Since the inner racer is free to turn around the axle, I have a hunch that what matters more is the shape of the balls rather than the rolling motion of the balls. If you jammed the balls so they couldn't roll I conjecture your bb-motor will still want to rotate when you apply the juice. I am assuming the fit between the inner racer and the axle is sufficiently snug and frictionless for this to work. Harry
