I'm on the verge of buying a VMC with a 10HP, 8000 RPM spindle to put
in the garage.
Sadly, there is no 3ph power there.
Sooooo.... I was thinking of either building a rotary phase converter
(I already have a 20HP Baldor motor holding the floor down), or trying
to rig the machine (Advanced Mighty Comet VMC 520 with Mitsubishi
Meldas control) to try to run straight from single phase power.
Anybody ever wired their VMC to run straight from single phase?
If I could safely and reliably run the VMC straight from single phase,
that would be preferable to having a 20HP idler motor running, making
noise, drawing power, ...
The other thing about a 20HP motor is the startup/inrush current to
start the thing. I don't think I have wiring in the walls that is big
enough for the house I am renting).
Are there any soft starting rotary phase converter plans out there?
How do you accomplish soft start?
Anybody in the SF Bay Area have a 15HP or larger soft starting rotary
converter for sale?
Thanks in advance!
