output and the voltage of a motor terminal are given to a speed voltage component detecting circuit 14, and a speed voltage component of the difference is obtained by inverted polarity. The component is returned to the input side of the amplifier 1 through a resistor Rf, and terminal voltage having opposite polarity is applied to the motor 2. Thus, rapid braking which cannot be acquired by dynamic braking by direct short circuit can easily be conducted.
