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.

How to choose vibration motor
How to choose motor vibration motor
There is 2 typical vibration motor:
1.cylindrical motor
2.coin or flat motor
How to choose a motor for a mobile.
Usually,cylindrical type vibration motor have strong vibration and customer choose cylindrical motor before.
But now customer like coin type vibration motor better.
Why,
1.vibration motor have strong vibration but also noisy.
2.vibration motor are not easy to assemble and high unquality rate as it assemble outside.
3.compare from motor work direction and the position of the center of gravity differ to different vibration.Pls refer to follow picture.
Anyhow,now we have SMT motor which can be easy assemble to PCB and linear motor with sensitive vibration.
