4 hours -- no real problems

The motors stopped getting hotter after about 20 minutes (based on my calibrated hand ;-).

After that, the motor just ran and ran.

After 4 hours I stopped the test and took the motor apart again.

Nothing changed really on the inside other than it was clear that the oil impregnated bearing dripped a bit of its oil down the inside of the end cap.

I suppose that everything will be just fine with these bad boys.

P.S. In another note, someone asked in a separate note whether it was safe to press something onto the motor shaft. I think so. The shaft is a 8mm shaft all the way through the motor. The back of the shaft is held against the inside wall of the casting. I think as long a you don't go crazy with a very tight press fit you should be fine. But... ...as always, your mileage may vary.
