Re: rod-mill project - "mains" electric motor advice

Hi everyone
I have been shown how to do this with power-electronics and
"off-the-shelf" gearbox, etc.  With all speed-control needed.
A friend had made a small welding positioner.  Hence adapted it:
* VFD - 1ph-to-3ph
   v
* 3ph induction motor
   v
* worm-drive gearbox
You turn a knob setting the output Hz.  Adequate speed range.

Having seen this - that it works and does everything wanted - will
simply do it this way.
Have friend's equipment on "unspecified loan' in my car to take home and
play with more.
