Vibrating Motors
Vibrating Motor is essentially a motor that is improperly balanced. In other words, there is an off-centered weight attached to the motor's rotational shaft that causes the motor to wobble. The amount of wobble can be changed by the amount of weight that you attach, the weight's distance from the shaft, and the speed at which the motor spins.This type of motor can be used affixed to all kinds of objects, which will cause them to vibrate and move freely about. This is a quick and dirty way to get a simple bot to move about, but not exactly the most elegant. Vibrating motors can be found inside cell phones, pagers, gaming controllers, and personal massagers.
Working Principle
During rotation, the eccentric weights mounted on the two shaft ends generate a circular vibration, causing a vibrating motion to be impressed onto the components coupled to the motor base - such as trough conveyors or screening machines.Two counter-rotating vibrating motors generate directed vibrations.The vibrating motors are selected according to the required centrifugal force and the desired speed.
