Do DC ceiling fans use less energy?
There are more and more DC ceilings fans being introduced to the Australian ceiling fans market. As a general rule, DC ceiling fans usually use less energy than other ceiling fans. However, many people are asking what ‘DC’ fans actually are, what advantages DC motor ceiling fans have, and whether DC ceiling fans will really help them save energy, and in turn, save money.
What is the difference between DC vs AC ceiling fans?
DC means direct current, AC means alternating current. AC changes direction 50 times a second whereas DC doesn ’t change at all. Both have been around for a long time and DC was used in not only batteries but for transmission too in the late 19th century being pushed by Edison. However, DC experiences a large drop in power as you got further up the wire away from the source which is a serious practical limitation. Then along came the famous Serbian inventor Nikola Tesla who developed the first AC motor and transformer which he licensed to Westinghouse and eventually AC won the day in the “current wars” that took place between the three large US electric companies.
How much less energy does a DC ceiling fan use?
A DC ceiling fan uses typically 70% less energy for the same airflow as a conventional AC ceiling fan. They have better controls of different speeds (more speed settings typically 6) and are a smaller size for a given output of air movement.
How do ceiling fans work?
Ceiling fans have been primarily driven by AC current using capacitors to start the motor and control the typical 3-speeds. In the early 2010’s a new form of more efficient ceiling fan control emerged whereby the AC current was converted into DC which meant far more precise control of the voltage waveform enabling typically 6-speed control. The DC current is converted back into AC before being fed to the motor itself, the whole thing being termed a motor-driver.
Why is AC important for long distance power lines?
The other major benefit of AC is that it can be used with capacitors and inductors in electronic circuitry to enable the tuning of circuits to take place.
What is DC motor?
DC motors use permanent built-in magnets to attract and repel a rotor around an axis coupled with inverters. DC ceiling fans also use a newer type of “brushless” DC motor that use electrically commuted motors (ECM) that is even more efficient and also very quiet thus making ceiling fans great for bedrooms.
Who invented the AC motor?
Then along came the famous Serbian inventor Nikola Tesla who developed the first AC motor and transformer which he licensed to Westinghouse and eventually AC won the day in the “current wars” that took place between the three large US electric companies.
Do ceiling fans need a DC power supply?
When most people first look at DC ceiling fans they assume wrongly that they require a DC power supply. This is not the case as the motors use a driver that sits on top of the motor to convert the mains AC into DC and then back to AC again to feed the motor itself, which is in fact AC!
How are AC and DC fans different?
AC and DC fans are differentiated by the type of electric current they use. Ceiling fan electric motors run on either Alternating Current (AC) or Direct Current (DC). The difference between them is that AC is powered by an electrical charge with reverse flow direction and DC is working with the constant flow.

How does AC and DC work?
Nowadays, both work in tandem. AC runs above us on wires, like the lines of an empty diary that terminate at your house . The AC voltage then is converted to DC with a rectifier, like the adaptor that your charger contains , to power household devices, such as bulbs, lamps and other appliances. The War of Currents might not be as dramatic as it once was, but it still subtly exists. If you need to get one of the AC DC power supply to feel free to check it out here.
What are the advantages of AC over DC?
The ability to carry power across long distances was the most important advantage of AC over DC, regarding which houses and buildings discontinued DC power in the 19th century. In 1893, General Electric was chosen to power The Chicago World’s Fair with DC, which would cost an exorbitant $554,000. However, George Westinghouse intervened and promised to power the fair for only $399,000 with Tesla’s AC. Three years later, Niagara Falls Power Company, seduced by AC’s amenities, awarded Westinghouse the right to generate power from Niagara Falls and illuminate all of Buffalo, New York. AC obliterated DC once and for all. Then, a few decades later, the transistor was born.
What is alternating current?
Alternating current is a type of current in which the electrons periodically switch directions back and forth. It is based on the principles devised by Michael Faraday in 1832 when he illustrated his dynamo electric generator. Despite being so celebrated, DC exhibited a major problem — transmitting it over longer distances was really difficult. The wires lost power and had to be rejuvenated using additional circuitry. Furthermore, upgrading or downgrading DC voltages also required complicated circuits.
What is the AC versus DC debate?
The AC versus DC debate personifies the War of Currents, as it is now called, in which the two giants of electric power were embroiled in the late 1890s. Thomas Edison, the proprietor of Direct Current, was so threatened by Tesla’s invention that, in order to discredit Alternating Current, he resorted to falsely misleading Americans. Apprehensive about losing his royalties to this new technology, Edison went so far as to electrocute an elephant to show Alternating Currents’ fatal dangers.
Why does AC transmission slow down?
The transmission slows down due to these resistances, consequently diminishing its efficiency. In fact, the losses dispersed in its vicinity form the basis on which wireless power transfer mechanisms are structured. AC radiates some of its energy, which can be conveniently concentrated in a region by coiling the wire in a suitable way.
What is a ceiling fan?
A ceiling fan is a compact mighty little device that just spins. That’s all it does is spin in one direction to force air around your room. The simplicity alone should win awards, but for that reason, it’s efficient with purpose. AC units just seem to take-up space, electricity, and make plenty of noise.
Why do ceiling fans cool down?
When hot air is pushed downward towards cool air, the hot air reacts since it has more water molecule content. In typical weather conditions, this is how rain occurs. A ceiling fan does a miniature version by making air significantly cooler. This is a natural effect called downdraft evaporation.
What is a ceiling fan, and its cooling principle?
The very nature of a ceiling fan is a practical way to have room ventilation without blocking a work area. At least this is how the original invention was intended to be used. Factory employees who worked around heat and machinery could enjoy a direct flow of air overhead. The very first Hunter Ceiling Fan was an invention that surfaced in 1886 was used exactly for this purpose. Nearly a decade passed before it would be sold as a product for the public.
