Cool! You do not need any Transformers (unless your AC system is a 4 wire Wye system and the Motor needs exact voltage).

Connect the Motor leads for the lower rated Voltage (220 VAC), and drive the Motor directly from your 3Ø System.

Must be a 50 Hz 4 pole Motor, judging from the 1410 RPMs! On 60Hz, this Motor will run at 1725 RPMs @ Full Load output.

Like that Power Factor of 77%!

The FLA figure of 6.9 Amps is what the Motor would draw at 220 VAC-50Hz, when 1.5 KW is drawn from the supply (and the output HP = 2 HP).

My power source measures 220 volts phase-to-phase and 127 volts phase-to-neutral.

No problem! The grounded Neutral Conductor is not used here - only the 3 Ungrounded Conductors (ØA, ØB and ØC).

Before I go any farther, are you reading 220 VAC on a DVM? Are you sure this system is 220 VAC and is 3Ø?

If so, you would find the following readings between Line and Ground (or Neutral):

ØA to Ground / Neutral: 120 VAC (+/- 5%),

ØB to Ground / Neutral: 208 VAC (+/- 5%),

ØC to Ground / Neutral: 120 VAC (+/- 5%),

If all three are 120 VAC to ground, you have a 4 wire Wye - with 208 VAC across the Ungrounded Conductors (ØA-ØB=208 VAC, ØB-ØC=208 VAC, ØA-ØC=208 VAC). In this case, you may want to boost the voltage up another 12 VAC, via an Open Delta booster configuration of two 250 VA Transformers.

If you only have 1Ø 3W service, you are out of luck!
