To help you understand the relationship between the coil motor and the hard disk. The hard disk is one of the main storage media for computers. It is used to store user-installed software, downloaded games, music, movies, documents, etc.. It can be said that it is on the computer.
All components have a high status, second only to memory and CPU. When people are discussing the hard disk, it is often impossible to open up a concept, that is, the sound loop motor, then this period, the small editor to help everyone adjust the relationship between the sound loop motor and the hard disk.
The hard disk consists of a disk body(magnetic surface, track, cylinder and sector, etc.), a read and write magnetic head component(three parts: read and write head, drive arm, transmission shaft), and a magnetic head drive mechanism(coil motor, magnetic head drive car and anti-vibration mechanism), Spindle component (bearings and motors).
Hard disk drive head and head arm and servo positioning system as a whole. The servo positioning system consists of a coil behind the head arm and an electromagnetic control system fixed to the bottom plate. Due to the limitations of the positioning system, the head arm can only move between the internal and external tracks of the disc. The motors in the hard drive are all sound coil motors. The mechanical wear under the support of high-speed bearings is very small and can work continuously for a long time.
Sound coil motor is a direct drive type motor, usually using a mechanical structure without iron core, such a structure brings many advantages to motion control. Since there is no iron core, no residual magnetism can be considered when the armature current direction changes, and the output thrust of the coil motor is proportional to the armature current, and the linearity is high. Therefore, the thrust can be stable and smooth, and the Yuli control mode can be applied. It is precisely because of the various advantages of the coil motor that it is widely used in hard drives.
