"220V Cooling Fan" works by rotating the motor in the principle of electromagnetic induction. Electric motor with AC current to produce a rotating magnetic field varies over time, thereby enabling rotation of the rotor made of silicon, which led the blades rotate. Or energized coil in a magnetic field by the force of the rotation. "220V Cooling Fan" form of energy is transformed: the main electrical 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 internal energy. Since "220V Cooling Fan" blades rotating air being squeezed, causing the air flow to form a wind direction of the air flow direction with the inclination and the rotational direction of the fan blades about.
