Tiny Cooling Fan works

In the works above "Tiny Cooling Fan" and AC fans is not the same. Conductor through the current generates a magnetic field, if the conductor is placed in a magnetic field to another, it will produce suction or repulsion, causing objects to move. In the fan inside, surrounded by silicon rubber magnets, two coils wound around the axial center portion, and a Hall sensor component as a synchronous detection means for controlling a set of circuits, the circuit of the two sets of coils wound around the axis of rotation of work. "dota雷竞技 " produce different steel poles, the poles with rubber suction magnet repulsion. 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, the fan was able to continue running. A lot of people have been very concerned about this point, I do not know the difference between real and flow fan DC fan somewhere. That we first analyzed from the "dota雷竞技 " very important bearing.
