Abstract

PURPOSE:To stop a DC motor in an extremely short period of time without reversing said motor, by a method wherein the DC motor is fed with a reverse exciting current from a power source in the flowing direction of a dynamic braking current, and the reverse excitation is stopped immediately before the stoppage of the motor, with only the dynamic braking current allowed to flow. CONSTITUTION:To stop a DC motor M under a forward rotating state where switches SW1, SW4 are on while switches SW2, SW3 are OFF, first, the switches SW1, SW4 are also turned OFF to cut off the motor M from a power source, and the switches SW2, SW3 are turned ON thereafter. Thereby, a reverse current IVC flows through the motor M from the power source as well as a dynamic braking current IB of the motor M itself flows through a closed loop consisting of the switch SW2 a diode D3 the motor M, so that the motor M is rapidly decelerated. Before the motor M starts reversing, the switch SW3 is turned OFF to cut it off from the power source, with only the dynamic braking current allowed to flow. Acordingly, it is possible to stop the motor M without reversing the same.
