i don't remember but it's a pretty powerful motor, so probably as many as you
want.  it's a heavy-duty assembly, the hollow shaft to the vacuum plate has its
own pair of bearings supporting it, independant of the motor itself.  So i
think the vacuum grip to your board (and properly centering it on the center of
mass) is your limiting factor in spinning it fast.
