60mm High Pressure Motor Dc Blower Fan

According to Ampere’s right-hand rule, a conductor passes current and a magnetic field is generated around it. If the conductor is placed in another fixed magnetic field, it will generate attraction or repulsion, causing the object to move. Inside the fan blade of the DC fan, a rubber magnet filled with magnetism is attached. Surrounding the silicon steel sheet, the shaft is wound with two sets of coils, and the Hall induction component is used as a synchronous detection device to control a set of circuits that make the two sets of coils wound on the shaft work in turn. The silicon steel sheet produces different magnetic poles, and the magnetic poles and the rubber magnet generate repulsive force. When the repulsion force is greater than the static friction force of the DC blower, the fan blade rotates naturally. Because the Hall sensor components provide synchronization signals, the fan blades of the DC blower can continue to operate. As for the direction of rotation, it can be determined according to Fleming's right-hand rule.
