About the accuracy of linear motor platform. Linear Motor Platform is one of the main products of Tongmao Electronics Co. , Ltd. in Kunshan. It is also one of the products with more daily customer consultation. Just like online clothes shopping, guides need to know the user's height, weight, girth and other parameters in order to recommend the appropriate size, and buy linear motor platform products are the same We also need to know the actual use of total travel, effective travel, positioning accuracy, repeatability accuracy, speed and other requirements, in order to recommend a suitable linear motor platform. 

     Other parameters are quite easy to understand, then what is the positioning accuracy, what is the repetition accuracy? I'm sure there's a lot of people who don't know the difference. This issue is a systematic analysis for you.

     Positioning accuracy refers to the actual position of the linear motor platform after it has stopped running, and the error of the position you require. The error can be measured by laser interferometer, which can be used as the basis of accuracy analysis or positioning accuracy compensation. Of course, linear motor platform in addition to single-axis, there are cross, Gantry and other combined structure. In order to reach a position, the multi-axis system needs the coordinated movement of all axes. The positioning accuracy of the whole machine is not only related to the positioning accuracy of all axes, but also to the rigidity of the mechanical system The accuracy of the feedback system, the resolution and the precision of the drive and control system are related. The repeatable positioning accuracy is an error caused by positioning the same position many times in the past. For example, if a single axis is required to move 200 mm, the result is that first it actually moves to 200.01 mm and then to 199.99 mm after repeating the same motion. The error is 200.01-199.99-0.02 mm, that is, the repeatable positioning accuracy is usually expressed as 0.01 mm.

     Kunshan's standard series linear motor platforms are available in HPL / SPL, HPL / XY / SPL, XYZ / HPL / SPL and can be customized to meet customer requirements.
