  Quote  I cant find anything on the required speed for this motor arrangement.


There is no simple single answer to that. But its not that fast.

Basically the faster you turn it, the higher the voltage, and because it uses permanent magnets, voltage goes up proportionally with rpm.

But there are many different ways of connecting the multiple windings to produce different output voltages and currents. To further confuse things, different model motors (over the years) have had different numbers of turns on each pole.

Best way is probably to mount it in a drill press or a lathe, and see what you actually have, with some real world testing.

Work out the rpm at which you eventually plan to drive it, then wire up the various poles to get as close as possible to your planned dc system voltage.
