What is a Galvanometer?

Galvanometer is an excellent vector scanning device. It is a special oscillating motor.The basic principle is that the energized coil generates torque in the magnetic field, but unlike the rotating electrical machine, the rotor is reset by a mechanical spring or electronic method. The size is the angle of the rotor from the equilibrium position It is proportional. When the coil is deflected to a certain angle with a certain current, the electromagnetic torque and the return torque are equal, so it cannot rotate like an ordinary motor, only deflection, and the deflection angle is proportional to the current, which is proportional to the current meter. Similarly, the galvanometer is also called galvanomet ric scanner. The scanning galvanometer is a professional term called Galvo scanning system. The so-called galvanometer can also be called an ammeter. Its design idea completely follows the design method of the ammeter. The lens replaces the meter needle, and the signal of the probe is replaced by a computer-controlled DC signal of -5V-5V or -10V-10V. To complete the scheduled action. Same as the rotating mirror scanning system, this typical control system uses a pair of folding mirrors. The difference is that the stepper motor that drives the lens is replaced by a servo motor. In this control system, the use of position sensors The design ideas of the negative feedback loop further ensure the accuracy of the system, and the scanning speed and repeat positioning accuracy of the entire system reach a new level.

The beauty scanning galvanometer is a three-lens vertical light-entry medical and cosmetic galvanometer assembly, which is characterized in that it includes an inner bracket, an outer bracket, a fixed focus frame, an X-scan motor, a Y-scan motor and three lenses The inner bracket is installed inside the outer bracket, and the inner bracket and the outer bracket are fastened by screws at the bottom; the X-scanning motor is vertically installed on the top of the outer bracket, and the Y-scanning motor is horizontally installed on the left side of the outer bracket. The three lenses are X lens, Y lens and 45 ° mirror, respectively. The X lens is connected to the X scanning motor through the X scanning motor shaft and can swing around the X scanning motor shaft. The Y lens is connected to the X scanning motor shaft through The Y-scan motor is connected and can swing around the Y-scan motor axis, 45 °

1. High-speed scanning galvanometer

In simple terms, the galvanometer system is a high-precision, high-speed servo control system composed of a driving board and a high-speed swing motor. It is mainly used for laser marking, laser internal carving, stage lighting control, laser drilling, and dot matrix. Laser medical beauty industry, etc.

Scanning galvanometer

At present, there are many internationally renowned brand galvanometers and the most used in our country are American GSI, American CTI and German SCANLAB. Among them, the German SCANLAB galvanometer has the best quality, fastest speed, most stable performance and highest price. Secondly, it is characterized by its fast speed and stable performance. US GSI galvanometer is the most cost-effective.

Stage light galvanometer

At present, the best ones in China are Longhu galvanometer / Shanghai Naiqun Galvanometer / Shenzhen Hongguang Electronics, which are relatively famous. The stage galvanometer has a 5K closed-loop galvanometer according to the speed ratio. The spring device is used to rotate the angle into 45 degrees , 10K, 20K 30K 40K 50K 60K. Other galvanometers above 10K are completed with feedback circuits. The scanning speed of a 10K galvanometer is equivalent to running 10,000 points per second.

Beauty galvanometer

At present, the most famous domestic galvanometer is the galvanometer. The galvanometer is completed with a feedback circuit. The galvanometer has a maximum beam spot of 10 spots. The 10-spot lens scanning speed reaches 65535 points per second. Can reach this speed.
