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.
