220V Cooling Fan fan rotation principle

"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 "dota2雷竞技下载 " 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.
