DC Fan Motors


For 2011, manufacturers are concentrating on producing ceiling fans that offer better energy efficiency and quieter operation. In order to achieve these goals, most manufacturers are offering more choices utilizing DC motors.

DC Motors have several advantages over the traditional AC motors commonly found in previous generations of ceiling fans.


DC fan motors use less than 30% of the energy of a standard fan motor.  In fact, three DC fan motors running at high speed use the same energy as one 100 watt light bulb!  This, of course, leads to smaller energy bills.  If several thousand homes switched to fans with DC motors, it could lead to considerably less strain on power grids during the summer months.

In order to rotate the motor housing, traditional ceiling fans use electricity to magnetize the motor.  DC motors are permanently pre-magnetized, so no power is wasted in this process.  This is the major reason for the difference in energy expenditure between AC and DC motors.


Less wattage equals less heat.  Less heat equals less stress on the motor, which leads to considerably longer, more reliable operation.


DC fan motors have the wall/handheld control receiver directly on the motor housing.  This allows the manufacturer to construct the fan with a 3-wire configuration.  Older fans have the receiver near the ceiling, requiring a 6-wire setup.  Electricians will find DC fans quicker and easier to install.

Most fan manufacturers have introduced many contemporary and traditional fan styles for 2011.  Leading the way is Kichler, one of the most trusted manufacturers in residential and commercial lighting products.
