3 phase motor math

Hi guys,

I have a nice old 3 phase motor I want to hook up to my VFD. I've gone
through all the motions of opening it up and cleaning it a bit, and
checking the resistace between windings and ground, and it seems okay.
What I don't know however is whether it's wired right..

My VFD outputs 220V, so I'd need the motor to be in the Delta
configuration.
The motor has the following written on it:

Volts: 220/380-415
Amps: 3.45 / 2.0

I measured 25ohms between each connection point...
But the usual V=IR formulas totally don't yield me any answer.. it must
be because it's 3 phase and AC.

I Googled for 3 phase motor/resistance/amps formulas but only came up
with a lot of junk people were trying to sell me, and some other stuff.
How do I work out what voltage this motor is currently configured for?

Thanks!
-Abby
