Installation, principle and wiring of electric fan governor

Although the appearance of electric fan products looks simple, it seems that it is not difficult to know the principle of electric fan by analyzing its functional design and volume parameters. But in fact, many of its components play an important role that cannot be ignored. For example, the electric fan governor is one of the most important products. So the knowledge I want to introduce to you today is about the principle of electric fan governor and the matters needing special attention during installation and operation.

First, the principle of electric fan governor

The so-called resistance theory has no common sense. Resistance can be regarded as a load, and how much electricity is used when the resistance is large (the load is large) is no different from that of a light bulb electric furnace. Therefore, the design of electric fan considers speed regulation and does not consume too much power. At present, there are three kinds of speed governors, the older one is called reactor, which is actually a tapped autotransformer (usually an autotransformer without tap), which can change different voltages to make the fan have different speeds, and the other is an electronic speed governor. Using silicon controlled rectifier and potentiometer to change voltage belongs to stepless speed regulation, and another is frequency converter, which changes the frequency of alternating current instead of adjusting voltage, and also achieves the purpose of speed regulation. Because electric fans basically use AC asynchronous motors, the speed can be adjusted by changing the frequency.

There are two kinds of governors: induction governors and electronic governors. Inductive governor is an adjustable inductor connected in series in the circuit of fan motor, which changes the voltage drop on the fan and achieves the purpose of step-by-step speed regulation. The electronic governor changes the voltage of the fan motor by adjusting the conduction angle of the thyristor through a potentiometer, so as to achieve the purpose of stepless speed regulation. No matter what kind of governor it is, just connect the governor in series in the fan circuit.

All the household ceiling fans you mentioned have a capacitor of 400V 1-2μf, which is the starting capacitor, and plays the role of starting the motor. Then don't add the radiator of this distribution cabinet, because this motor doesn't need a starting capacitor.

Second, how to wire the electric fan governor

The neutral wire is directly connected to the electric fan, the live wire is introduced into the governor you are holding and connected to either end, and the other end leads to another wire connected to the electric fan (one ***3 wires, and the grounding is usually yellow and green, so you can't tell whether the grounding wire is connected to the iron case of the electric fan). Ok, remember to cut off the power.

Three, ceiling fan governor installation

Now the newly bought ceiling fan, the original governor is generally a capacitor governor, and there is a wiring screw on the left and right to connect the ceiling fan on one side and the ceiling fan on the other side. Commercially available governor wiring: there are two wiring holes on the back. L lines marked with L and A go into line A and out (ceiling fan), and A 1 marked with A/KLOC-0 and A2 go into line A2 and out (ceiling fan). Installation should be carried out in strict accordance with the instructions. There are several wires in it, and it is easier to succeed if these wires are connected correctly. Of course, it will be better to watch more videos and pictures and understand how it works.

The above has introduced a lot of knowledge to you, including not only the information that consumers are interested in, but also the knowledge that is of great reference value from the user's point of view. For example, the principle and installation instructions of the electric fan governor, and further information on the wiring steps of the electric fan governor. Friends who are interested in learning may wish to study and analyze according to the actual situation, and buy similar products or consider electric fan governors.
