With intelligent concept is deeply rooted in the hearts of the people, more and more intelligent products are used in daily life, we have to mention here is important features of a smartphone: camera.
Both smart phones and other electronic equipment camera parts, all must have a linear motor shell to normal operation.
Next, let's look at the principle of linear motor shell.
Working principle of the linear motor shell with the horn is the same, 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.
From the structure, the motor can be divided into these three categories: shell type structure, the ball bearing 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, effect is the best and the linear motor shell.
Linear motor shell stamping front with customers to develop, strictly make mold design review and examination, improve terminal stamping product development success rate and the efficiency of production, the rationality.
Precision contact: wish you a prosperous business, everything goes well, if you want to learn more dynamic, can scan the qr code, pay attention to the public.
, is committed to precision stamping processing factory of the world's most professional electronic components
