Construction of a ceiling fan

The structure of a ceiling fan consists of the following main parts:

  • Electric motor: two main types are capacitor type and short circuit type, with the main parts of motor design including 2 types, stator and rotor. This is also the most important part among the details that make up a ceiling fan because it directly affects the quality of the fan such as (rotation speed, wind speed, equipment operation).
  • Propeller: this is the main part to create cool wind. Previously, the propellers were usually made of iron with three main ways arranged at a 120-degree angle to attach to the upper cutting board of the Roto. However, today, with modern technical improvements, the material and quantity of the fan blades have become more diverse for users to choose from (such as 3-blade ceiling fan, 4-blade ceiling fan or even 5-blade ceiling fan, …) .
  • Gear box of ceiling fan: this is the part used to adjust the fan speed according to the wishes and needs of the user.

Working principle of ceiling fan

Whether it is a ceiling fan with a beautiful design or a simple ceiling fan, depending on the technology and manufacturer, each type of ceiling fan will have different operating methods. However, in general, all ceiling fans in general must follow a basic operating principle as follows:

When connected to the power source, it will help start the fan, continue to rotate the internal motor, from which the electric motor will begin to operate and convert according to the established rules and directions. The rotating motor means that the rotor mounted on the Roto will also rotate. Rotating fan blades create fast or slow airflows, depending on the rotation speed of the internal motor, which is adjusted to the needs of the user through the ceiling fan gearbox.

Steps to connect ceiling fan switch

How to connect the ceiling fan switch includes the following 7 big steps:

Step 1: Install the top cover of the ceiling fan with the lower pillar to the main shaft.

During the installation process, some common errors and failures may occur. Here’s what causes those problems and how to fix them to make the installation process less awkward:

  • The ceiling fan may rotate in the wrong direction due to the wrong wiring between the two working coils and the starter coil when coming out to the terminal box. From there you need to swap the positions of these two wires at the fan to the original terminal box.
  • The fan is shaken in the user (spinning) fan: it may be caused by the warping of one of the three rotating main blades or the lack of spacers for the propeller. You need to disassemble the fan device to check it again and fully equip the spacers on the three blades with the fan body.

How to connect ceiling fan potentiometer

What is potentiometer?

Fan potentiometer (with the English name is Dimmer switch fan) is a very compact, modular electrical device that allows installers to disassemble with the effect of changing the rotational speed of the ceiling fan.

The ceiling fan potentiometer consists of an alloy main coil with high power resistance and is wound around by a conductive post attached to a C or hand crank. On the surface of the fan potentiometer, there is a design with a vortex knob or another type that is a lever type. This tool is connected to the sweep bar from which to create two resistors that are changed according to the position of the sweep bar (which can be understood as the increase or decrease in fan rotation speed).

How to solve the problem?

The operating principle of the ceiling fan potentiometer is almost the same as the gearbox of the ceiling fan. However, with the following outstanding advantages, ceiling fans using potentiometers are becoming more and more popular and used:

  • The design is more convenient, compact, and luxurious for the house than the gearbox.
  • Using for a long time continuously also do not worry about getting stuck or slipping.
  • Installation and replacement are very simple and fast.
  • Adjusting the rotation speed of the ceiling fan is “stepless” quite different from the gearbox that has to adjust the order and turns of rotation speed in turn.
