Tiny Cooling Fan operating principle

Time:2014-12-9 Click:512Times

"Tiny 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, "Tiny Cooling Fan" 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 magnetic poles, the magnetic pole and the rubber magnets generate repulsive force absorption. When the suction fan of repulsion greater than the static friction, the natural rotation of the blades. Due to the Hall sensor component provides a synchronization signal, "Tiny Cooling Fan" fan was able to continue functioning, as its direction of rotation, right-hand rule to follow Fleming decision.
