Electronic centrifugal switch, this thing may sound a bit sophisticated, but in fact, it is a common electrical accessory in our daily life. Especially in some equipment that needs automatic control, such as electric fans, electronic centrifugal switches play a key role. So, when we are faced with an electronic centrifugal switch with four wires, how do we wire it? Don't worry, let me tell you more.
First of all, we must understand that the basic working principle of the electronic centrifugal switch is to touch the internal micro switch through the centrifugal force of rotation, so as to control the on/off of electrical appliances. This kind of switch is especially useful when the motor is started and stopped, which can effectively prevent the motor from starting suddenly in a stationary state, thus protecting the motor from damage.
So, what do we do with these four lines? In general, the four wires of an electronic centrifugal switch include two main power lines, an output wire, and a ground wire. Among them, the main power line is responsible for providing the working voltage for the switch, the output line is the signal line for controlling the electrical appliances, and the ground wire is designed to ensure the safety of the equipment.
First, we have to plug the main power cord into the power supply. It should be noted here that the positive and negative poles of the power supply cannot be reversed, otherwise the switch may not work properly or even be damaged. Then, we need to connect the output wire to the appliance that needs to be controlled. For example, if you want to use this switch to control an electric fan, you have to connect the output cable to the motor cable of the electric fan. Finally, the ground wire should be connected to the ground wire position of the appliance to ensure the safety of the equipment.
It may seem like a simple step, but it's easy to make mistakes in practice. Many people are careless and turn the wire in the opposite direction, resulting in the device not working properly. Therefore, you must be careful and careful when wiring to ensure that each wire is connected in the correct position.
In addition, while an electronic centrifugal switch can protect the motor from damage to a certain extent, it cannot be relied upon completely. In the daily use of the motor, we still have to pay attention to care and maintenance. For example, the motor should be inspected, cleaned and lubricated regularly to ensure that the motor will serve us for a long time.
Speaking of which, some people may ask: don't we all use that kind of brushless DC motor now? Do you still need an electronic centrifugal switch? In fact, although brushless DC motors improve the performance and life of the motor to a certain extent, they also need electronic centrifugal switches to protect. This is because no matter what kind of motor it is, it can be damaged by excessive current when starting and stopping. Therefore, the existence of electronic centrifugal switches is still very necessary.
In short, although the wiring of the four wires of the electronic centrifugal switch seems complicated, as long as we follow the correct methods and steps, it is actually not difficult. And, in order to ensure that our equipment can serve us for a long time, we also have to pay more attention and maintenance to the daily use of the motor. Only in this way can our devices really do what they should do.
