How Does a Table Fan Work? Decoding the Working Principle

Table fans have been in the market for a long time, but nowadays people are developing new motors to make them more energy efficient. What’s new in the modern table fan is  technology, efficiency, and appearance, which make it an attractive and convenient option to invest in. The BLDC motor has recently entered the fans industry with a bang with its promise of saving money on your electricity bills. However, before purchasing the best portable table fan for your home, you must understand its working principle. 

Working Principle of a Table Fan

If you want to invest in a table fan for your home, learning about the working principle of a table fan can be helpful in case anything goes wrong with the components.

1. Generally, table fans comprise a primary component known as the single-phase induction motor. The capacitor on the fan is used to give a starting torque to the motor, which allows the table fan to start and spin.
2. As soon as the electric current reaches the table fan motor, it immediately enters the coils of the wires, which are wrapped around the core’s base.
3. The current then flows through the wire, creating a magnetic field that exerts force in a clockwise direction.
4. This process alters the electrical energy into mechanical energy via a process called electromagnetism.
5. The motor coils begin to spin due to the clockwise directional force.
6. The table fan then taps into the spinning motion and begins rotating along with the table fan blades.
7. The table fan blades cut or slice the air and therefore result in pushing the air forward, which creates the fan’s airflow.
8. Regarding the airflow, the table fan blades are meticulously designed at a specific angle, and as the fan blades hit the air, it bounces off after the collision, carrying kinetic energy that makes you feel a gust of cool air in the space.
9. The table fan comes with an oscillating motion or perhaps a swing mechanism wherein it rotates from one side to another at more than 100° about its fixed position. This is done with the help of the gear system, which ensures a gust of cool air over a wider range.

And that’s how a table fan works, providing you with a good amount of airflow in the space you keep it. Table fans are constantly upgraded in terms of aesthetic appeal and innovation. The workings of these table fans have become more efficient and functional. Most of these changes come in terms of the material, colour, and efficiency of the table fan motor. If you’re wondering which motor is used in a table fan, there are two main types which you need to know about so you can understand which best fits your requirements. 

Type of Motors Used in a Table Fan

The table fan motor could be a single-phase AC motor or a BLDC motor. Let’s dive deeper into their characteristics.

Single-Phase AC Motor

A single-phase AC motor comprises only one table fan winding, and its rotor is of the squirrel cage type. The AC motor contains a coil that has a resistance of 100 ohms, which is usually not considered high. For example, the phase shift is split into two parts: starting winding and operation winding. What makes a single-phase AC motor a perfect pick for you?

1. Simple structure
2. Cost-efficiency
3. Convenient operation
4. Economical maintenance and repair

However, there are certain points of concern when it comes to single-phase AC motors.

1. It is not highly efficient
2. It cannot work at low voltage
3. It has low starting torque
4. It has a high starting current
5. Its speed adjustment can be difficult

We hope this article helped you understand the working mechanism of a table fan motor. To know more about the benefits of using a table fan, check out our blogs.

Considering the efficiency, aesthetic appeal, and portability, you will be able to find the best Crompton table fan for your home!

FAQs Table Fan Working Principle

1. How to check the capacitor of a table fan?

Use a multimeter to read the voltage on capacitor leads. It should read around 9V. Since the capacitor is discharging through the multimeter, the voltage will drop to 0V. If the capacitor fails to hold that voltage, it is faulty and must be replaced.

2. Which company is best for table fans?

Crompton is among the best brands if you’re searching for a high-quality table fan. The innovative technology, modern design, and incredible efficiency of these table fans will only offer you the best cooling experience in your space.
