Bridgeport motor question

I'm preparing a series1 (BOSS) Bridgeport to fit PC-based controls.
The main spindle motor is a US motors 2hp, & though the rating plate
gives a connection diagrams (9 wire) for 220 and 415 volts there are
actually just the 3 wires coming from the coils and I believe it was
set for high voltage. I want to run it from 240Volts via an invertor.
I'm going to see if I can unearth the actual winding terminations,
but
if I get too far out of my depth it'll be off to the rewind shop on
Monday for them to do it.
My question is, as understand it the US style 9-wire dual voltage
motor is star connected for both voltages. More usual here in the UK
is 6 wire, with star connection for high volts & delta for low. If it
looks easier to reconnect this motor for delta than to unearth all
the
terminations to parallel the windings, will that be just as good?

Many thanks
Tim
