I TRIED TO CONTROL AC MOTOR USING TRIAC BUT I WAS NOT ABLE TO GET THE 220 MICROHENRY INDUCTOR CAN I PUT TWO INDUCTOR IN SERIES E.G 2 100 MICROHENRY WHICH WILL BE IN SERIES AND WILL IT HAVE ANY EFFECT SINCE IT WILL ADD UP TO 200 MICROHENRY WHICH WILL HAVE 20 MICROHENRY LESS THAN THE NORMAL VALUE.
NB IN THE CIRCUIT I changed C4 to 22nF and R3 to 33K. I didn’t scrap R2 (when I did, it fried the pot at some point), but changed it with a 47K, and replaced the pot with a 50K one. Then it was running pretty smoothly. WHEN SIMULATING WITH A SOFTWARE

You can use the 100uH inductors in series, they are there to filter out spikes on the mains, with the caps C1,C2

or try a 100uH inductor with 220nF caps C1,C2

I think Dodgydave meant to type "You can use the 100uH inductors in series..." Make sure they are rated for the expected peak currents.

The inductor is not important to the circuits operation; it is there to reduce interference to TVs and radios.
