BLDC Ceiling Fan Vs Normal Ceiling Fan: What’s the difference?

The fundamental difference between BLDC ceiling fans and ordinary DC ceiling fans is the commutation technology used in their operation. A commutation is primarily a technique for determining the direction of the current within a motor to control the motility movement. The operating rule inside the physics completes the computation in an extremely BLDC motor because there are no brushes in the motor.

Durable motor

While a brushed motor’s commentators would suffer wear and tear over time as a result of mechanical contact, a brushless DC motor does not suffer from this problem, making the motor far more durable for long-term operation.

About BLDC technology

If you want to understand BLDC technology in layman’s words, it is a combination of Permanent Magnets & physics that allows it to achieve the level of potency or performance it does. The stator coil as well as the rotor of an induction fan is both equipped with coils/windings.

Why choose BLDC ceiling fan over normal fan?

An electric flux is formed when current is passed through stator coil winding of the generator. Depending on how the stator coil is arranged, this current passes through the coil and into the battery. A force field is created during a sequence to establish a motility moment. Everything is completed during the sequence. The rotation of the motor is caused by the conductance of the current that flows through the coil in the rotor.

Controller for BLDC Motor

In most cases, a controller is required for the BLDC motor. Except for the induction motor, it is only required for the variable speed requirements. A slip frequency is used in an induction generator to make the motor run at a lower intensity than the mechanical device, and the slip frequency increases with the load placed on the motor, whereas no slip frequency is used between the mechanical device and rotor frequencies.

The frequency of an inductive fan is regulated by a regulator that can be found in two different types: electronic and mechanical. Resistance-based regulation is used in this case, and the resistance of the regulator is modified to adjust the amount of voltage applied to the fan.

 These regulators are particularly inefficient since a great deal of heat is dissipated as a result of the resistance, resulting in power losses. For the most part, the trendy regulator is simply an on/off switch for an electronic device that is constantly slicing the voltage and, as a result, altering the fan speed.


One of the windings in the commutation system is electrified to potential power (current entering the winding), the other winding is activated to negative power (current exits the winding), and the third winding is in an extremely non-energized state. The connection between both the force field formed by the stator coils and the permanent magnets results in the creation of force

If all goes according to plan, the height force will occur once these two fields are 90 degrees apart from one another and fall off as the fields travel along. To keep the motor operating, the force field created by the windings must shift position as the rotor travels to cope up with the field created by the stator coils.

Energy-efficient BLDC Fans

Because the new BLDC fans have been approved with an Energy Efficiency Rating of 5-stars by the Ministry of Energy Efficiency, they consume less energy while maintaining on-air delivery. The latest Anchor fans have such an energy consumption of just 30W, even at their highest speed, and provide air supply of 230 CMM

The fans are equipped with a simple remote control that allows for zealous sleep mode selections of two hours, four hours, or eight hours, as well as an auto-off feature for added convenience. This variety of indoor air quality fans is temperature sensitive, assisting in the production of cold air that creates a natural, comfortable, and relaxing environment. While conserving energy, the new Energy Saver BLDC Fans are available in a variety of colors to complement any decor.

Normal Fans vs. BLDC Fans

This table should assist you in understanding the differences between regular fans and fans powered by brushless direct current motors.

210 watts27 watts
16 watts16 watts

As a result, as compared to traditional ceiling fans, the BLDC motor fans utilize far less electricity than the latter. As a result, we will translate this power savings into absolute values to better appreciate how the Brushless dc fans might save you money over the long term.

Fans run for around 15 hours per day, seven days a week on average. Using this premise, let us examine the economics of conventional fans and brushless direct current fans (BLDC motor fans).

The following table illustrates that you will recoup the difference in price between the 2 fans within 2 years.

Other than the reduction in electricity consumption, there are several other advantages to using BLDC Motor fans, including the following:

These fans are equipped with a remote control, which makes it simple to turn on and off the fans.

When you purchase these BLDC motor fans, you will receive a Timer and a Sleep mode, which will allow you to set a specified time restriction (number of hours) for when you sleep.

After the predetermined time has passed, the technology progressively reduces the fan’s speed. It helps you to conserve even more electricity than you would otherwise. At low speeds, the amount of electricity it consumes may be shown on the screen. You are not required to get up in the middle of the evening to adjust the regulators.

It has been demonstrated that BLDC fans are particularly energy efficient in this manner.
