Not exactly useful for every team because it requires a lathe but... we had an interesting solution.
We clamped down our CIM motor inside the lathe and then, instead of turning the lathe itself, we powered the motor directly from a battery. Lathes are not designed to be used on a shaft that's spinning quite that fast so it generated a lot of heat (make sure to oil it up). In the end it worked perfectly with the small caveat that the CIM shaft had burn marks on it.
