Could you please give an an example of 1.732 single to 3 phase perhaps based on my 8.8 per phase 3.2kw motor

You mentioned Trick wiring. Can you explain

Also, does the attached chart look accurate?

thanks again

I don't think your 3.2Kw spindle will be 8.8 per phase

Trick wiring, well it is not for everyone, so I only post about it when it is needed. at this point you don't have a need.

Motor name plate Amps or FLA x 1.732= the required input Amps for Single Phase Supply to 3 Phase, plus 125% for cable and Breaker size, you can work it out from this PDF

What do you figure my spindle will draw per phase, under 8? Manufacturer says that 120% of rated for 8 sec is max recommended.

Unless I push it hard, I don't think I'll ever see much over 20 amps in the single phase side.

3.2 kw @240 v (my supply voltage

3.2/.24 X1.25 = 16.7 amps

Distance from service to VFD is under 6 feet

If the name plate amps are 8.8A then it should be around 3A per phase

It's as clear as mud.....lol

I'll get it eventually, I hope

thanks again, you are a wealth of knowledge
