some more follow up info - the pump on this mill is .15 amps at 220 -
no need for fancy circuitry there, though we shall see - the motor
that moves the ways is 5.9 amps, (2 hp) the spindle motor is 6 hp,
so, any thoughts?

this Abene mill finally arrived - a long story. The good news is that
it's wired for 220, so I won't need to worry about a transformer or
other means to convert to 440 - everything seems to be dual voltage.
My plan, unless someone here has a much better idea is to use two
VFDs, one for the spindle motor, one for the ways motor, and to use a
suitably sized capacitor for the coolant pump - a little motor that
doesn't seem worth a VFD of its own. I like the VFD approach because
of the soft start. If anyone has a better suggestion, chime in.... I
don't really want to use a rotary converter because of space
considerations

so, after wanting a milling machine for a few years, I broke down and bought
one - this one

to be specific. I've mailed $$ to the manufacturer in Sweeden who will send
me the manual (cheap, 55 euros), so now while I'm waiting for delivery, I'm
turning my attention to the next problem - how to power it.

You will notice that it says it's 440V - I don't know if the motors, etc are
dual voltage or not, but my garage doesn't have 440 in it. Of course I can
use a transformer and a bunch of VFDs or a rotary phase converter, or ....
but I wonder what the group experience might be. I can also rewind the
motor for 220 and use an off the shelf VFD, or I can modify a 440V VFD so it
accepts a DC input and then make a DC power supply (e.g. full wave doubler)
to supply it from the 220, or .......

so, what do you think?
