Setting stroke on Douglas Shaper

Shawn, you never run neutral to a motor unless its running on 110. Can't quite make out the voltages on the tag but it looks like the low voltage is 208, somehow you can get that voltage on one leg of 3 phase, (Im not a sparky) so for 220 or 230 volt depending on how you interpret it your power should come in on pins 1 and 3.
The speeds listed are for 50 and 60 Hz.

A better shot of the plate would be nice to make sure.
