I recently purchased an older mill and lathe for my home and hooked up a new rotary phase converter to allow for 220V 3 phase power supply. The mill appears to run fine. However, when I power the lathe it turns slowly for about 15 seconds and looses power. I checked the control box and there are two componants (I forget what they're called) that get hot and cut of power. Once they cool I retry with the same result.Trying to troubleshoot, I first checked continuity in the windings to make sure I had rewired the motor correctly from 480V to
240V and that checked out according to directions I found here on this group. The next thing I checked was voltage at the 3 phase breaker. I got 110V from L1 and L2 coming from my single phase panel, but I measured 240V at L3 coming out of the rotary phase converter. That seemed odd to me but I am not very familiar with 3 phase power. I had assumed that 3 phase is 3 equal 110V lines. I will appreciate advise from anyone who might suggest what my problem is, hopefully my motor isn't shot. The motor is a 3HP Reuland and is "Y" wound.Thank You
