Principle of linear motor

With intelligent concept is deeply rooted in the hearts of the people, more and more intelligent products are used in daily life, and the use of smart phone it is the most widespread. We have to mention here is important features of a smart phone, camera. Both smart phones and other electronic equipment camera parts, should have VCM motor can run normally. Next, let's know the VCM motor principle of work. VCM motor working principle is the same with the speaker, its structure includes: carrier, coil, magnet, shrapnel, gaskets, etc. , its main principle is: in a permanent magnetic field, by changing the motor coil in the dc current size, to control the position of the spring piece, so as to drive the motor parts in up and down. Structurally, VCM motor can be divided into these three categories: the shell type structure, ball type structure, friction type structure; From the function, can be divided into five categories: open the motor, closed-loop motor, motor, optical image stabilization of six axis motor, motor. There are a lot of realization method of the camera focus, most widely used, the effect is the best and VCM motor. Dongguan precision electronic technology co. , LTD. , a professional provide VCM motor shrapnel, terminals and other stamping customization, high quality, cheap and fine.
