Hand Held Electric Vibrator

Historically, mechanical vibrators got their name as a result of the metal armature that vibrates in proximity to a kind of an electro-magnet to open and help close the focuses. The hum that you hear when your radio is operating is a direct result of this action.All vibrators have the same working principle. An electric motor with an unbalance mounted on a rotor which generates a circular vibration with high centrifugal force. The centrifugal force depends on the unbalance and rotor rotation speed.
