I think I mentioned this has a terminal voltage of around 60vdc, IIRC.
I found this out by empirical test.
The KB should run it OK, but you will have to restrict it from max output, put a resistor in series with the pot or method used to control the speed in order it does not over speed on full 90vdc, I would not run it over 2500~3000 rpm to be on the safe side.
Unfortunately I believe the plate info is OEM part numbers which makes it difficult to pin down exact specs.
