Abstract:

In order to meet the development needs of new models of aerospace servos, the angular displacement sensor is required to have a compact structure, high reliability, and be able to adapt to harsh working environments and limited space structures to achieve high-speed measurement and feedback of the servo motor output shaft. A two-redundant multi-turn absolute encoder based on a small modulus reducer is developed. On the basis of a single-turn absolute encoder, through the design of a small modulus reducer, the redundant absolute measurement of the spindle input of 8000rpm high speed is realized Technology, product performance reaches the performance index of similar products of HEIDENHAIN encoder, can withstand high temperature, long working life, good dynamic performance, small space and light weight. System test and simulation analysis show that the design technical scheme is effective and feasible, and can meet the requirements of the servo system.
