Default quick question on the outrunner/inrunner thing

So, I have a 450XL motor. when the pinion turns, the outer case does not.
Is there an inner case with the magnets which rotates around fixed stators?

I thought that the outer case of an outrunner would spin, scary though that may be, and it thereby provided a cooling benefit.

Wrong again?

thx
Jim
