DC Fan 9141 and FS319, AH477 basic differences

"DC Fan" 9141 double coil winding, when the work is controlled by Schmitt trgger both transistors turned on and off to control the coil off (output half-wave), and 319 single-coil, starting current small, two-way type H output drive, four transistors by controlling the on-off control the direction of current in the coil (the output of full-wave). Products using air guide channel and spacers and the stator as a whole, such a simple structure, installation is easy to use. The appliance industry, machinery industry, equipment manufacturing industry and other ventilation requirements of the products are widely used in DC fan.
