"220V AC Cooling Fan" The main components are: AC motor. Its working principle is: energized coil in a magnetic field by the force of the rotation. 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 heat. "220V AC Cooling Fan" means a hot day so as to take cold wind fan utensils, electric drive is a device to generate airflow within the configured "220V AC Cooling Fan" is energized to rotate into natural style later to achieve cool effect.
