Abstract

PURPOSE: To halt a direct current motor more rapidly, by quickly decelerating the motor by changing over relay switches and by automatically bringing applied voltage to 0 when the number of revolution of the motor reaches 0 or a value nearly 0.
CONSTITUTION: A bridge is formed by resistances R13 and R14, a resistance RM of a motor 5 and a resistance R15, and the bridge is beforehand equilibrated. A relay is demagnetized by the OFF of a switch 2, and relay switches 3, 4 are changed over at the side b. Voltage V=V15-V14 between both bases of transistors 20 and 19 is V=R14.EM/(R13+R14) because of relationship of bridge equilibrium, and V is positive, the transistor 19 is at ON and 20 is at OFF when back electromotive force with high potential at the side A is produced. When the transistor 19 is at ON, a transistor 21 is also at ON, and plugging is applied. When the number of revolution of the motor reaches 0, the transistors 19 and also 21 are at OFF, and revolution of the motor 5 is halted.
