Vibration motors are motors which deliberately generate vibration. These motors are used in mobile phones to create vibration alerting the user to a call or a message.
These motors are constructed just like normal motors. However, they have a mechanically unbalanced weights attached to the output shaft. These unbalanced weights create vibration. The frequency and the magnitude of the vibration can be changed by modifying the shape and weight of the counterweights.
