Bang on it with a hammer

We have all experienced the old stuck starter motor. Often smacking it a couple times with a hammer seems to fix it right up... for a while. What is the cause of this problem so often fixable with a hammer? I'm guessing a stuck brush and maybe a wore out brush approaching the end of its life so it can more easily cock in its channel.
