Could be the inrush when the contactor closes it's too much for the Fan motor, what is the amp rating voltage of the fan.

220V
60Hz
0.49A
160W
1450R/Min

The challenging thing is thats it's working fine today.... so it's hard to diagnose a piece of equipment when its currently working.

I bounced my issue by the company that I purchased my solid state phase converter from and he suggested a 3-phase 240v > 228v buck boost transformer of at least 15kVA.

So I ordered one up and we will see if that fixes the issue.

I've been running the air compressor all day today with my CNC and so far it's only alarmed 1 time. ( however it hasn't needed to run the fan motor yet because it cools down quick enough in between cycles )

I do have to say that I am very, very happy with the nice quiet operation.... It's a joy to work next to the CNC now without that loud compressor clanking away.

I will keep you posted once I install that transformer.

Take Care...

The transformer will lower the voltage, which should help, but may not solve the problem.

Such a small motor like this should not be turned on / off with a contactor, they should be using a solid-state relay, so this is where the problem is, not with your power supply.
