John: No. Some might get so warm that it is UNCOMFORTABLE to hold your
fingers on the motor-body for more than a few seconds, but just a "touch"?
Seems, for it to be THAT hot, the PAINT would discolor! And THAT would be
TOO hot for the motor to last!

I have seen ratings of "105°C". That's a little hotter than boiling water,
and something dry (motor) could be "TOUCHED" without harm, so long as you
didn't HOLD your pinkies there for more than a couple seconds. But that is a
"RATING", not necessarily how hot the motor should actually GET in use.

Hope this little bit of palaver is of use! Jan Rowland, Old Troll
