1. "220V Cooling Fan" control part: magnetic Hall effect switches, transistors and resistors and other elements. Its function is to control the stator coil winding current direction changes.
2. "220V Cooling Fan" winding part: silicon steel, enameled wire, and the upper and lower insulation frame composition. Wherein the silicon steel poles function is responsible for export, in order to determine N, the strength of S, and the winding determine the directionality of the magnetic field lines, including N, S pole and control signals, changing the winding polarity, push magnetic frame operation, to achieve the purpose of acting.
3. "220V Cooling Fan" fixed magnetic field components: a fixed magnetic field provided by the magnetic rubber to produce power when used in rotation.
