Currently wiring up a shop, thought I had 3-phase accessibility, but the Electric Co now says nix, add $6K for 3-Phase- deal breaker for me....
Power/Machines: (All already wired 3PH)- 1- 5HP Lathe, 1- 2HP Bridgeport, 1- 2hp 3Ph grinder. Use is light, more hobby level, retired several years ago and now just playing- I just need Lathe and Mill running to make 'stuff' as desired... Once you get use to have the access, it is hard to get along without it!
Electrician says history is in favor of a quality Rotary Phase Converter, CNC qualified being the best. He does not have a lot of experience with a VFD (Variable Freq Drive) but notes they are 1/3 - 1/2 the cost of the Rotary Phase converter. He goes on to honestly state there are solid circuit drives and hybrids that he has no experience with.
What would your choice be and why?
Thanks in advance for your time and consideration in responding.
