I have a Rotary Phase Convertor (made by an electrical repair shop) that came along with the CNC machine (10HP) I bought used. I contacted the convertor builder and he said not to run any other machines on the convertor when running the CNC as it was balanced for that one machine.
I have seen in supply catalogues that factory built CNC convertors appear to be built at what appears to be double the capacity that would be necessary for manual mills. I plan on getting a 2nd CNC (10 HP) and I am looking for any suggestions as to the brand, size, and any additional tips, before getting another phase convertor to run it.
Thank you.
