Hmm, sounds like you are running a 24v sepex at 72v, most sepex come out of forks and most antique sepex do indeed run straight off the pack voltage, of coarse if you up the ante it will not like more for long.

Of coarse modern sepex use PWM on both field and armature so you can similate different torque and rpm levels.
