The whitish blob on the back of the motor in one of your photos is a speed sensor. In the washing machine's controller which uses an IC controller this feedback is what enables it to run a steady splosh splosh splosh on the wash cycle. Worth using that if you can figure the wiring for the controller.
One I played with (Hotpoint I think) wired series wound field would turn over on just 12v and got up to over 10k rpm on 70v, no load. About 20+ years ago at the ME exhibition someone showed a 12ft submarine using 2 on 24v.

Hi
Trolling through my "That May Be Useful" files on a remote drive i found this that may be useful info on the high speed motor you have.

Hmmm! Unable to send Attachment PDF File. Send me a personal message
