Cooling Fan Manufacturer operating principle

"Cooling Fan Manufacturer" 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, "Cooling Fan Manufacturer" axis of part two coils wound, and a Hall sensor component as a synchronous detection device, controls a group of circuit which makes the axis of the two coils wound in turn work. Silicon have different poles, the magnetic field and the rubber suction magnet repulsion. When the suction fan repulsion of static friction is greater than the lice, "Cooling Fan Manufacturer" 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.
