In the recent years, with the rapid development of automatic control technology and microcomputer, higher requirements are placed on the positioning and accuracy of various automatic control systems. In this case, the traditional Of the linear motor drive motor drive, has been far unable to meet the requirements of modern control systems, linear motors are now more and more countries in the world, widely used in various industries, mainly in the following areas:

1. The application of linear motor platform in CNC machine tools: The drive of traditional machine tool relies on screw drive which has a series of unfavorable factors, such as length limit, mechanical gap, friction, distortion, pitch period error and so on Linear motor not only does not have this defect, and the structure is simple, the accuracy of the screw can be 10 times or even 100 times, the acceleration can be more than 20 times the traditional machine tools, high speed, high speed, high acceleration, high precision CNC machine tools only use linear motor platform To be able to meet the requirements.

2. Linear Motor Platform IT industry applications: PCB board positioning, drilling machines, computer hard drives, floppy disks, CD-ROM head positioning devices, printers, scanners and so on. Such as Japan's Matsushita will use linear motor platform for driving digital scanners, so that the total weight of the scanner to reduce, start the thrust to improve, reduce image fluctuations, the scanning speed increased nearly 5 times.

3. Linear motor platform in the logistics and transport system: the postal system of postal parcels, printed materials logistics sorting, transmission lines, such as Japan Tokyo Tama postal large-scale postal sorting machine, Shenzhen Customs also adopted by Zhejiang University to provide linear motor platform logistics Sorting line. At present, many industries such as electricians, electronics, machinery, chemicals, pharmaceuticals and other production lines and assembly lines also have some use of linear motor platform transmission line.

4. Linear motor platform in traffic applications: Linear motor platform for traffic is the most typical maglev train, which changed the traditional rail vehicles by rail wheel friction to promote the way, the use of magnetic suspension body, linear motor drive technology, It is a major breakthrough in the history of traffic technology to make the train float on orbit on the track and is praised as an ideal means of transport in the 21st century. Maglev vehicles compared with existing conventional vehicles, the main advantages are: speed (500km / h); safe, no rollover; no noise vibration; small footprint; strong climbing; simple structure; energy saving. Many countries at home and abroad, such as Germany, Japan, the United States, France, Britain, Russia, Canada, South Korea, Switzerland, Sweden and China have already invested in this aspect of research and development, especially Germany and Japan.

5. Linear motor platform used in civil development is also very rapid, linear motor platform doors, windows, curtains, linear motor platform washing machines, air conditioners, refrigerator linear motor compressor, linear motor platform with home knitting machine and Sewing machine, fried tea machine and so on. Especially with a linear motor platform elevator, it has the advantages of simple structure, material saving, space saving, high speed, low noise and energy saving.

6. Linear Motor Platform In the military: linear motor platform has also been some military applications, such as the previously described linear motor platform submarines, as well as linear motor electromagnetic guns, the United States had announced in 1995 has been completed. In addition, on some military installations such as military shooting ranges, military simulation systems, the launching of military combat weapons such as missiles and the like.
