Design of a New Magnetic-Electromechanical Absolute Encoder with High-Accuracy

A new magnetic-electromechanical absolute encoder was designed with high accuracy and low cost integrating magnetic, mechanical and electric technologies. Lap measuring module was designed based on magneto-electric theory; lap and multi-turn type measuring modules were processed with combination by using V-bit cascade algorithm, and then the effective and reliable realization of serial output of location coding signals was attained by taking advantage of exterior interrupt and timer of microprocessor. The practical application showed that the designed magnetic-electromechanical absolute encoder was effective with high-accuracy, stability and reliability.
