I've asked Cedric Lynch to join in with this group, since he came up with
the motor construction in the first place. Hopefully he'll get around to it
soon.
The Perm motor is really the only motor you need to worry about locking up.
The Eteks, the original Lynch/Lemco, and the Agni, all have more or less
smooth outer casings. The Etek was redesigned that way, since it overheats
quite easily. It's only the Perm with it's peripheral cooling slots that
really seems to have a problem.
In any case if you keep the peak motor temperature down, you shouldn't have
a problem.
