Which motor is used in mobile vibration?
What Is Mobile Phone Vibration Motor. There are two basic types of vibration motor. An eccentric rotating mass vibration motor (ERM) uses a small unbalanced mass (we usually call it eccentric weight) on a DC motor, when it turns it creates a centrifugal force that translates to vibrations.
How do vibrating motors work?
An eccentric rotating mass vibration motor (ERM) uses a small unbalanced mass on a DC motor when it rotates it creates a force that translates to vibrations. A linear resonant actuator (LRA) contains a small internal mass attached to a spring, which creates a force when driven.
What vibrates in a phone?
Now, all modern smart phones and phones are equipped with a vibration motor. It is a small electric motor, on the axis of which a metal cylinder is mounted. When a call is received, the motor starts to work and rapidly unwinds the cylinder. Vibrations are transmitted to the phone’s case and it starts to vibrate.

What causes a motor to vibrate?
The main causes of motor vibration include, but are not limited to an electronic or mechanical imbalance, faulty gears, failed bearings, loose foundations, wear and tear or misalignment. Imbalances: An imbalance is like a weighted spot in the rotating component of a motor.
What is vibration motor in Arduino?
Vibration motor is a DC motor in a compact size that is used to inform the users by vibrating on receiving signals. It has no sound. Mainly they are used in mobile phones, joysticks, pager and so on.
