I was finally able to track down a three phase transformer that was near me. This will allow me to convert three phase 240V to three phase 480 volt required by the mill and lathe. Though I only need a 6KVA transformer this one is 11KVA. Usually bigger is better, but if I get too large of a transformer it will pop the breaker. I should be ok with this one though.
It’s used but still checks out well with an ohm meter to check continuity. I’m not able to test it yet since I haven’t made a rotary converter yet. That will be happening soon. Here it is. It even comes with a “this can kill you” sticker.
This is what’s inside. Basically, it’s three iron bars wrapped in wire.
One step closer to getting the mill going!
