The theory of linear Motors has long since appeared in the late 19th century, but it was not until the mid-1950s that the theory and application of linear Motors developed rapidly. By the mid-1990s, a number of companies around the world had manufactured linear motor transmissions and implemented them in high-speed machine tool delivery mechanisms. The research and application of linear motor in our country began in the 1970s. It is limited to magnetic materials, control technology, cooling methods, etc.. In recent years, China has entered the stage of industrial development and upgrading of advanced manufacturing industries. In 2002, the opening of Shanghai Maglev trains marked the beginning of a new stage in the research, application and development of linear motors in China.
At present, the linear motor market is basically monopolized by foreign giants. GE, Bosch, Siemens and other companies have linear motor companies. There are 3 or 4 companies in China that can systematically complete the process requirements. Most of the technology comes from universities. Harbin Taifu Company has successfully listed on the Menasdaq. The domestic understanding of linear motors comes from the research of imported production equipment and finds that its core components are a set of linear electric units. More and more domestic enterprises have entered the R&D and production of linear Motors, and the industry demand and market scale have also become larger and larger.
A simple estimate of the potential of linear motors in China assumes that linear motion and circular motion each account for half of the modern manufacturing industry, and that the costs of the two movements are close to each other. According to calculations, the total sales volume of electric motors in China in 2009 was more than 100 billion yuan. Linear motors have at least tens of billions of yuan in market demand each year.
Development imperative
China vigorously develops advanced manufacturing industry, linear motor industry as its implicit basic industry, should be valued and accelerated development, linear motor to advanced manufacturing is of great significance.
First, linear motors have a wide range of manufacturing applications. These industries include: machine tools, measurement, drilling, milling, electronic assembly, grinding, laser cutting, screen printing, semiconductors, adhesive placement, wafer processing, label bonding, lead wire welding, ion implantation, plate printing, textile machinery, etc.. Through the introduction of linear motor control system, not only can the machining precision and efficiency of these industries be greatly improved, but also reduce the wear and energy consumption. At the same time, it is also an industrial upgrade for these industries.
Secondly, the use of linear motor, labor intensive enterprises in China to improve the productivity of the promotion role. Many labor-intensive industries, such as food, batteries, and toy processing companies, usually require a lot of manpower. If the production line is upgraded to an automated production line driven by linear Motors, it will help enterprises overcome the "labor shortage" and ease the pressure caused by the rising labor costs. It will work.
Then, the development of the linear motor industry can quickly close the technological gap between China and the developed regions of the world. The characteristics of linear motor such as high speed, high precision and high thrust determine its hard demand in scientific research. People use linear motors to drive magnetic levitation trains to speeds of more than 500 kilometers per hour, eject an aircraft to speeds of several hundred kilometers in a matter of seconds, and process various components with micron precision. It can be imagined that without the development of linear Motors, research and development in many high-tech fields will be difficult. (Information source from network)
