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.

直線電動機的優點在于，所供給的電能可直接轉換成線性運動，完全不需要任何用于轉矩轉換機械的中間元件直線電機的應用領域非常廣泛，包括醫療技術、光學、電子、紡織工業、機械制造、裝卸輸送及包裝工業等等。例如，電子結構元件的制造和加工的工藝過程的要求非常高：尺寸為1mm×0.5mm的電子元件必須以非常高的精度與插裝的性進行定位。電子工業中插裝自動裝置的操作周期時間常常小于0.5s，驅動裝置必須達到5μm的定位精度同時達到很高的加速度值對機械的要求特別高這種使用直線電機可以達到的加速度又對直線導軌的機械結構提出了很高的要求。

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.

直線電機在操作中會產生很高的持久性的軸向力。導向裝置必須吸收所出現的3000N的力。因此在高動態的運轉應用中要求要有重量輕、剛性高并且堅固的機械導向裝置。機臺水平的校正。直線導軌要求用兩個等高量塊和一大理石量尺放在安裝基面上，放上精密的水平儀調試底座水平，要求是底座中凸（2~3格）直線導軌安裝基面粗糙度，平面度，直線度以及外觀的檢查。

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.
