It would be fun to try a water-cooled can using a helically milled slot and a sleeve.............
We can run a thread program for the fins. Of course, we can also just turn the center portion of the can down with no fins, then run a sleeve around that. RC boats use a sleeve just like that.
Thing is, I highly doubt heat will be an issue at all. But, we may be able to get 30kw out of this crazy motor IF it were liquid cooled. You never know.
Actually, back 10 years ago, I was liquid cooling car audio amplifiers. So, I am very familiar with small scale water pumps, small radiators, and related equipment as well as air bubble purging from these systems. Of course, now we have PC liquid cooling systems. It would not be difficult to hybrid one of those to cool a motor.
Again, I doubt heat will be a problem.
