AC Motor Speed Controller | Motor Speed Control | Motor

The speed of any AC motor is dependent on the applied frequency. However, some AC motors are just not suitable for variable speed operation. ... Smaller still, standard low-voltage variable frequency drives can now control permanent magnet synchronous motors in addition to induction motors.

For a Triac, the power pins are not A & K, anode & cathode but MT1 & MT2, Main Terminal 1 & Main Terminal 2. This is because the Triac is an AC current compatible device and in AC there is no seperate Positive or Negative.

Hallo sir..what a number for DIAC?or can use any number of part?

[basavaprabhush]

can i use 2 axial flux motors with one controller with ratings above than both combined??

[whatvideo]

I have made this circuit but at low speed the motor makes too much noise

[priyanthakjayalathge]

brother did you have practical knowledge and experience about this circuit? if it is why you not mention about Wattage potentiometer and load capacity?

[HWWoodard]

Thanks. When controlling a single-phase 120 VAC motor, will this circuit attempt to maintain speed when the load increases and slows the motor?

[deepikaraja]

Sir, i have tried this cirucit.After 2 hours of on, the resister and POT got busted.I was using 2.2K resistor 1/4 watt & 1 watt.Can you please share some solution to this.

[lyudmilvarbanov]

Hi,
I have an electronic board to control an AC motor -2500 watts/220v.
On the board are mounted two TRIAC - BTB24-600BW . The motor has a problem-runing on reverse only-no matter which button is pressed-FW or RW.
I found that the resistor who is connected to the Gate terminal on TRIAC 1 is burned and I replaced with a new one 47 Ohm/1 w .
Also I found a short cut between the Gate and Terminal 2 (the midle terminal) on the same TRIAC and replace it with new TRIAC--BTB24-600BW.After that I did a check by multimeter between all soldering points.
Then the board was connected to the motor.Unfortunatly the motor not run-in any directions- clock wise or reverse !
Do You can to gave me any advice?

[dadtechmech]

Always watching your tutorial cool presentation of your hideo

Can I use this circuit for 50w 220v .75 amps universal motor

[alchemy]

How many amps and volts can go through this regulator?
Thanks.

[nevereverlistens]

What amp and voltage rating is this schematic for?

[lightexposure]

Can i use this for 1, 300 watt vacuum motor?

[beecy]

Can u draw a wiring diag of speed controller fr an ac motor of 1000 thk

[horace]

Hi sir is it possible 3450 rpm reduce to 1720 rpm on motor

[myjames]

Hi there, can I use this to slow down a turntable running at 220volts. I need to run from 33 1/3 to 16 rpm.

[marktatis]

can a professional here tell me a version for an 11amp porter C 690lr motor and another for a 15amp hitachi c7sb2 motor, both of these are electrical tools

[roshnivalder]

AC supply is not L = Positive & N =Negative it's Live and Neutral !

[UNHAPPYMEXICANS]

Really feel like playing black ops 2 all of a sudden.

[MrGoddo]

Is anyone a somewhat capable DC motor "master"
I have questions :)

I have a fan that i have intergrated and infered 4x channel switch onto, to controle the speed using a remote, i want a stepper/DC-motor to control direction of it, but i have no experirence in how.

Im an electrician from denmark, and want to be better at low-voltage electrical"engineering" - if you have the now-how, id like to hear from you.
Im on discord
Kind regards
