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.

What makes a cellphone vibrate?
Among the many components inside the phone is a small motor.
The motor is built in such a way that it is partially off-balanced.
In other words, a mass of improper weight distribution is attached to the motor's shaft/axis. So when the motor rotates, the irregular weight causes the phone to vibrate.
I saw a part of my Motorola Moto E's motor when i opened the back cover.
Below is the image of one type of vibration motor; there are many types.
The size is small... smaller than many currency coins.(More motor info can refer to :www.vibrationmotor.net)
The mass at the left end, almost resembling a half-moon is the off-balanced weight, the cylindrical part contains the motor.
Hope this helps. :)
As I mentioned earlier, there are other kinds of vibration mechanisms to0.
Here is also a link for the vibrating motor in action.
TIP :
If you want to turn vibrations off in order to save battery, you cannot do it all at once. You can turn it ON/OFF for Messages or Calls by going into the Main Settings.
But notifications for individual apps like Whatsapp, Hike, Facebook, Yahoo Mail, etc. need to be handled from the respective settings of each app.
By going through the settings of individual apps, you may choose -
- vibrations or led notifications for alerts.
