Abstract

The invention discloses a direct current energy consumption brake control method, and relates to the technical field of electrical equipment manufacture. When a motor prepares to operate, a circuit breaker is switched on, a start button is pressed, a first contactor control circuit is powered on, the motor starts, at the moment, a normally-closed contact of a first contactor in a brake circuit is switched off, a normally-open contact of the first contactor is switched on, and a capacitor is charged; when the motor prepares to stop, a stop button is pressed, the first contactor control circuit is powered off, the normally-closed contact of the first contactor in the brake circuit is switched on, the normally-open contact of the first contactor is switched off, the capacitor discharges for a relay, the relay attracts, a second contactor control circuit is powered on, and direct current energy consumption brake is performed; and after a certain period, the capacitor finishes discharging, the relay releases, the second contactor control circuit is powered off, and the brake is ended. According to the method, the problem that the cost of motors with frequent starting and brake and employing mechanical brake is high can be solved.

Description

technical field [0001] The invention relates to the technical field of electrical equipment manufacturing; in particular, a control method applied to motor braking. Background technique [0002] The motor is an indispensable part in industrial production. Many equipment can only be operated by the motor. In many occasions, the motor needs to be able to brake quickly. Now there are many methods of motor braking. For example, electromagnetic brakes are a common method of motor braking. , and for some motors that require frequent starting and braking, frequent braking will shorten the life of the mechanical braking equipment, thereby increasing the production cost of the enterprise. Contents of the invention [0003] The purpose of the present invention is to provide a DC energy consumption braking control method, which can solve the problem of high cost of mechanical braking for motors that frequently start and brake. [0004] In order to solve the above problems, the techn...
