No. It's a Baldor motor. Two voltage capability. But nothing about
different speeds.

The dual voltage capability will be the reason for the two identical
main windings. They will be connected in parallel for 115 V operation or
in series for 230 V operation. They aren't intended for speed control. I
think the only way you can vary the speed of this motor is to change the
supply frequency.

And not very much, with a single phase cap start motor -- unless
you are willing to switch the start capacitor value each time you change
the frequency.

Enjoy,
