1. "220V Cooling Fan" control section: by the Hall effect magnetic switches, transistors and resistors and other elements. Its function is to control the direction of the stator coil winding current changes.
2. "220V Cooling Fan" motor winding section: from silicon steel, wire and down insulated frame composition. Wherein the silicon steel function is responsible for the export poles, in order to determine N, S of the strength, and determines the magnetic field lines of the winding direction, comprising N, S poles and the control signal, changing the polarity of the winding, magnetic frame pushing operation, achieve the purpose of acting.
3. "220V Cooling Fan" fixed magnetic field components: a fixed magnetic field provided by the magnetic glue to produce power when used in rotation.
