AC motor speed controller via 5v PWM

Hello everyone, to start yes i know this post has been asked many times before but i hope to get a more up to date answer to the question and hopefully something i do not have to create myself.

I have been creating a environmental control system which i started as just a fun idea but now i have quite a few subscribers and as a result requests for more features, one of those being AC dual fan speed control to maintain the air temperature and humidity. The code is not an issue and in fact i worked on a AC fan speed controller at my last job though i did the GUI code but i have access to the fan logic which works perfectly.

My question is, is there a AC fan - motor controller which operates via a 5v PWM signal that i can just buy rather than having to create a custom PCB? Else if i must create it myself could anyone recommend a good example - tutorial on how to create one, I really dont want to have to create my own as it would take time and money but if i must then so be it.

I found a simple one already but from what i can tell it is not PWM controlled and rather just fixed output?

Sorry to rant on and i hope you can help me,

You may find something in this thread if you don't otherwise find a complete, ready made solution. It is about "retrofitting" a commercial, non-isolated AC mains motor controller with an Arduino controllable circuit using PWM over an opto-isolator.

There are several, if my memory serves me Alan Bradly made them. Most controllers I worked with were either a voltage input 0-5 or 10 or 0-10 ma current loop, You can find them with a google search, you also know the mains voltage and if three phase or not. You wall also need the motor ratings. I have worked on fans that have 480 3 phase power motors driving them. These we typically used VFD (Variable Frequency Drives). This response is to help you get started in solving your problem, not solve it for you.
Good Luck & Have Fun!

For AC control will usually use phase cutting and a TRIAC.

Not for an induction motor, that's only for universal motors.
