I have moved to a new workshop which unfortunately doesn’t have a 3 phase power supply. So I am stuck with 240v single phase at the moment.
I have a 3 phase planer thicknesser, Mortiser and dust extractor which I’m not too concerned about as they all run from a 5hp static phase convertor that I have.
But I am having problems finding a solution for the CNC machine.
I am waiting for a price to put in a 3 phase supply, but I’m expecting it to be prohibitively expensive.
The spindle fitted is 4.5kw 380v 400hz 24,000rpm. (Can this be fun on 240v 3 phase with reduced torque?)
The VFD fitted is 380-480v 3 phase input, 0-380v 3 phase output. 5.5kw (can this run from a phase convertor?)
The options I can think of at the moment are:
Get proper 3 phase installed
Build a rotary convertor (maybe using my static and a large motor?)
Replace the vfd with a 240v in 380v out (I’ve seen one of these but it seems too cheap!)
Replace the vfd with 240 in 240 out and run the spindle on 240v
Replace both vfd and spindle.
Does anyone have any suggestions or pointers?
Thanks for taking the time to read!
