220V Cooling Fan operating principle

Date: 2015-1-19   Click: 1589 Times

"220V Cooling Fan" right-hand rule according ampere, the conductor through the current produces a magnetic field around, if this conductor is placed in another fixed magnetic field, will produce suction or repulsion, causing objects to move. DC fan blades inside, attached to a pre-filled with the magnetic rubber magnets. Surrounded by silicon, axial part of the winding two coils, and "220V Cooling Fan" Hall sensor component as synchronous detection device, controls a group of circuit which makes the axis of the two coils wound in turn work. Silicon have different magnetic poles, the magnetic pole and the rubber magnets generate repulsive force absorption. When the suction fan repulsion of static friction is greater than the lice, "220V Cooling Fan" natural rotation of the blades. Due to the Hall sensor component provides a synchronization signal, the fan was able to continue functioning, as its direction of rotation, right-hand rule to follow Fleming decision.
