Items on page:

DC ceiling fan works pretty much on the same principle as the DC motor. A DCmotor uses an internal arrangement of magnets with opposing polarity. As current passes through the coil around this arrangement, a strong magnetic field is produced. This magnetic field then creates a torque that causes the motor to rotate.

The advantages of a DC motor ceiling fan over an AC motor ceiling fan:

  • In most cases, they use less energy – up to 70% less than a standard AC fan.
  • They are generally extremely quiet.
  • They will often have more speed options, the reverse function on the remote, and are generally faster to start, stop and change speed.
  • The motor is generally more compact and lighter, which allows for a slimmer motor design.
