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. JIm Geib Mansfield, Ohio "stag" wrote in message oups.com...

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 Jack |

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. - - Rex Burkheimer WM Automotive Fort Worth TX jackK wrote: stag wrote: Wondering if anyone has any suggestions for putting a variable speed motor controller on my little 110V mill/drill.

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. Wayne |
