Hello all! I just purchased a bridgeport interact 1 mk2 and I have it here sitting in my garage. I have some experience with CNC but this seemed like a good machine to own and have some fun with!
Anyway i am looking for a solution to connect the mill. Unfortunately i do not have access to 3 phase power where I am located so this is my first challenge.
I have dome some reading and it seems like american rotary makes one of the best rotary phase converters and priced well too. Their CNC phase converters allow no more than +- 5% voltage variance between the phases so it should work well for my application.
I have all the manuals with the machine and it calls for a 20 KVA power rating. Now this doesn't really make sense to me because it calls for a main breaker of 50 amps at 220v which gives about 10 KVA.
My main questions is what size of phase converter am I going to need. I will never get this thing to full load and I don't want to spend a huge amount of money on oversizing a phase converter that i will never take advantage of.
The machine is 9HP by what i'm told so I really don't see where the 20 KVA is going, but maybe someone can make a good suggestion for me?
The machine was previously wired for 575 and I will be keeping it that way since i already have a step-up transformer ready to go and I don't feel like setting the machine up for 220 if I already have the transformer.
Any info is greatly appreciated! I want to see this thing come alive so I can start working with it.
