摘要: 本文提出一种轴角-交流-数字转换器--小值轴角编码器.它以电压比较式逐位编码原 理为基础,采用小值编码和符号位编码组成一种全角变数字的编码方案.它的角测元件是三 角波旋转变压器.因为三角波旋转变压器的特性是分段线性的,所以该编码器精度高,可靠 性高,线路简单,成本低.Abstract: This paper presents a shaft angle to alternating current voltage to digit converter which is called the small-voltage shaft encoder. Based upon bit by bit coding of voltage comparism type it uses the small voltage code and the sign bit code to form a scheme of converting all-range angle to digit. The angular measuring element is a triangular wave rotary transformer. As the voltage characteristic of the rotary transformer is sectionally linear, therefore this coder has performance of high precision, high reliability, simple circuit and low cost.
