10 HP phase converter req'd
Ben,
Your 7.5 HP Interact CNC will need a minimum of a 10 HP PH converter to operate correctly. Bigger if you can afford it.

Phase converter running but low voltage
I finally got the phase converter running using a drill to get it up to speed, however I still don't quite understand some things. I hook up 110 to one lead and the other 110 to the second lead. these are not marked so I'm guessing. the third lead I assume is the ground even thought when I measure across these leads none of them show a connection to the motor housing. If I hook up the ground I get a humming noise and it goes away when disconnected. the converter runs on its own when I get it up to speed but the voltages coming off the lead 111,112&113 are very low, about 23.5 volts. what am I doing wrong???????
I was told by the previous owner that this 5HP converter would run the mill, which uswes DC to power the 7.5 HP spindle motor.
Help me PLEASE
Ben
Still confused???????????
Which leads do I use to hook up the 220v? I have 6 leads, three marked 111,112 & 113. then three other leads not marked. some diaigrams I've seen show hooking the 220 up to leads 1 & 2, which I assume are the 111 & 112.
