Why Choose a DC Fan?

  • Email

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.

  • Midway Eco Ceiling Fan by Emerson

    The Emerson Midway Eco Ceiling Fan features aerodynamically designed blades that move up to 40% more air than standard blades, integrated fluorescent light, high efficiency DC EcoMotor. Offers 6 forward and 6 reverse speeds.

  • DC60 Ceiling Fan by Monte Carlo

    Refined style, clean lines and Monte Carlo's "Extreme Green" DC motor technology. The DC motor used is 300% more energy efficient than standard AC motor ceiling fans, which translates into significant savings on energy costs. Offers 7-speed functionality, including a reverse setting designed for winter use (to help recirculate warm air without causing a draft).

  • Rivetta Ceiling Fan by Kichler

    A modern design with modern efficiency. Sleekly designed for bedrooms and large kitchens, the Kichler Rivetta Ceiling Fan features a high efficiency DC motor made even more efficient by the specialized blade design. Six forward and reverse fan speeds and the optional energy efficient fluorescent light are controlled by the included Cool Touch remote control.

The current manufacturers of DC ceiling fans include:

Emersonintroduced their DC EcoMotor back in 2009 with the contemporary Midway Eco Ceiling Fan, making it three times as efficient as a typical ceiling fan. The technology has proven so successful that Emerson Fans introduced two more energy efficient fans in 2011 that also use the EcoMotor.

Fanimation When it comes to DC fans, Fanimation offerings run the gamut of design styles, ranging from the traditional Keistone Ceiling Fan to the modern Landan Ceiling Fan. In addition to using DC motors, Fanimation also incorporates energy efficient LED lamping for truly green fans. They are particularly excited by DC technology, so their selection of DC fans is sure to grow soon.

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.
