编码器常用来测量伺服电机系统的转角和转速等相关数据。目前市场上使用的主要有光学编码器和磁编码器两种。与前者相比,磁编码器由于不受污垢、粉尘、油污、冷凝以及其他污染物的影响,近年来得到了市场上越来越多的关注。采用先进设计的磁编码器技术可提供与光学编码器媲美的精度(分辨率),并可在提高系统效率的同时大幅降低生产成本。1引言在工业自动化领域,以编码器为代表的速 Encoder commonly used to measure the servo motor system angle and speed and other related data. Currently on the market are mainly used optical encoder and magnetic encoder two. Compared with the former, magnetic encoders have gained more and more attention in the market in recent years because they are not affected by dirt, dust, oil, condensation and other pollutants. Magnetic encoders with state-of-the-art design provide precision (resolution) comparable to optical encoders and dramatically reduce system costs while increasing system efficiency. 1 Introduction In the field of industrial automation, represented by the encoder speed
