The basic principle of fan


the principle of electromagnetic induction, magnetic field force through the current, for the size of the force meet the running mechanism of lenz's law the cooling is more groups of coil ( The stator) When the electricity to its outer ring magnet ( Rotor) Produce reaction, so that the fixed on the blades spin, outside the ring magnet because of the rotation for a week, need to change the direction of the current in the coil, to adapt to the rotation and the change of the magnetic polarity, so the current direction of the coil and the polarity of the applied voltage transformation driven by control IC, according to a hall sensor to detect the magnetic field direction to adjust, each detected a N pole magnetic field, driver IC for each coil respectively applied voltage to determine the different direction, and ensure that the overall direction of force constant in the clockwise direction ( Or counterclockwise) 。 Control driver IC to replace traditional way has a brush to switch current polarity is that the advantages of compact structure design, can be used to enhance the current contact reliability, eliminating the traditional motor polarity when switching the electrical noise. Wenling city tong chi auto air conditioning manufacturing co. , LTD. , specializing in the production of radiator cooling fan.
