Explorer 60" 5-Blade Energy Efficient DC-Motor Ceiling Fan w/Limiter Brushed Steel 5EXR60BSD-L

This ceiling fan features a DC motor which, contrary to regular AC motors, uses significantly less energy to keep the fan rotating. Whilst some energy is used to accelerate the fan from stationary to active, or between speeds, once the fan has established a speed it becomes much more energy-efficient. Special magnets in the motor keep the fan rotating with very little energy expenditure. You could save upwads of $50 in energy costs over the course of a year by using this futuristic new ceiling fan technology, compared to traditional AC-motor fans.Brushed Steel Finish5 BladesBlades Finished in Silver13 Degree Blade Pitch24.14 Height x 60 WidthIncludes 6 DownrodFan Blade to Ceiling Height 17.87Up Light: 6 x 15 Watt Incandescent Candelabra BulbsDown Light: 3 x 40 Watt Incandescent Candelabra BulbsMotor Dimensions: 18mm Height x 165mm DiameterCubic Feet Per Minute of Air Flow: 6207.72 High / 4192.39 Medium / 1877.21 LowRevolutions Per Minute: 133 High / 92 Medium / 45 LowPower Consumption in Watts: 28.1 High / 9.9 Medium / 3.5 LowPower Consumption Per Cubic Foot of Air Flow: 220.92 High / 423.47 Medium / 536.35 LowAlternating Current motors use a steel/aluminum rotor and copper windings on the stator that when energized creates an electromagnet.The AC current is necessary so the poles of the electromagnet frequently change causing the rotor and stator to repel each other which causes the motor to spin.Creating this electromagnet uses a lot of energy. More copper can be added to increase power but also reduces efficiency.Direct Current fans also included magnets to help create the necessary magnetic field to spin the rotor. This means less electric energy is necessary. This also means less copper windings are necessary to create the same amount of power.Engineered with Integral Electronic Drivers. Converts AC to DC. Control the Fan's Speed by Reducing Input Voltage. Coordinates and Aligns the Location of Magnets in Relationship to Coils.Less Copper Windings than traditional AC motor modelsSame Motor Torque as AC Model
