Variable speed motor for my 110V mill/drill?
 

Wondering if anyone has any suggestions for putting a variable speed
motor controller on my little 110V mill/drill. The belts are a *******
to adjust for different speeds... it would sure be nice to just turn a
dial and still get reasonably good torque w/ a reasonable amount of
speed variablility. And, I'm doing a CNC conversion soon, so this would
really be a + (especially if it has an an analog input for adjusting
speed).

I've seen a lot of Variable Frequency Drivess on ebay for 3ph stuff...
wish I had a big mill with that kind of motor... but my mill/drill will
have to do for now.

What about 110V 1ph? What kind of motor controller and who are good
sources? Is this even a good idea?

I have a Smith mill/lathe that I have a 1/2 hp D.C. motor and controler and
it works real well. I got the motor and controler from a place in Cestline,
Ohio http://stores.ebay.com/id=11818209&s...TRK:MEFS:MESST
http://cgi.ebay.com/ws/eBayISAPI.dll...2179 049&rd=1

They don't have a motor listed on ebay, but they do have a controler list
for $25.00. I was at there location Saturday and I think they had a couple
1/2 hp motors. They are a recycler so stock comes and goes. I think there
phone number is 419-683-3535. I have gotten a lot of stuff from them, both
from ebay and at there location.

I been researching the same thing for a benchtop lathe and have found a
few googling and a few in the yahoo groups for the 9x20 lathe group and
some in the lathemaster group.

They use lesson treadmill dc motor (2 hp inverter type) with a Hatachi
vfd type controler. I don't have the links handy, sorry

I recently bought a junk Atlas lathe that had a 2 HP DC motor and a big
variable speed controller attached to the side of the bench.
I have seen similar items go on ebay recently for about $150, sometimes
less.

Noise! Power = noise. Look at any carbon conmutator motor such as on your
3/8 drill or shop vac or sewing machine motors. But since you will be
converting to NC, you should include servo control and a servo motor which
will give you nice, quiet, power under full load or not.

If you switch to a DC motor, I have a suitable Minarik controllers for $35
to $55
