Encoders are the most widely used feedback devices for electric motor control, capable of delivering precise position and speed feedback for closed-loop performance. With numerous technology options ...

Abstract: In order to improve resolution of multi-pole encoder and realize absolute output, a novel absolute multi-pole encoder structure based on calibration was proposed. Two ring alnicos, defined ...

Abstract: To improve the subdivision accuracy of the absolute photoelectric shaft encoder, a particle swarm optimization (PSO) algorithm is proposed for error ...
