belt sander conveyer control

Router runs at what voltage ? Your DC motor runs at 24v. That is my question. If the Router controller is 120V waveform output then no.

Spec the ac/dc - is that input or output of the controller ?

My suspect is it drives 120V AC or DC motors. Must be a square wave box.

No... but you may want to consider a motor/controller from a treadmill. It has a strong motor with a speed controller. Sometimes they can be had for free.

the router is a triac based control, it will control AC brushmotors just fine, but will not work with a DC input - this is beause it works by duty cycle modulating the input power and if there is no zero crossing the triac wont turn off. DC motor controllers are made by Minarik and other companies and are found used on Ebay and the like - but I suspect you will find it less expensive to buy a motor and a controller -that is unless your 24VDC motor is quite special.

^^^^^^^^^^^^^^^^^^^^^^ Bill, if you reread the original post, you will note that he does not propose running the DC motor on DC. Brush motors will run on AC, and he might be able to use a router control, provided he matches the voltages with a transformer. This could be tricky, though, because it depends on how the transformer reacts to the peculiar waveform output of the speed control. Putting the transformer ahead of the speed control could pose other problems with the triac--I just don't know. And then again, it might work just fine.

Tredmill motor controllers are 90v.

What is needed - maybe - is a golf cart or little 3 wheel old person scooter.

There are 24 volt controllers made for motors.

My point was to use the motor and controller. Not just the controller.

aaah, noted, but a DC PM motor will just vibrate, not rotate, if energized with AC, hence the presumption of DC

^^^^^^^^^^^^^^^^^^^^^ Yes, Bill. I realized that after I hit "Send." (About 1/2 day after.) So, if it happens to be a PM motor, what to do? How about running through the speed controller, then transformer, then rectifier?

that MIGHT work, but it seems that the OP was a bit light on electrical knowlege so it might be too complex - what I would do if I had that exact situation is either run Xformer, then SCR/Triac based control followed by a bridge rectifier, or make a rectifying controller by using 4 SCRs in a bridge configuraiton with a simple phase shift circuit - since I havea small pile of little variacs, I'd probably just go with the variac and see if the thing worked like I wanted. But for the OP, I think the suggestions to find a motor with the controller are best - there is some guy on ebay selling small motors with a controller for around $30 - don't remember who or the exact name of the product, but I do recall thinking it was a good price for a sewing machine type motor with controller.
