Variable Speed Regulator for 24-VDC Motor from 120-VAC

Look for a servo amplifier such as Copley or Galil.

Thanks Bill.

I visited both sites and poked around some. My concern is that the cost of those you suggested will exceed my budget by a substantial margin ($100.oo)

I'll call both of them tomorrow and ask some quiestions.

I spnt some time with the nice folks at KB today. Came close but no cigar.

I suspect that, like it or not, I may have to solder up an oscilator type PS like those I saw last year. All of them kits!

Thanks again

Item #'s 140300958034, 260291275497, 350165312924 on eBay less than $100 (like $40)

There's others too.

It was very thoughtful of you to go looking for me. I appreciate your doing that.

I checked out all three items. Unfortunately, they are DC to DC units. I need 120VAC to 24 VDC and it must be variable.

Still the search at eBay was fruitful and promises to help locate what I need.

Thanks Bill!

But adding a few diodes and a cap or two and the problem is solved....

a auto-regulator, a rectifier can do the trick.

Auto-regulator as in auto-transformer, such as a VARIAC^tm?

That's a fairly inexpensive way to do it, but there's no feedback, so as long as load is constant, the speed will stay fairly constant.

yes, no feedback, but someone neednt it. he need only veriable speed set in lower charge. but if he would need it to get a stable running, need add more 20--30usd to get it within 5-30ms respond time.

but still less money compare with all solid devices regulator. of cause not too much accuracy.

100usd , I can offer him some.

". . . . of cause not too much accuracy."

I do not need super accuracy, so long as the speed is reasonably constant.

As soon as I changed my search to "DC motor speed control", prices started to drop considerably from those quoted earlier which were all regulated supplies.

The problem is that most of those in the voltage and amperage output range I want were pumped by a DC source. That means an additional rectifier supply. I want something that is fully integrated.

Google has turned up some interesting ideas. I am also going to call a supplier I've worked with before who sold me single to three phases 220 volt motor controllers. He may have something suitable in DC.
