Usually, there are three ways of emergency stop braking of the reducer: mechanical braking, generator braking and reverse braking. The fastest braking is reverse braking. Let's take a look at the requirements of this braking method.
1. To better solve the problem, it is necessary to know the characteristics of the reducer load and the specific requirements for use.
2. The motor drive circuit controlled by the single-chip microcomputer needs to have the power supply reverse connection function, such as a bridge circuit composed of 4 transistors, or a forward and reverse circuit composed of relays.
3. When braking is required, the control circuit switches the short circuit to the state of motor reversal. When the motor speed drops to 0, the power supply is stopped when the motor is to be reversed. .The motor stops.It should be noted that due to the load change, the time required for the motor speed to drop to 0 from the start is not constant.
In addition, the reducer needs to be equipped with a speed sensor, otherwise it needs to use more complex control technology, such as adaptive control, at this time, you need to master it well for professional control.
