Complete Guide for Ceiling Fan Parts: Names, Functions & Diagram

Nowadays, a ceiling fan is one of the fundamental pieces of equipment in every human being’s house because it creates a comfortable atmosphere within our homes. A ceiling fan does not change the room temperature. It distributes the air in the room. So, a cool breeze revolves around the room. In the summer season, a ceiling fan pushes the air downward to get a cool breeze, whereas, in the winter season, it drags the air in an upward direction to get warm air, which gives more comfort. To make a person comfortable, various ceiling fan parts are assembled to work smoothly. We all have to know the parts of a ceiling fan so we can do their maintenance and change any damaged parts whenever required.

As ceiling fans are widely used in both seasons, there is a chance of malfunction. So, to avoid such circumstances, we need to know the parts of a ceiling fan and their names and functions.

Parts of Ceiling Fan and their Function

Electric Motor

The electric motor is called the heart of the ceiling fan. Its function is to convert electrical energy into mechanical energy.

When an electric current passes through the coil of the electric motor, the magnetic field generated within the coil leads to the coil rotation. This rotation energy is transferred to the fan blades.

So, thereby, fan blades are moving. Generally, it uses a single-phase capacitor-run induction motor whose rated voltage is 230 V ± 10 % with a frequency of 50 Hz.

Motor Housing

Motor housing is the cover of the motor, which is made of iron. Its function is to protect the motor from dust and debris. Another function of the motor housing is to make the fan neat and decorative without showing the inner operation motor.

Mounting Mechanism

The mounting mechanism is nothing but a fixture used to attach the fan to the ceiling. Several mechanisms are available, but the ball and socket system and J hook with shackle clamp are the common mounting mechanisms.

The ball and socket system works with a mounting bracket of the fan, which fits the bottom of the down rod. J hook and shackle clamp fit directly to the ceiling of the home with a rubber grommet, which absorbs vibration caused by rotation.

This mounting mechanism is mainly used in older, heavy-duty fans & industrial fans.

The mounting mechanism is one of the essential parts of a ceiling fan because if this mounting mechanism does not fit properly to the ceiling, there will be a chance of falling off the fan.

Fan Blades

Fan blades are the wing of the ceiling fan that extends outward toward the center of the fan. The blades are made of aluminum, plastic, steel, or wood. Aluminum fan blades are lighter in weight, which improves the efficiency of a ceiling fan.

Depending upon the ceiling fan, it has 3 or 4 fan blades. 4 4-blade fans provide better air circulation than 3-blade fans. This fan blade is 120 degrees apart and positioned at 12 degrees; either drag air upwards or push air downwards.

Ceiling Fan Working

In the winter season, fan blades are to be set in a clockwise direction to drag the air upward and circulate the warm air in the room. So the room feels warm and more comfortable.

In the summer season, fan blades are set in an anti-clockwise direction to push the air downward to create a cool breeze without altering the temperature, and we will get a cold breeze.

Fan Blade Bracket

Fan blade brackets, referred to as fan blade hinges, are generally made of metal. The function of the fan blade bracket is to attach the fan blade to the center part of the fan. This fan blade bracket is fastened by bolting or riveting with the fan blade.

Down Rod

A down rod is also called a suspension rod. This down rod is a rigid and hollow galvanized pipe. The diameter and length of the down rod depend upon the type and design of the ceiling fan.

The longer the size of the down rod, the lower the height of the ceiling, and vice versa.

One end of the down rod is bolted at the position and is attached to the motor housing. It absorbs the suspension caused by the motor. In contrast, another end of the down rod is connected to the mounting mechanism.

Pull Cord

A pull cord is sometimes called a pull chain. It is the most used part of the ceiling fan. A pull cord or pull chain can be made of superior metal or thick fabric string.

A pull cord is placed down from the ceiling. So the user can smoothly grab it. The function of the pull cord is to switch ON/OFF the fan, increase or decrease the speed, or change the direction either clockwise or anticlockwise.

Some fans come with several chains, and some come with only one chain that does all functions.

A pull cord is often used as part of a ceiling fan and can easily break down. This pull cord needs much maintenance and is easy to repair.


The flywheel is the component that connects the fan blade bracket to the motor. Generally, the flywheel material is rubber, plastic, or sometimes metal.

Due to its repetitive use, there are chances of deterioration, which causes the falling up of ceiling fans and harms humans.


A lamp is an extra part of the ceiling fan and is available in some new and modern ceiling fans. This lamp is at a point where all fan blades meet and are in a downward direction. It is mainly used in the bedroom to glow the aesthetic.
