自整角機是一種被廣泛應用的微控制電機，它既能作為傳感器測量遠距離機械裝置的角度位置，也可以控制遠距離設備裝置的角度位移。應用跟蹤型模擬信號轉16位數字單片變換器RD-19230，將自整角機輸出的模擬信號轉化為數字角度信號，介紹了自整角機的基本原理，設計了RD-19230與自整角機的接口電路。測試證明，該電路的設計方法可靠性好，精度高，抗干擾能力強，能夠完全滿足高速自整角機控制系統的要求。

　　Abstract:

　　Synchro is a widely used micro-control motor， it is not only used as a sensor to measure the angle and position of the remote mechanical devices， but also control the angle of displacement of remote installations. This article will use the 16-bit monolithic tracking resolver-to-digital converter to transform the synchro output of analog signals into digital signals，introduce the basic principle of synchro and design the interface circuit of the RD-19230 and synchro.Tests prove the good reliability of circuit design， high precision， strong anti-interference， it can fully meet the requirement of rapid synchro control systems.
