Is the machine with the 10-15hp running a 3ph motor straight off the line or does it have a Spindle controller?
If the former, then You might get away with a VFD set for 60hz only, with slow ramp up.
You may be restricted to operating in lighter duty.
That is if the VFD does not require or monitor the 3rd phase.
The alternative is a RPC, especially if the machine has a spindle controller.
