小型绝对式矩阵编码器

绝对式编码器具有固定起始点、读数可靠等优点。但传统的绝对式编码器码道圈数多,结构尺寸大,给某些方面的应用带来不便,希望结构尺寸小。本文介绍一种小型绝对式编码器的设计方法,其中包括:绝对式矩阵编码盘的设计;工作原理;矩阵译码方法。传统的14位绝对式编码器最小径向尺寸为φ130mm,而采用矩阵式编码盘,同样位数的编码器径向尺寸可缩小到φ65mm。

Micro Absolute Matrix Encoder

The absolute encoder has such advantages as fixed starting-point, reliable reading, and so on. But traditional absolute encoder is limited in use, because of its large number of rings and large size. So micro encoder is desired. This paper introduces design procedures about a micro absolute matrix encoder, including the design of absolute matrix code disk, working principle, procedure of matrix decode. The minimum radial size of traditional absolute encoder of 14 bits is φ130mm. While using matrix code disk, the radial size of same bit encoder can be reduced to φ65mm.
