The linear guide, together with other factors, plays a decisive role in the performance and quality of the linear motor. Linear motor is more and more used to replace the drive device with wear-resistant mechanical transmission parts in industrial application. They can provide high speed and acceleration, good adjustment accuracy and precise positioning.

直线电动机的优点在于，所供给的电能可直接转换成线性运动，完全不需要任何用于转矩转换机械的中间元件直线电机的应用领域非常广泛，包括医疗技术、光学、电子、纺织工业、机械制造、装卸输送及包装工业等等。例如，电子结构元件的制造和加工的工艺过程的要求非常高：尺寸为1mm×0.5mm的电子元件必须以非常高的精度与插装的性进行定位。电子工业中插装自动装置的操作周期时间常常小于0.5s，驱动装置必须达到5μm的定位精度同时达到很高的加速度值对机械的要求特别高这种使用直线电机可以达到的加速度又对直线导轨的机械结构提出了很高的要求。

The advantage of linear motor is that the electric energy supplied can be directly converted into linear motion without any intermediate components used in torque conversion machinery. The application fields of linear motor are very wide, including medical technology, optics, electronics, textile industry, machinery manufacturing, loading and unloading transportation and packaging industry, etc. For example, the manufacturing and processing process of electronic structural components requires very high requirements: electronic components with a size of 1 mm × 0.5 mm must be positioned with very high accuracy and safety of insertion. In the electronic industry, the operation cycle time of the plug-in automatic device is often less than 0.5 s, and the driving device must reach the positioning accuracy of 5 μ m, and at the same time, it has a very high requirement on the mechanical structure of the linear guide rail.

直线电机在操作中会产生很高的持久性的轴向力。导向装置必须吸收所出现的3000N的力。因此在高动态的运转应用中要求要有重量轻、刚性高并且坚固的机械导向装置。机台水平的校正。直线导轨要求用两个等高量块和一大理石量尺放在安装基面上，放上精密的水平仪调试底座水平，要求是底座中凸（2~3格）直线导轨安装基面粗糙度，平面度，直线度以及外观的检查。

Linear motor will produce high permanent axial force in operation. The guide must absorb the 3000 n force that occurs. Therefore, in high dynamic operation applications, it is required to have light weight, high rigidity and strong mechanical guiding device. Calibration of machine level. It is required to install the guide rail on the base with a straight line (3) and the base plane of the guide rail, which is required to be placed on the horizontal plane of the guide rail.
