In recent years, with the aerospace, microelectronics and other high-tech industry continues to develop, the manufacturing equipment processing quality and positioning accuracy of the movement put forward higher requirements. Linear motors have a simple structure, no contact, no wear, low noise, fast speed, and precision, as a transmission device that converts electrical energy directly into linear motion mechanical energy without any intermediate switching mechanism. Compared with the traditional transmission mode, High power, so that the linear motor as a modern manufacturing equipment in the ideal drive components. Now, the linear motor modern manufacturing equipment has played an important role.

　　The linear motor breaks the traditional rotary motor + ball screw to convert the mechanical rotary motion into a mechanical linear motion. It does not require any intermediate links to directly drive the controlled object for linear motion, and thus has the unique advantage:
　　1. The system is simple, the motion inertia is small, the system rigidity is high, the quick response characteristic is good, there is much more increase and decrease speed than the traditional rotary electric motor. Since it is not subjected to centrifugal force as a rotating electric machine, the linear velocity can be unrestricted.
　　2. Small part of the intermediate parts and wear, etc., for a given path to achieve high-speed tracking and positioning. System maintenance is simple, reliable, long life.
　　3. Simple structure, relying on electromagnetic thrust drive, so the movement is quiet, low noise, thus improving the working environment.
　　4. The thrust is large (up to 22000N), its speed, acceleration is higher than the ball screw several times, the working stroke can be infinitely long, the length of the feed stroke is not restricted.
　　Ultra-precision machine tools have been applied linear motor and hydrostatic bearings or air static pressure bearing spindle, air hydrostatic guide. International air guide straightness up to 0.1 ~ 0.2 m / (250mm), so that the processing accuracy of a few hundredth of a micrometer, and achieved good results. Precision and ultra-precision machining technology to ensure the ultra-precision product quality of new technologies such as the microelectronics industry. Such as the manufacture of large space telescope mirror, large-scale integrated circuits, chips, micro-robots and so on.
　　EDM equipment using linear motor, not only improve the processing accuracy, greatly improving the production efficiency, but also to expand the scope of processing, so difficult to use EDM in the past complex parts can also be processed
　　Application of linear motor-driven stamping equipment not only energy saving, material saving, reduce noise and improve work efficiency, but also to effectively improve the working environment, reducing the traditional personal injury accidents prone press equipment. Due to non-periodic mechanical noise, energy-saving effect is obvious, stamping tonnage, operating frequency, punching speed adjustable; Vertical, horizontal or a variety of oblique installation, to meet the needs of different processing, double-headed stamping, improve work Efficiency; With automatic control function, the use of intelligent control system, easy to automate the production; With a variety of safety protection workers can avoid personal injury accidents; Significantly shorten the manufacturing cycle, a large number of materials, significantly reducing costs.
　　Not only in all kinds of high-speed, precision machining, EDM, stamping equipment has a wide range of applications. But also in the grinding machine, sawing machine, laser cutting machine, plasma cutting machine and other processing equipment applications have achieved very good results.
　　Manufacturing equipment using linear motor technology to make the overall level of manufacturing equipment on a large step at the same time, but there are still fever, magnetic isolation and protection, load interference and applied to the vertical feed mechanism when the self-locking and gravity acceleration And other issues. With the new magnetic materials, motor cooling methods, more advanced control technology development success, and the further development of linear motor research, in addition to the current electromagnetic drive, there are piezoelectric micro-drive, hot micro-drive, direct light Micro-drive, micro-drive micro-drive, polymer micro-drive and other forms, so that its application in the manufacturing equipment will be more and more widely, will further promote the modern manufacturing equipment, great changes in equipment technology.
