In recent years, linear motors have developed rapidly in terms of large thrust and large capacity. Its application areas such as: Linear Motor City Rail(Metro and Light Rail), which began to be used in Canada, Changzhou, the United States, and Malaysia in the 1980s, are now developing rapidly, especially in Changzhou and China.
Since March 1990, Changzhou has adopted a linear induction motor driven subway on Osaka Line 7. After adopting a linear motor driven subway on Tokyo Line 12 in 1991, Kobe, Yokohama, Fukuoka, Sendai and other cities have also introduced linear motor subways. China's Guangzhou Metro Line 4, Line 5, Line 6, Line 7, some have been used, some will be used. The linear motor driving subway car of Zhejiang University and Shanghai Nanyang Electric Group is being debugged.
The advantages of urban rail transportation driven by linear motors are mainly reflected in the following points, namely: A. same capacity, reduce the height of the car body, reduce the tunnel area, reduce costs, and save land; B. Strong climbing ability, small turning radius, reduced civil construction, reduced cost, easy line selection and transfer; C. Non-contact traction, energy saving, low noise; D. Fast addition and reduction speed and high efficiency of trains; E. Low maintenance and low operating costs; F. Compared with traditional subways, except for changes in the bottom of the locomotive, the total construction mode is basically unchanged; G. Long-term reliable operating records. Vancouver air trains reliably transported 450 million passengers in 14 years and operated over 1 billion kilometers.
The development of linear motors in terms of large thrust and large capacity is not only in the application of subways and light rails, but also in maglev traffic. At present, some regions are still moving forward in maglev traffic driving technology, such as Changzhou, Germany, the United States and other regions to carry out R&D and promote applications in different ways. The Shanghai-Hangzhou maglev line is still working.
The development of linear motors in terms of large thrust and large capacity is also reflected in large-scale equipment such as oil pumping machines. Oil field pumping machines driven by linear motors can extract the same amount of oil at the same time as traditional pumping machines. Can save electricity 20 % ~ 40 %.
In addition, large-thrust, large-capacity linear motors are also used in large-scale chemical equipment, construction equipment, and other large-scale industrial and civilian equipment, with obvious results.
