Description
A galvanometer scanner operates as a special type of oscillating motor. The basic principle involves an energized coil generating torque within a magnetic field. Unlike traditional rotating electric machines, the rotor in a Galvo motor system is loaded with a reset torque via a mechanical spring or electronic method. When the coil is energized with a specific current, the rotor deflects to a certain angle, balancing the electromagnetic torque with the restoring moment. This deflection is proportional to the current, similar to a galvanometer, hence the name galvanometer scanner.
The operation of a galvanometer scanner involves inputting a position signal, causing the Galvo motor to swing to a specific angle based on the voltage-to-angle conversion ratio. The entire process employs closed-loop feedback control, comprising five control circuits: position sensor, error amplifier, power amplifier, position distinguisher, and current integrator.
Analog galvanometer scanners are susceptible to electromagnetic interference, leading to scattered points, curved lines, and irregular shading. In contrast, digital galvanometer scanners convert analog signals into digital signals, effectively suppressing environmental interference.
Whether you need a single-axis Galvo scanner or a more complex galvanometer mirror scanner, understanding these principles will help you choose the right system for your laser marking machine.
