Description

technical field [0001] The invention belongs to the field of photoelectric encoders, and in particular relates to a calibration device and a calibration method for an output speed error of a photoelectric encoder. The calibration device is a highly integrated electromechanical system integrating light, mechanics, electricity, calculation and control, and is widely used in the detection of speed errors of real-shaft or hollow-shaft photoelectric encoders. Background technique [0002] With the development of servo control system and automatic control theory, people have higher and higher requirements for the performance index accuracy of the photoelectric encoder, which is a commonly used detection feedback component in the control system. But this does not mean that domestic and foreign manufacturers only need to devote themselves to improving the performance indicators of photoelectric encoders. At the same time, they also put forward higher performance requirements for pho...
