SC-1132 Hall gear sensor DC brushless fan strong resistance mechanical stress Hall chip

The working principle of DC fan with hall chip

A conductor passes through an electric current to generate a magnetic field. If the conductor is placed in another magnetic field, it will generate attraction or repulsion, causing the object to move. Inside the DC fan blade, a rubber magnet surrounds the silicon steel sheet, and the shaft is wound with two sets of coils. The Hall chip is used as a synchronous detection device to control a set of circuits that make the two sets of coils wound on the shaft take turns. jobs. The steel sheet produces different magnetic poles, and the magnetic poles and the rubber magnet generate repulsive force. When the repulsive force is greater than the static friction force of the DC fan, the fan blades of the DC fan rotate naturally. Because the Hall chip component provides the synchronization signal, the fan blade can continue to operate, which is the working principle of the DC fan.

01.The SC1132 Hall-Effect switch series is monolithic integrated circuits with tighter magnetic
specifications, designed to operate continuously over extended temperatures to +150℃, and are
more stable with both temperature and supply voltage changes. The negative compensation slope
is optimized to match the negative temperature coefficient of low cost magnets.
02.Each device includes a voltage regulator for operation with supply voltages of 3.8 to 40V volts,
quadratic Hall-voltage generator, temperature compensation circuitry, small-signal amplifier,
Schmitt trigger, and an open-collector output to sink up to 40mA.
