Reducer is a commonly used machine equipment in our industrial production. Although it can bring great convenience to our production operations, sometimes it will inevitably malfunction during operation. In this case, we need to perform emergency stop braking inspection to investigate the cause of the malfunction. There are usually three types of emergency stop braking for gearboxes, such as power generation braking, mechanical braking, and reverse braking. Among them, reverse braking is the fastest braking method. Next, let me take you through the requirements of this braking method.
1. When the reducer needs to brake, its control circuit will short-circuit and switch to the motor reverse state. When the motor speed drops to 0, the power supply will stop during reverse, and the motor will stop running. It should be noted that due to changes in machine load, the time required for the motor speed to decrease to 0 from the beginning of reverse connection also needs to be changed.
2. If you want to solve the problem well, you need to know the characteristics of the gearbox load and the specific requirements for use.
3. The drive circuit of the reducer motor controlled by a microcontroller needs to have the function of reverse power supply, such as choosing a bridge circuit composed of 4 transistors or a forward and reverse circuit composed of relays.
On the other hand, the gearbox needs to be equipped with a speed sensor, otherwise the equipment will require more complex control technologies such as adaptive control. In this case, it is necessary for everyone to master this technology well for professional operation.
The above content is all the requirements for reverse borrowing braking of reducers. I hope that my article can effectively help everyone to live in harmony with machinery and equipment in the future.
