Series connected inductor fine-tuning tap speed regulating circuit

Generally, after the ceiling fan is turned to the fifth gear (the last gear), the speed is still faster and the blowing force is stronger. As shown in the figure, another speed regulator L2 is connected in series to the speed regulator L1, and a fine-adjustable buck tap is added to realize the breeze operation of the ceiling fan. When wiring, disconnect the "4" tap of L1, and then connect it as shown in the figure. In this way, the first three gears are adjusted by L1; when Ll is adjusted to the "4" gear, use SA2 to adjust to the appropriate gear to obtain a satisfactory breeze.
