The machine will be single phase with a VFD for the spindle.

I just found out the coolant pump is three phase. It is 1/10 or 1/20 hp.
Using a clamp type ampmeter it just tickles the needle on the 6 amp full
scale setting. I'll guess .1 to .2 amp per phase.

So, would it work to just use a run cap accross L1 L2 L2=wild legto start
this thing? How large should I try?

If needed, I could use a start delay timer and bring in a cap accross L2 L3.
Need this? How large?
