DC Fan Operating Principle

According to the amp right hand rule: conductors by currents, generates a magnetic field around it, if the conductor on another in a fixed magnetic field, then the attraction or repulsion, resulting in motion. DC fan fan blades inside, together with a filling of magnetic rubber magnets in advance. Surround the whizzer, the axis part winding two coils, and as synchronous detection device using Hall sensors, controlling a group of circuits, the circuit winding two coils of an axis of rotation. Whizzer produce different magnetic poles, which absorb repulsion magnetic poles and rubber magnet. When the repulsive force when the static friction is greater than the fan, fan blade natural turned. Provides synchronous signals that Hall sensors, fan to continuous operation, as its orbit, according to Fleming right-hand decision.
