618 for computers? Remember to evaluate the hard drive driven by the coil motor! There are three days from the start of the 6.18 E-Commerce Festival, and there is less than 24 hours from the cat's cat(6.16 lottery). It is not polite to tell everyone that the audio circle motor has not only reached 30 levels.(full level), and there are twelve, Sitting and waiting to become "Koi"(sniggering). Many people will choose to start the computer on 6.18 days, because the margin of preference is quite large. Here, apply a small compilation of warm tips: Remember to evaluate the hard disk driven by the coil motor.
Sound coil motors are widely used, and hard drives are also listed. The hard disk is mainly composed of a disk body, a control circuit board, and an interface component. The disk body is a sealed cavity. The internal structure of the hard disk usually refers to the internal structure of the disk body; The control circuit board mainly has hard disk, hard disk cache and main control chip and other units. The hard disk interface includes power socket, data interface, and main and subordinate jumper lines.
There are two linear motors inside the hard disk, one is the spindle motor and the other is the coil motor, where the coil motor is mainly responsible for the movement of the magnetic head arm. The hard disk depends on the servo motor to control the movement of the coil motor when working, so that the head arm can be accurately traced. The hard disk coil motor is mainly composed of magnets and coils. The magnet is generally a whole and is fixed on the hard disk shell. The coil skeleton and the magnetic head arm are generally integrated, and some coils have no skeleton and are directly affixed to the head arm. On, The magnetic head arm has bearings, and the coil is located between the magnets. When there is a current passing through the coil, the coil can swing flexibly in a fixed direction to drive the magnetic head arm. The magnetic head arm is generally equipped with some magnetic head signal processing circuits. The entire circuit, Connect to the hard disk main circuit board via a flexible PCB.
The sound coil motor in the hard drive has little mechanical wear supported by high-speed bearings and can work continuously for a long time. The head of a hard disk drive is of small quality and inertia is small, so the search speed of a hard disk drive is significantly faster than that of a floppy and optical drive.
Kunshan Tongmao Electronics Co. Ltd. is located in the industrial city of Kunshan, with good geographical conditions and convenient transportation.
