I moved on to Solidworks design and CAM programming in another state and eventually got a job making high pressure valve components on multi-axis machines at SpaceX here in Los Angeles, where I am now.
I bought an Avid router for my home shop, and - because everything is gas in Los Angeles - unfortunately I only have access to regular domestic power. As an apartment dweller in Hollywood, I'm lucky to have a shop at all, so any discussion about 220V single phase is just not worth having. I am trying to figure out how to make this work with only a single 20A circuit. Okay, with that out of the way...
Can we agree that 230V/3PH is just three legs of 110V, 120 degrees out of phase of each other? IN THAT CONTEXT, how is 110V/3PH different? We can talk amps all day, and square roots of three and whatever you want. So far, pretty much everybody here has given half of an explanation for some reason and/or in run on sentences that go nowhere. Also, the explanations seem to be wrapped up in a message about not using a particular product that has nothing to do with my question.
Hey! Small world, it has been a while. Sounds like you are doing well. I have added a bit to my shop since you last saw it, have a Hardinge CNC lathe and a Haas TM-2P now. Both are making parts as I type this. Been a bit busy.
Not exactly, 230V 3 phase is 3 legs of 230V, 120 deg out of phase with each other. 230V 3 phase is kind of an oddball in North America today, at least as supplied by the power company, more common is 208/120V and 460/277V. I'm not going to go into a long explanation about why this is. ADX was wired for 230V 3 phase, but that was a very old power system.
Functionally, 110V, 3 phase is just like any other 3 phase voltage, no difference at all. Just not a good fit for 120V domestic power.
I would hang a Dewalt router motor (because Porter Cable stopped making the 7518 motors) on your machine and be done with the problem.
