How can India save 3MW per hour in 2021? | Fanzart Explains

Have you decided on being more conscious about your energy consumption in 2021? If you don’t know where to start- just take a look around your daily electrical appliances. What do you think would consume the most energy on a daily basis? An often-neglected item can be right above you- yes, we’re talking about those power-hungry ceiling fans!

Typically, a ceiling fan consumes around 80 Watts of energy, which is more than that of a standard tube light (55 Watts). Some older and larger fans can even draw up to 95-110 Watt, which are not only inefficient for your home but also detrimental to the environment.

Fans are usually on all through the day, and night, throughout all seasons. This makes it a vital consideration point when it comes to energy efficiency and would directly impact you, or your client’s electricity expenditure.

BLDC motor fans (Brushless Direct Current Motors) technology is in vogue today, which allows for a smart sustainable switch from the standard induction-motor consumption present in traditional fans. This relatively-new technology can save one up to 60% when it comes to energy consumption in terms of ceiling fans.

Now, let’s understand the basic’s of how this works, from a technical point of view.

Rotor : In bldc ceiling fans,  permanent magnets are used in the rotor.

Stator : Copper winding is used in the stator that  produces the magnetic flux after electricity is supplied to it.

The BLDC Motor fans have permanent magnets instead of electromagnets found in a conventional induction motor. There are no coils, and it is the permanent magnet that rotates. It produces a DC (Direct Current) magnetic field instead of AC magnetic field (that is produced by passing AC current through an electromagnet). This magnetic field interacts with the magnetic field of the Stator to generate motion. The current in the Stator’s electromagnet can be varied to change the speed of motion.

To understand this further, when the two same polarities (Ex S & S, N & N) take place on the rotor and the stator, magnetic force pushes the rotor to create rotational movement. So for continuous rotation in the rotor, the polarity keeps changing in the stator, so that every time the same polarity would take place on the rotor and stator,  and thus it would be continuously moving. An electronic drive is used for continuous change in polarities in the stator.

This even allows for smaller motors to produce torque (rotational speed) consistently, with the advantage of feedback mechanisms being implemented to provide for controllability. It is this precision control that reduces energy consumption and heat generation, and—in cases where motors are battery powered—lengthens the battery life.

A BLDC motor with three coils on the stator will have six electrical wires (two to each coil) extending from these coils. In most implementations three of these wires will be connected internally, with the three remaining wires extending from the motor body.

It’s simple yet efficient mechanism is what facilitates for a sleeker and thinner motor, while having a long operating life, producing lesser noise, while most importantly, staying energy efficient.

Switching your old fan would do you, and the world good. It’s the smarter way to design a home that’s suited for the future, period. If all of India makes this sustainable switch, we could save India 3 MW per hour!

Our luxury designer fans ensure that the look of your client’s home does not get compromised while providing you artisanal options that would appeal to their inner Greta Thunberg. Our fans draw 28-35 Watts, depending on the design style, blade pitch, and blade length.

BLDC motor fans are quieter too, which is yet another reason for your clients to sleep peacefully, knowing that they have done their bit to do save the environment. These types of motors make the fan long-lasting too. Coupled with our unique Summer-Winter feature, this makes Fanzart the undisputed choice when it comes to selecting a designer fan, for your designer home.
