How does a brushless motor beep?
« on: July 18, 2008, 12:44:45 AM »
I got a question on my mind which I can't seem to figure out. How does a brushless motor beep? I mean it is not a speaker or anything and yet it can make beeping sounds. How does this work? All a motor has is some wires and magnets but no diaphram so where does the sound come from?

Also notice how it can produce different volumes of sound as well? Also... some brushless motors are louder than others!
