"220V Cooling Fan" The main feature is the AC motor, which works by the force of the coil is energized to rotate in a magnetic field, so that the fan blades rotate. Electrical energy conversion is the main form of energy into mechanical energy, and because the coil has a resistance, so that there is an inevitable part of the electrical energy to be converted into heat. General "220V Cooling Fan" (with 220V AC) motors are capacitive phase single phase motor. It has two windings: primary winding (run winding); secondary winding (start winding). "220V Cooling Fan" primary winding directly connected to 220v power, after a series capacitor connected to the secondary winding 220v power.
