Development of two-redundant multi-turn absolute encoder based on small modulus reducer

In order to meet the development needs of aerospace servo technology, angular displacement sensor, which compact structure, high reliability, and be able adapt harsh working environments is used for measurement feedback speed motor output shaft. The design a two-redundant multi-turn absolute encoder based on single-turn precision small modulus reducer, realizes shaft at 8000 rpm. Product performance meets technical indicators similar products HEIDENHAIN encoders, can withstand temperature, long life, good dynamic performance, space light weight. System test simulation analysis show that scheme effective feasible, requirements system.
