Re: Heat Sinks for Drill motors
the drill motors have a pretty powerfull blower built into it - as long as you dont block it, it should cool itself ok
if the motor IS heating up to where you need a heatsink you need to lower your gear ratio
the windings are on the armature inside the motor -thats where all the current flows - the outside is only the magnets
if your motor is getting too hot, putting a heat sink on the magnet shell wont help the armature any, and thats where the wires are that will cook on you.
