Voice coil motor is a special form of direct drive motor.

The working principle of the voice coil motor is that the energized coil (conductor) will generate a force (Lorentz force) when placed in a magnetic field, and the magnitude of the force is proportional to the current applied to the coil. The motion form of voice coil motors manufactured based on this principle can be linear or circular. At present, our products are all linear motors.

The voice coil motor has a simple structure, high precision, high response, maintenance-free, no cogging effect, and no need for commutation. It is especially suitable for short-stroke, fast-response, and high-precision closed-loop servo control.

The voice coil motor is applied to the power unit of the baby cradle. On the one hand, it can solve the problem of low electromagnet strength and large noise, and on the other hand, it also solves the problem that the motor cannot dynamically adjust the speed. The thrust of the voice coil motor is proportional to the current applied to the coil, and the shaking speed of the shaker can be adjusted steplessly, making the shaker more comfortable and quieter.
