| Is R13 not 0.47Ohm?
I mean on full steam the written 250W motor consumes more than one amper, counting that through with this 1ampere
U=I*R=1*47=47Volt , P=U*I=47*1=47Watt ????!!!

| wonderful circuit.
is it feasible to use this circuit for 220V? |

| I suppose number of turns for T1 transformer should be half for 220V. Pls correct me if I'm wrong.
I trying to build for 220V... |

| dear sir,i have an ac induction motor drive and also have a input circuit (i use previousely to operate a dc motor),but the problem is it not works on ac drive.can u suggest on it.
i can provide technical detail and pictures of entire system.
waiting for ur early reply. |

| About the diac used in the speed controller( to the person looking for a match to the triac) Diacs are not much different depending on the part # they only severe to allow the triac to trigger symetrically in both polarities of gate signal. They will not pass current until the gate trigger signal rises above the mid twenty volt range in either +/- voltage. |

| I was reffered to your site. I wanted to please ask if you could show me how to add the AC motor controller to a vacuum cleaner that is way to fast to clean floor rugs, blinds, and counter tops....
Please be sure that your help with this matter willl be very much appreciated for sure.
Willl be looking in the email for your reply.
Yours Respectfully, WC |

| hi sir i choosen this ac motorn speed controller as my project
details of this project is very less so please kindly send to a mail to me about all details and cost
and another my main doubt is ratings motor so please mentioned the ratings of motor |

| Great design! Took me about 2 hours to assemble and tweak. Works just as I wanted it to; took my studio exhaust fan down to a nice slow rotation - just enough to pull a gentle draft out of the room.

| Hey all, I just stumbled on this schematic, and headed off to eBay... I found a BTA12-600B (600V, 12A max) TRIAC 2-pack for $2.50 shipped... The only problem is I'm not finding any DIACS that are anywhere near my needs (120V, 300W motor), much less being anywhere close to matching the TRIACS as mentioned in the notes. Anyone have any suggestions? Thanks. |

| Some strange comments here. Love your circuit, much better than most triac circuits posted. I haven't tried it yet, but I will. Always looking for a better triac circuit to try. I'll let you know if it doesn't work. |

| a 3 phase motor is really just a large stepper motor, which uses the ac sinewave phases as it's timimg source. essentially to reverse a three phase motor , all you need to do is reverse two of the legs (phases) this can be done with a reversing motor contactor or a dpdt relay wired as an h-bridge.
BE VERY CAREFUL
3 phase industrial electricity can kill you,and I've come darn close! that may result if if you don't know what you are doing, you could have a real mess on your hands |

| i need the automatic circuit diagram for a three phase motor turning clockwise and counterclockwise by changing the order of phases.I need the circuit which has a timer and turns the motor CW for 5 minutes then stop for 1 minute and then again turns the motor CCW for 5 minutes. |
