Baldor motor Wye or Delta?

Hi,

I'm looking at this Baldor motor:
Here's the PDF:

Looking at the product PDF (on the last page) I can't figure out whether it's a Wye or Delta connected motor in the low (220) voltage configuration. I know the drawing is Wye but does that mean it's Wye connected in all the various configurations?

Sorry if it's a stupid question but I'm learning! Any advice is greatly appreciated.

EDIT: Baldor site down right now, here's nameplate and wiring diagram:

since nobody replied, i will ask
why does that matter to you?
you have the connection diagram, just follow it and wire it up
it will perform no matter which it is
in other words Y or D is of very little importance

Thanks for your reply. I was thinking of using it as a phase converter idler motor. I specifically want a Y motor for that (whether or not that's significant is a different matter, there is a few opinions on it). At the end of the data sheet there is this page: https://www.baldor.com/api/products/M3218T-50/drawings/CD0044

It shows the 3 different connections and their types which I missed at first glance. I wanted Y on the low voltage. This is parallel delta and series delta on the lowest and highest voltages, and Y in the middle one.

if you want Y because of amp draw considerations, i doubt you will find enough difference to worry about
the rpc's primary job is to generate the wild leg voltage, and #2 is supply 3 phase angle separation
amps is a function of load on the work motor
i have not read any threads here that convince me of an appreciable difference, and i have read most of the threads

i am also fully aware of the differences of amps per winding (which is different than per phase) between Y and D in normal use
but if you compare full load amps of the same HP, there is usually very little difference of FLA between them
sometimes the Y or D is simply the result of the most economical way to build a multi voltage motor
and it may not be common to find what you want

moving further into your planning
a 5 HP idler may not properly supply any more than a 3 HP load
regardless of winding or voltage or amps

Yes, 5 hp is a modest size for an idler, but I don't need to power much. I'm also looking at 10+ hp motors too, so its not set in stone.
I'm in the UK and need 400V 3 phase to power the typical 3 phase machine, many machine motors are 400V delta only, not dual voltage. I have access to a 8kVA single phase 230:400 transformer, as well as a 10 kVA 3 phase 230:400 autotransformer. Planning on getting a 230/400 delta/wye dual voltage idler, which would let me supply it either 230 or 400V single phase, stepping up the voltage before or after the idler with the right transformer. Still to be decided.
