belt sander conveyer control
 

I have a 24 volt dc motor that I plan on using for a conveyer on a
drum sander that I am building. My question is can I use a speed
controller for a router. They say it is for ac/dc

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.
