Why Choose a DC Fan?
What's not to love about fans with DC motors? They consume up to 70% less energy and run almost silently.
For those interested in energy efficiency (and who isn’t these days?) the latest ceiling fan technology, the DC motor, is something to be really excited about.
How Do DC Fans Work?
The quick answer: The DC motor starts up when a small electric current is
passed through a magnetic field coil. The resulting magnetic force producing
the torque that turns the motor repeatedly.
The detailed answer:
The specific type of DC motor used in
ceiling fans is a brushless DC motor, (aka
synchronous DC motor). A DC motor uses an
internal array of magnets of opposing polarity.
This creates a magnetic field that creates the torque
required to rotate the motor's rotor. This process
requires less electrical energy, translating into a
70% or greater reduction in power consumption
over standard AC motors.
Other Benefits of DC Motors
This energy efficient process keeps the motor cool, effectively improving the fan's life span. Noise is virtually eliminated. And the overall assembly is much more compact than standard, making for a smaller and lighter product.
The only real disadvantage of DC motor ceiling fans is the initial cost, as they require a pricier, more complicated electronic speed controller to run. However, the price increase is not as painful as you might think and is more than balanced by the many more years of usable service.
While still relatively new, the best part for consumers is that energy efficient fans with DC motors are now available in a wide range of modern designs, conceived by an ever-growing pool of quality ceiling fan manufacturers. Depending on whatever complementary lamping they might have, the majority of these qualify as Energy Star ceiling fans.
- Odyn Ceiling Fan by Fanimation Fans
The Fanimation Odyn Ceiling Fan moves some serious air with its 7-foot blade span, while its DC motor consumes up to 70% less energy. Includes a matching cap for use without the LED light, and a remote to control its six forward and reverse speeds.
- Irene 3-Blade Hugger Ceiling Fan by Atlas Fan Company
Rustic yet modern, the Atlas Fan Company Irene 3-Blade Hugger Ceiling Fan is streamlined yet warm with solid wood blades. The sleek cylindrical housing contains an ultra-quiet, efficient and reliable DC motor. This six-speed fan is controlled via a hand-held remote that may also be mounted on the wall, and the fan’s reverse function is handled right on the remote.
- Skylon Ceiling Fan by
Monte Carlo Fans
At an impressive 170 RPM, the Monte Carlo Skylon Ceiling Fan cuts through the air like the scissor shears that inspired its design. The Extreme Green DC motor is whisper quiet as it cuts down on energy consumption, and its reversible setting helps cut heating costs in winter by circulating warm air without causing drafts. The six-speed fan includes a remote control and dimmable LED light with optional cap.
Kichler is one ceiling fan manufacturer that has jumped into the DC motor pool with both feet. Their high efficiency DC motor is seen in a large number of their most recent ceiling fan releases. Many of these Kichler DC fans also feature fluorescent lamping, making them both truly energy efficient and Energy Star qualified.
Monte Carlo ceiling fans are "created with tomorrow in mind." To that end, Monte Carlo Fans recently introduced their Extreme Green line of super efficient ceiling fans. These ceiling fans are up to 300% more efficient than standard fans, using the latest DC motor and energy efficient lighting technology. Plus, they're designed with timelessness in mind, so they'll be up and running beautifully for many, many years to come.
