I have a SHIZUOKA NC mill (converting it to CNC) and
don't know what the motor rating is. The nameplate is
on there. I'll have to recheck. Question is I'd like
to get 1 VFD for 2 different machines, is that
possible? How do I properly size the VFD for the Mill?
Where in the Rutland catalog can I find this and what
else is the VFD called?
Would it be better to make a motor mounting plate and
install a 230 1 phase motor?
Thank You,

Without knowing the motor ratings it would be hard to give you any detailed
help. However, you will size the VFD based on the total horsepower required
keeping in mind that sometimes when you are starting only one of the motors you
might experience some glitches as VFDs tend to like being sized close to the
motor specs it is running.

Another name for VFD is Inverter. You may find them called that in some
supplier's catalogs.
