My son and I made this version of your desing. We powered it with a steam engine (air powered), also found on Thinkercad. We produced over 300 volts at full speed. A little bit to much for a simple school project ;-)
We did 650 windings because 800 did not fit in the housing. We also designed new endcaps to make it possible to mound it on a board.

Thanks for the models and information.
