There seems to be differences of opinion on whether a router motor will overheat when enclosed in a dust collection box. Some people advocate ventilating the dust collection box so that the router motor brings in outside air that does not come in around the bit. My engineering engineering intuition says the dust collector brings in a lot more air than the router motor cooling fan. I have conducted an experiment to explore this issue and the results are attached. Let me know what you think.
