According to the system provided by the embodiment of the invention, through the power supply 302 and the electric equipment 301 provided by the embodiment of the application, the technical problem that the price of a special power supply for customizing a galvanometer in a laser marking machine in the related technology is multiplied by the price of a common power supply, so that the corresponding manufacturing cost is increased is solved, and the technical effect of improving the product competitiveness is further achieved.

Optionally, powered device 301 is a galvanometer controller in a laser marking device.

The vibrating mirror in the laser marking machine is a special swing motor, and the basic principle is that an electrified coil generates torque in a magnetic field, but different from a rotating motor, a rotor of the vibrating mirror is added with reset torque through a mechanical torsion spring or an electronic method, the size of the reset torque is in direct proportion to the angle of the rotor deviating from balance, when the coil is electrified with certain current and the rotor deflects to a certain angle, the size of the electromagnetic torque is equal to that of the reset torque, so that the vibrating mirror cannot rotate like a common motor and can only deflect, and the deflection angle is in direct proportion to the current.

Optionally, the galvanometer controller has a ground line.
