Centroid Community CNC Support Forum

I have a 1998 Atrump bed mill M40 control. Me problem is I’ll have no 3PH at a new location,is there a phase converter that will work on that mill?

You can use a rotary phase converter to generate 3ph for the entire mill, or you can add individual VFD drives for each of the 3ph motors on the machine, and power the mill with single phase 220V. The Centroid control itself uses single phase power. If the spindle is the only 3ph motor on the machine, you probably have everything you need already, just verify that the existing spindle VFD is rated for single phase input. If not, that will need to be replaced.

The spindal motor is six hp I’m looking at a 20 hp PH converter......

I will need some power for the other machines in the shop....

i used to run several machines at the same time on a 7.5hp 3ph home brew converter.
