My team did this in 2004. We used the drill motors which did tend to get hot.
We had two big aluminum blocks that were both mounts and heat sinks. Each piece had half of a circle on one side, and then screwed together to make a whole circle that the motor would go into. We used some thermal paste next to the motor and where those blocks attached to our main frame. That part of our frame was fairly heavy stock so that helped transfer even more heat.
