The hard disk driven by the coil motor(coil motor) is included in the scope of consideration for buying a computer. They all said, "I can't eat hot tofu in a hurry." Buying things is also true. Don't make any decisions when you are impulsive. Take computers, as many as a few thousand, as many as tens of thousands, for the average working family is not a small cost, need to be fully weighed. First of all, you must know your own needs. The computer is bought back to work or to play. In addition, you have to look at the computer's graphics card, memory, and processor. Now the hard disk driven by the coil motor(coil motor) is also included. The scope of consideration.
The ring motor(ring motor) has a wide range of applications, and the hard disk driven by the ring motor(ring motor) is one of its applications. 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(coil motor), where the coil motor(coil motor) is mainly responsible for the movement of the magnetic head arm. The hard disk relies on the servo motor to control the movement of the coil motor(coil motor) while working, so that the magnetic head arm is accurately traced. The hard disk coil motor(ring 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. Paste directly on the head arm, 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 certain 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(sound coil motor) in the hard drive has very little mechanical wear under the support of 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.
When purchasing a coil motor(coil motor), you must pay attention to the purchase channel. In order to ensure the quality of the motor equipment, you must purchase it through a regular manufacturer. When purchasing electrical equipment, you can choose the equipment sold by Kunshan Tongmao Electronics Co., Ltd.. The quality of equipment products provided by the company is guaranteed. At the same time, you can also provide customers with operating instructions or installation videos to make people install and use them. The time is more convenient.
