前言感应同步器是利用两绕组(中间隔一薄层间隙)的感应耦合原理制成的一种精密测量元件,用于角度和直线位移的准确测量和控制,角度精度小于1秒,直线精度小于50微时,在某些特殊应用中还可有更高的精度。感应同步器有直线式和旋转式两种(图1和图2),广泛地应用于不同的领域。旋 Introduction Inductosyn is a precision measuring device made by the principle of inductive coupling between two windings (separated by a thin gap) for accurate measurement and control of angle and linear displacement. The angle accuracy is less than 1 second and the linear accuracy is less than 50 micro-hours, in some special applications can also have higher accuracy. Induction synchronizers have two types of linear and rotary (Figure 1 and Figure 2), widely used in different fields. Spin
