Highly flexible absolute integrated encoder system on GMR-basis

摘要

The cooperative project GMR-Flex is funded by the Federal Ministry of Education and Research (BMBF) within the support program "Microsystems 2004-2009". The aim of the GMR-Flex project is the development of a GMR-based absolute rotary encoder system, which is flexibly scalable between module 0.2 and 4 and shaft diameters from 20 to 500 mm. One of the project's primary objectives is an accuracy of 14 bits, which has solely been achieved by optical encoder systems up to now. Furthermore, the system should be easily parameterizable and mountable
