The scanning function of laser galvanometer is widely used in all kinds of laser processing technology, especially in the marking process. Let's discuss the study of galvanometer working principle and application. The principle of the galvanometer is: input a position signal, the oscillating motor (laser galvanometer) will swing a certain angle to a certain voltage and angle conversion ratio. The whole process adopts closed-loop feedback control, which is operated by position sensor, error amplifier, power amplifier, position divider, current integrator and other five control circuits. The principle of digital laser galvanometer is to convert analog signals into digital signals on the principle of analog laser galvanometer.
