Abstract
The invention, which relates to the technical field of electrical equipment manufacturing, discloses a reversible brake motor control method. When a motor rotates forwardly and the rotating speed of the motor is higher than 120 rpm, a normally-open contact of a speed relay in a reversed braking control circuit is turned off and preparation for reversed braking is made; when working of the motor needs to be stopped, a stop button is pressed, a relay actuation circuit is electrified, the reversed braking control circuit is electrified, and the motor enters a reversed braking working state. When the motor rotates reversely and the rotating speed of the motor is higher than 120 rpm, a normally-open contact of a speed relay in a forward braking control circuit is turned off and preparation for forward braking is made; and when working of the motor needs to be stopped, a stop button is pressed, a relay actuation circuit is electrified, the forward braking control circuit is electrified, and the motor enters a forward braking working state. Therefore, a problem that the cost is high because a small-capacity motor employs other equipment for braking is solved.
