Slowing down a clothes dryer

[Aussie Barry]

The drum of a clothes dryer is belt driven.
If you are looking for a slower, but fixed, rotational speed it might be easier to reduce the diameter of the pulley on the motor to achieve the desired result?

there is always something like this

there was an article in silicon chip mag years and years {ancient historical times when everything was not made in china} ago that described and designed the kit

Thanks folks.

I've since learned of a thing called a centrifugal clutch which is going to interfere with what I want.

Thanks for your advice. I'll must likely take out the motor, reduce the rotation using several pulleys, and use a much smaller "tub" for my use.

Can you weld? If yes you can add an idler pulley to slow the rotation. You'd still have to do the math as to what size pulleys you'll need but it could be done. I don't know if you'd be able to do it in one step because of the size of the pulleys.

Another option would be to find a suitable washer with a DC motor and refit into your dryer. Then you can worry about PWM. A treadmill motor would be perfect as the control is already done for you. Mounting may be a challenge but refer to first question.

If you were closer to Las Vegas, NV I could fix you up.

I thought of that, but buying pulleys, shafts, bearings and metal will quickly pass $50. Add the cost of that 4 prong 220V receptacle and I'm at $100 with taxes.

I thought of a washer motor. I have one on hand and they operate on 110V so no fancy power plug required. I'm pretty sure this will be the same AC design.

Most definitely, powerful and 110V, but don't have one.

I really would have liked that.


My primary goal was for this project to be dirt cheap. I can get a new case cleaner for under $100. It's not large capacity, but it would do for my needs.
