本文研究了一种用对分法三级多线旋转变压器进行轴角编码的可行方案。它的优点是传感器线数减少,传感器信号便于长距离直接传输,编码电路简单复用,精级信号单独激磁有利于精度提高,直接对分可得符号位9位。本文是1974—1984年多线旋转变压器角编码方案研究与实践的继续。 In this paper, we study a feasible scheme for the shaft angle coding of the three-stage multi-line resolver. It has the advantage of reducing the number of sensor lines, the sensor signal is easy to direct transmission over long distances, the encoding circuit is simple and easy to reuse, and the fine excitation signal alone is conducive to improving the accuracy. This article is the continuation of the research and practice of the multi-line rotary transformer angle coding scheme from 1974 to 1984.
