U-type linear motor used to position. It is positioned with a grating ruler. What is the grating ruler?

     The linear encoder we often call is also called a position encoder and consists of a readhead and a scale. Raster encoders are commonly used position and velocity sensors and are often used as feedback elements in motion servo systems. The accuracy of the grating encoder has a crucial role to the performance of the system.

     The grating ruler is a high-precision linear displacement sensor composed of a light source, a condenser lens, a scale grating, an indicator grating, and a silicon photocell. The scale is the most used measuring device in the closed loop control system of CNC machine tools. The grating ruler is usually used with two grating gauges of different lengths and lengths. The long one is called the main grating or scale grating. It is installed on the moving parts of the machine tool and requires the same length as the stroke. The short one is called the indicator grating, indicating the grating and The light source, lens, and photo sensor are mounted on the fixed part of the machine.

     The U-shaped linear motor and grating ruler measurement system form an accurate positioning platform with high positioning accuracy and good stability, widely used in CNC machine tools. The U-type linear motor has the advantages of high acceleration and deceleration, small remote inertia, high sensitivity, high system rigidity, and the grating ruler is a measuring device in a closed-loop control system. Linear motor generally according to the accuracy required by the organization, with the appropriate choice of grating ruler to form a closed-loop feedback, the accuracy of linear motor and grating rule roughly determines the positioning accuracy of the entire system.

     Tongmao Linear Motors will make unremitting efforts to promote the development of China's industrial drive industry, and is committed to becoming a trustworthy voice coil motor and supplier of linear motor manufacturers, which will continue to create value for customers.
