What about putting heat sink fins on the motor case? Do you know
whether the problem lies in the heat transfer from the windings to the
case versus the case to the surrounding air?

How will a person judge when holes will lead to breakage?
any examples of people doing this already ?
Do you want the motor to be waterproof (rain, mud, ...) or not?
If you leave it open (with *many* holes) then it can cool better
but (like a DC motor) you better blow filtered/screened air through
it if
you want to avoid road debris, dirt, rain and stones to be eaten by
the
motor.
