一、前言直线感应同步器数显装置是由检测元件,电气测量线路和显示器三部份组成,用以准确、迅速、不停车地直观显示机床运动部件位移的装置。检测元件是由具有沿位移方向均匀、连续绕组的定尺,和具有许多分段绕组组成的两相正交绕组(正、余弦绕组)的滑尺,相对相距0.25±0.05mm 安装而成,当滑尺绕组通以正余弦激磁信号:
I. INTRODUCTION Linear induction synchronizer digital display device is composed of three parts: detection element, electrical measuring circuit and display, which can display the displacement of moving parts of machine tool accurately, rapidly and without stopping. The detection element is a sliding scale with two-phase orthogonal winding (positive and cosine winding) which is composed of a plurality of segment windings with a uniform and continuous winding along the displacement direction, which are arranged at a distance of 0.25 ± 0.05 mm Slider winding pass with sine and cosine signals:
