I have a 240V 30hp rated Desco phase converter with a 30hp Baldor Motor. I have been using it for probably 10 years to run the 15hp motor in My Monarch lathe and have not had any issues. When i installed it I checked voltages and they were like 244, 246,244 and I thought that was great. I recently got a mill that supposedly has a 20hp motor in it. The mill has hydraulic pumps so it doesn't start the motor with no load like on my lathe where the motor is declutched. The mill starts and runs, but upon startup it gives the idler motor fits, it starts buzzing and jumping around in the floor for about 5 seconds until the mill comes up to speed then it is fine. When it is running and I check the voltages they are still well balanced. I tried starting the lathe first to add its 15hp motor into the mix but it didn't seem to help any. Do I need to add more caps for starting? Would that help? Can I add to many starting caps? I need to get someone to help me so I can see the voltages on the phases at startup as of now I can't hit the start button and be close enough to see the voltages on the meter as it is on the other side of the mill from the start button.
