Zusammenfassung: | The utility model relates to a novel reactance ceiling fan speed regulator. The existing speed regulator has the disadvantages that the rise of the rotary speed of the ceiling fan is slow, energy consumption increases, a motor is easy to generate heat, and the service life is influenced, when the speed regulator is started at a low block. When the speed regulator is started at a high block, though the speed regulator can be started quickly, the speed regulator is run at a medium-low block by people. So the procedure is complicated and time is wasted. The utility model adds a control circuit and an automatic time delay circuit which is composed of an integrated circuit 555 and a peripheral circuit. The foot 2 and the foot 6 of the integrated circuit 555 are connected and are respectively connected with a time delay resistor and a time delay capacitor. The foot 3 of the integrated circuit 555 is connected with a base electrode of a triode through a resistor. The emitter of the triode is connected with a relay. The other end of the relay is connected with the foot 1 of the integrated circuit 555. |
