What does a vibration motor do?

 A vibration motor is an electronic device that produces vibration or oscillation for use in

a variety of applications, such as in cell phones, game controllers, and other electronic

devices. The vibration motor contains an offset weight that rotates rapidly, causing the

motor to shake. When a voltage is applied to the motor, the offset weight begins to spin,

generating the vibration. The size and strength of the vibration can be adjusted by

varying the speed of the motor or the weight of the spinning weight. The motor is often

used as an alert mechanism, providing tactile feedback to the user when a notification or

alert is received.

Above is mainly introduce of ERM vibration motor.

In fact,there is other type vibration motor in quick feedback.

Principle of Mini Vibration Motor

Principle of Mini Vibration Motor

After the DC current passes through the brush, current flows into the coil through the sliding contact between the brush and the commutator segments. 

The energized coils of different Rao groups cut the magnetic lines of force in the permanent magnetic field formed by the stator magnets, thereby generating electromagnetic force. 

The torque generated by this electromagnetic force causes the rotor to rotate, and the current commutation of the brush causes this process to cycle to achieve permanent motion of the rotor. 

The rotor drives the eccentric rotor of the mass to rotate, and the vibration motor has the effect of vibration. The vibration of the motor is mainly achieved by the eccentric vibrator.
