The application of linear motor in information equipment is mainly in the computer equipment and its input and output equipment. In the computer host, in the hard disk device, the linear servo motor was first used on the IBM2314 main drive, and later on the IBM333, Panasonic Japan. The company also adopted linear servo motors on 3.5-inch disk drives. Japanese Kobelco Electric Co. and Fujitsu Co., Ltd. also manufactured linear stepping motors for floppy drives. With linear motors, computers effectively shortened access. Time, improve work efficiency. In addition, linear motors are also used in computer input and output devices. For example, Japan's Kobelco Electric Co., Ltd. and Fujitsu Co., Ltd. used linear stepping motors and linear direct current motors for printers, achieving improved resolution and stopping accuracy and better acceleration characteristics. Panasonic Corporation of Japan used a linear servo motor to drive a digital scanner, which reduced the total weight of the scanner, increased the starting thrust, reduced the image fluctuation, and increased the scanning speed by nearly five times.

As for the existing high-precision plane plotters at home and abroad, almost all plane linear stepping motors are used, which realize the high speed, high accuracy, high reliability, and durability of the plotter. This type of plotting machine, the Institute of Electrical Engineering of the Chinese Academy of Sciences and the Shanghai 21 institute had been successfully tested as early as the 1980s.

The applications of linear motors in automation equipment include new types of pen recorders, automatic winding machines, camera electromagnetic shutters, automatic bar code readers, and so on.

The development of linear motor technology has experienced a long history and several wave-like developments. Compared with non-linear motor drives, the new linear motor-driven device has a simple structure, no contact, and no wear. The advantages of low noise, high speed, high precision, and flexible combination are obvious, but due to the side-effects caused by the breaking of the magnetic circuit in the linear motor itself and the large air gap in the installation, it is in some straight-line motions. Whether or not a new type of linear motor is used to drive the device or system, the trade-offs between the advantages and disadvantages must be weighed, and a linear motion device or system that can take full advantage of the advantages of the linear motor should be selected for development and application. Today, with the rapid development of science and technology, in the place where some rotating electric machines or other drive devices are incompetent or barely able to cope with it, we are looking for a place where linear motors can give full play to their advantages, and seek their own development in the course of satisfying human needs and improving the good wishes of mankind. The prospects are broad, but the choice is cautious.
