Electric motor

This is the part that creates rotation for the fan, usually there are 2 main types: capacitor type and short circuit type. To protect the electric motor, the manufacturer places it inside the fan bulb.


Is a part used to create wind, usually made from materials such as plastic, alloy, wood, fiberglass… and has many different colors. To meet the needs of a large number of customers, the manufacturer also creates a variety of ceiling fan blades that can be 3, 4, 5 or even 8 blades, 10 blades. The ceiling fan is attached to the fan bulb with screws and brackets.

Speed ​​regulator (gearbox)

A part used to adjust the wind speed of the ceiling fan. Ceiling fans can have from 3 to 9 wind speed levels.

Electrical box

In the ceiling fan structure, this is the part to connect the ceiling fan’s electrical wire to the indoor power line, which is mounted on the ceiling.

Hanging tube 

The part used to hang the fan on the ceiling.

Upper funnel

In the structure of the ceiling fan, this is the part used to cover the hanger part or the screw and electrical box on the ceiling.

Ceiling fan hook

An indispensable part when installing a ceiling fan. This part is up to you whether you purchased it directly from a fan distributor. If you don’t have one, you can still buy more. However, be careful when choosing a hook.

Some creating ceiling fans

  • Ceiling fans with lights

The structure of ceiling fans with lights is basically the same as that of traditional fans. However, this product has an additional lighting function with a variety of lights mounted below the propeller system, satisfying the needs of cooling cum lighting and aesthetic decoration of the space.

  • Remote control

Remote helps users to easily turn on and off the fan or adjust the wind mode, wind speed or timer to turn off the fan from any position without having to move to the light switch.

  • Gearbox

As one of the important parts of a ceiling fan and is often included with the ceiling fan, you do not need to pay extra. The basic ceiling fan gearbox structure consists of the outer box, the inside includes the speed regulator, the lower motor system, the assembly and the cylinder.

Ceiling fan products are now quite diverse, but basically the ceiling fan structure is the same as the above information. Ceiling fans can now be divided into 2 main types by design, including:

Two types of ceiling fans without existing wiring

Ceiling fan with blades

This is a cooling product designed from the outside to see the fan blades with different numbers and sizes. In this category you also have easy access to specific products:

– Traditional ceiling fan: A fan with wings that always spread out with a propeller span of 1.2 – 1.5 meters wide.

– Self-retracting ceiling fans: These are fans that when in operation they spread their wings, when they stop working, they retract their wings, saving space.

– Box ceiling fan: A type where the motor and propeller are designed to fit in a box frame, the blades are always spread, the blades are much shorter than traditional ceiling fans.

Bladeless ceiling fan

This cooling device is a breakthrough in the ceiling fan segment with the advantage of being compact, does not take up installation space, and is safe for users. This bladeless ceiling fan structure has a clever design of air holes, gently sucking in air from the bottom to the top, and blowing around in the cells next to the fan, creating a flexible 360-degree movement.

Thus, a ceiling fan without an electrical system is no different from a normal ceiling fan, they only differ in the way the power is applied.

What is the cable box of a ceiling fan?

The cable box of the ceiling fan is an important device of the ceiling fan and it has the effect of adjusting the wind speeds at certain wind levels. The cable box is now a device that comes with the fan, so customers will not need to pay extra when buying a fan.

Ceiling fan cable box is also known as a rheostat box and is made up of coils with different numbers of turns. The structure of the ceiling fan cable box consists of an outer box and an inner part that includes a regulator of rotational speeds, a motor system at the bottom, assembly and cylinders.

How to install a ceiling fan without existing wiring

Due to the technique of each type of propeller, the cable set without wires depends on the number of blades.
