一、前言直线感应同步器在数显和数控系统中作直线位移量的检测和定位器件用。由于仅采用一块定尺和一块滑尺经常不能满足测量范围的要求,因而要将几块定尺接长使用。定尺的接长使用除在安装调试中应采取一定措施外,还与其本身结构有关,其主要的影响因素有:(1)定尺基板长度应在给定的公差范围内;(2)印刷绕组导片在定尺基板上布置的位置要正确;(3)要接长的几块定尺的直流电阻值要近似相等。需要接长使用的定尺,就必须满足上述的全部条件。在生产单位发付给用户的每块定尺,都要做好 I. Introduction Linear induction synchronizer for digital display and numerical control system for linear displacement detection and positioning devices. As only using a fixed length and a slider often can not meet the requirements of the measurement range, so you want to use a few pieces of length. In addition to the length of the long connection in the installation and debugging to take certain measures, but also its own structure, the main influencing factors are: (1) length of the substrate length should be within the given tolerance; (2) printing Winding guide in the ruler substrate layout to the correct position; (3) to take a long piece of the length of the DC resistance to be approximately equal. The length of the need to use the length, you must meet all of the above conditions. In the production unit sent to the user every fixed length, should be done
