Origin and History of BLDC Motors
BLDC technology was first discovered in the 1960s by T.G Wilson and P.H Trickey. Earlier, this technology, or BLDC motors, was used only in big machinery and for industrial use due to its energy efficiency. However, this technology is used in big to small electrical appliances today.
Applications of the BLDC motors
Ceiling Fans
Air Conditioners
Electric vehicles
Refrigerator
Lab Equipments
Robotics
Pumps
Blowers
Washing machines
What is the difference between BLDC motors and normal motor
BLDC Motors | Normal Motors |
Brushless technology | Brushed technology |
Energy efficient | Not energy efficient |
Energy input and output are the same | Energy output is low as compared to the input given |
Do not overheat | Generate heat |
Do not produce carbon footprints | Produce carbon footprints |
Wide voltage operation | High voltage operation |
BLDC technology in a ceiling fan
Traditional ceiling fans usually work on conventional motors, but today, the BLDC motor in ceiling fans is overtaking the market. The BLDC ceiling fans surely create a buzz in the market due to their unique features.
Features of BLDC motor ceiling fans
The BLDC ceiling fans are energy-efficient. They consume 60-70% less energy than normal fans.
The BLDC fans do not generate heat while operating.
The amount of input and output energy is the same in the BLDC ceiling fan.
The BLDC fans have low voltage operation, which gives the wide voltage area functionality.
The BLDC ceiling fans are inverter-friendly fans.
The BLDC ceiling fans do not produce carbon footprints while operating, so it is a greener and a sustainable option.
The BLDC ceiling fans have a brushless technique and do not generate heat,
which prevents the sound of humming, creaking, etc., even at high speed.
Comparison table depicting the energy consumption of BLDC and Non-BLDC ceiling fans
Speed of fan | Normal fan energy consumption (in watts) | BLDC fan energy consumption (in watts) |
1 | 17 watts | 7 watts |
2 | 28 watts | 10 watts |
3 | 48 watts | 15 watts |
4 | 59 watts | 21 watts |
5 | 80 watts | 30 watts |
This table gives us the difference between the consumption of energy of BLDC vs Normal Fan
What is Copper Winding in the Ceiling Fan Motors?
Copper winding is a type of conductor made with high-quality copper commonly used in electrical applications.
In a ceiling fan, a copper winding is a wire coil of copper in the fan’s motor which is an important element in the functioning of the fan.
The fan has mainly two components- the rotor (rotating part) and the stator (stationary part).
This copper winding is present in the stator through which current passes and creates a magnetic field.
The rotor contains permanent magnets that interact with the magnetic flux through the copper winding, allowing the fan to rotate.
Traditional ceiling fans used to be designed with aluminium wire winding. But now, some fans based on BLDC technology come with copper winding motors for efficient and high performance.
Difference between Copper Winding and Aluminium Winding
There are various differences between these two windings. Have a close look at them.
Copper Winding | Aluminium Winding |
Stronger | Less stronger |
Excellent electrical conductivity | Lower electrical conductivity |
Durable | Shorter life |
Expensive | Cheaper |
Heavier in weight | Lighter than copper |
Oxidised-resistance | Oxidised quickly |
BEE Star Rating
BEE stands for bureau of energy efficiency and to have BEE star-rated products or appliances you need to enroll in the BEE star labeling program. As per the new law now every ceiling fan either made in India or from outside needs to be a BEE star-rated labeled fan.
Each star depicts the energy consumption of an electrical appliance. The more the star rating of an appliance more it indicates the energy efficiency or saving
Conclusion
Searching all about a particular technology can be a task, but no more, as we have covered all the possible information about the BLDC technology in this article. We hope this can help you understand the technology better and also help you to choose the perfect fan for you.
