Inflatable Air Blower composed by what?

In the "Inflatable Air Blower" blades inside, attached to a pre-filled with the magnetic rubber magnets. Surrounded by silicon steel, two sets of coils wound around the axial center portion, and a Hall sensor component as a synchronization detection means for controlling a set of circuits, the circuit of the two sets of coils wound around the axis of rotation of work. Silicon have different magnetic poles, the magnetic pole and the rubber magnets generate repulsive force absorption. When the suction repulsion is greater than the "Inflatable Air Blower" static friction, the blades rotate naturally. 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 decided to direct "Inflatable Air Blower" is to provide the use of a DC power supply: DC motor has a stator and two major components of the rotor, there is between the stator poles at an angle in the stator and rotor magnetic attraction to each other, the rotation of the motor. Change brush seat, you can change the direction of the angle between the stator and rotor poles, thereby changing the direction of rotation of the motor.
