One of my other hobbies (nitro RC Cars and trucks) uses this method.

you will notice that the "gear" in the picture has holes all the way around.
(Similar to a large technic gear)....friction pegs slip into these holes. This
gives you some amount of adjustability based on how many pegs you choose to use.

This is a very effective way of controlling slip. An RC car engine can easily spin up to 30000 rpms so dust from the pegs is quite apparent after some use. I doubt anyone will get a lego motor to spin that fast :) .....but I would still be concerned with dust.
The pictures I listed do not show the rest of the setup, which involves a shaft
through the center of the gear..a spring some large washers and a nut. The more
you tighten the nut...the less slip you get...
