For the hard disk, use a coil motor to talk with Mao. Tongmao customer service personnel have encountered many problems related to customer consulting computer hard disk motors in their daily work. In this period, with the help of this platform, the small editor has widely reported that the traditional mechanical hard disk usually uses two motors, namely the spindle motor and the magnetic head control motor. The spindle motor is generally a DC brushless motor. The old hard disk head control motor also uses a step motor, and the new hard disk uses a coil motor.
The so-called coil motor is actually a direct-drive motor that uses a mechanical structure without iron cores. This 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 above advantages of the coil motor that it is widely used in hard disk head control.
However, the sound coil motor here is slightly different from the Tongmao sound coil motor. At present, Tongmao has not developed a sound coil motor suitable for hard disks. Tongmao's high-performance, high-quality audio coil motors designed, developed, produced, and manufactured are mainly used in the semiconductor industry, medical care, Valve operation, shock absorber system, micro-machine tool industry, and aerospace.
The Tongmao ring motor includes a cylindrical ring motor, a swing ring motor, a flat ring motor, a rectangular ring motor, and an axial ring motor. Tongmao can provide a linear ring motor with a peak value of 5000N and a stroke of 300mm; Can provide a swing coil motor with a peak value of 50NM and a swing angle of 120 degrees.
Tongmao Motor has been deeply ploughing in the field of coil motors for many years. It has the technical experience of Europe and the United States in the industry. It uses customer appeal as its design direction and specializes in customizing sound coil motors with reasonable performance for customers.
