Note: I don’t know it is for you,  but the person who is having very good knowledge about the financial planning for them this is best product.

 

a)     Why everyone change to BLDC Fan?

To reduce the electrical power consumption, upto 65 % more efficiency compare with traditional fan and increase the inverter life 3 times more.

 

b)    What BLDC Fan?

BLDC stands for Brushless DC motors. The BLDC motor is a synchronous motor powered by a DC electric source. It uses an integrated inverter power supply to produce an electrical signal to drive the motor. There are two types of motors, the Brushed Motors, and the Brushless Motors. The Brushless Motor is a recent invention whereas the Brushed Motor is in existence for over a century.

c)     Working principle of BLDC Fan?

BLDC motor works on the principle similar to that of a conventional DC motor, i.e., the Lorentz force law which states that whenever a current carrying conductor placed in a magnetic field it experiences a force. As a consequence of reaction force, the magnet will experience an equal and opposite force.

The housing supports the windings in the BLDC motor. It explains why you can cool the motor by conduction. It does not require any airflow for the internal cooling thereby implying that the motor parts have full protection from dirt and other foreign matter. The Super-Efficient fans of today use these BLDC motors instead of the traditional ones

 

 

d)    What are the type of BLDC Motor?

There are three classifications of the BLDC motor: single-phase, two-phase and three-phase. This discussion assumes that the stator for each type has the same number of windings. The single-phase and three-phase motors are the most widely used.

 

e)     What is BLDC motor drive?

Definition: The self-controlled variable frequency drive employing a sinusoidal PMAC (Permanent Magnet Alternating Current) motor is called brushless DC motor drive. The brushless DC motor drive has some advantages like practically they require no maintenance and have a long life.

 

f)      What is the BLDC motor application?

         Brushless DC Motors (BLDC) are used for a wide variety of application requirements such as       varying loads, constant loads and positioning applications in the fields of industrial control, automotive, aviation, automation systems, health care equipments, etc. Some specific applications of BLDC motors are

1)     Computer hard drives and DVD/CD players

2)     Electric vehicles, hybrid vehicles, and electric bicycles

3)     Industrial robots, CNC machine tools, and simple belt driven systems

4)     Washing machines, compressors and dryers

5)     Fans, pumps and blowers

 

 

 

 

 g)     What are the advantages of BLDC                                                  motor? 

1)     It has no mechanical commutator and associated problems

2)     High efficiency due to the use of permanent magnet rotor

3)     High speed of operation even in loaded and unloaded conditions due to the absence of brushes that limits the speed

4)     Smaller motor geometry and lighter in weight than both brushed type DC and induction AC motors

5)     Long life as no inspection and maintenance is required for commutator system

6)     Higher dynamic response due to low inertia and carrying windings in the stator

7)     Less electromagnetic interference

8)     Quite operation (or low noise) due to absence of brushes

 

h)    Disadvantages of Brushless Motor

1)     These motors are costly

2)     Electronic controller required control this motor is expensive

3)     Not much availability of many integrated electronic control solutions, especially for tiny BLDC motors

4)     Requires complex drive circuitry

5)     Need of additional sensors

 

i)      How do you control a BLDC motor?

First, the BLDC motor is usually a three-phase system; so, it has to be powered by a three-phase power supply. Second, the rotor position must be known at certain angles in order to align the applied voltage. The most common way to control a BLDC motor is to use Hall sensors to determine the rotor position

 

j)       The history of Brushed and Brushless Motor?

Brushed DC motors have been used since 1856, and are still often used for electrical propulsion, cranes, paper machines and steel rolling mills. However, since their brushes wear down and require frequent replacement, brushless DC motors using electronic speed controller devices have displaced brushed motors for many applications. Brush wear became a significant drawback due to intense application demands and high-electric discharge noise (aka ESD, especially in aerospace applications), and a new motor was born.

Brushless motors are significantly newer and invented during the advent of electronics innovation. Advancements in solid state technology in the early 1960s resulted in the invention of the first brushless DC (BLDC) motor in 1962, what T.G. Wilson and P.H. Trickey called a “DC machine with solid state commutation.” The key element of the brushless motor is that it requires no physical commutator, making it the most popular choice for computer disk drives, robotics, and aircrafts

 

k)     How long will a brushless motor last?

1,000 to 3,000 hours

If you are looking for a motor with a long life expectancy, consider a brushless motor. Brushed motor life is limited by the brush type and can attain 1,000 to 3,000 hours on average, while brushless motors can attain tens of thousands of hours on average, as there are no brushes to wear.

l)   Normal Fans vs. BLDC Fans Power consumption

This table should help you understand the difference between the traditional fans and the ones with the BLDC motors.

The speed of the Fan	BLDC Motor Fans	Traditional Ceiling Fans
1	3 Watts	16 Watts
2	7 Watts	27 Watts
3	12 Watts	45 Watts
4	18 Watts	55 Watts
5	28 Watts	75 Watts

m)  Saving of BLDC Fan

The fans run for about 15 hours a day on an average. With this assumption let us compare the economics of the regular fans and the BLDC motor fans.

	Regular Fan	BLDC Motor Fan
Approximate Cost Rs	1600	3300
Consumption of power	75 Watts	28 Watts
Hourly Consumption	0.075 units	0.028 units
Daily Consumption	1.125 units	0.42 units
Yearly Consumption	410.625 units	153.30 units
Costs (Rs  6 per unit)	2463.75	919.80

 

 

Other than the savings in consumption of electricity, you have additional benefits to the BLDC Motor fans.

These fans come with a remote control unit thereby allowing you to switch on and off the fans easily.

These BLDC motor fans come with a Timer and Sleep mode that will enable you to set a specific time limit (number of hours) while sleeping.

The technology reduces the speed of the fan gradually after the set time. It enables you to save more electricity. You can see the amount of power it consumes at low speeds. You do not have to get up at night to control the regulators.

Thus, we have seen that the BLDC motor fans are extremely energy efficient.

o)    Here’s How to Set Fan Rotation according To Seasons

Not many people know but the ceiling fan rotation should ideally be different for different seasons. Why? Because it helps to maintain the room temperature better.
So, to start with, some ceiling fans can work in two directions: clockwise and anti-clockwise. The direction of the rotation blows air upwards and downwards respectively. While normally, all the fans are set to blow air downwards, their rotation being anti-clockwise, there are some fan that offer the reverse rotation, feature too.
So, which rotation is best for which season? Read on to know.

Fan Rotation In Summer:
During summers, we need our fans to keep us cool, don’t we? So, during summers, it is best to have the fans spin anti-clockwise. This direction of rotation causes a downward draft of air, directly blowing air across the room. Due to the fast circulation of air in the room, a breeze effect is created and we feel cooler.

Fan Rotation In Winter:
In majority of regions of India, the winters are so cold that we rarely use fans during winter. But then there are some rare days when you feel cold and want air circulation but not cooling. So, when those rare days come, make sure your fan is spinning in a clockwise direction. Clockwise rotation of fan blows the air trapped near the ceiling downwards. Why is the trapped air important? Because warm air is lighter than cool air. So during winters, the warm air inside the room keeps on saturating near the ceiling, while the air below makes us feel cold. Use your fan in clockwise rotation to keep your room warm. Additionally, you can also turn off the heater and save on your electricity bill.

How To Check The Fan Rotation Direction?
Use this easy method to know the direction. Stand under the fan and notice the direction of fan blades. When the fan is in an anticlockwise rotation, the fan blades should be spinning from your right to your left. Similarly, if the fan is spinning from your left to your right, it means the fan is set for clockwise rotation.
