It works well and these motors are completely closed. So: No sparks etc. They are made for continuous action. But only if you cool them down. In cars the airstream cools it. For a ball mill two cheap 80mm fans do the job.
So i think, they?re really worth to experiment with. I supply them with an old AT power supply....
I used one to rotate my star rolling bowl, too. You can look at it here (Not finishes yet.)
