SG8220-G galvanometer adopts all-aluminum integrated design with high sealing grade and strong adaptability to environment. At the same time, the water cooling circulation system is adopted to effectively control the working temperature of the galvanometer and ensure the whole machine to run continuously for a long time without failure. 

The advantages are as following:

■ Adopted the photoelectric sensors which imported from America, and owned the proprietray intellectual property rights.

■ Differential photoelectric sensor for accurate detection of motor rotor position, good linearity, lower drift, high resolution and repeat positioning.

■ Accurate load design for 20mm mirrors, high accuracy of motor assembly, reasonable structure, very small static friction coefficient and zero offset, all ensured the best dynamic characteristics for the whole system.

■Water cooling structure is adopted to effectively control the working temperature of galvanometer.

■ Drives with advanced detection ability of position and speed, greatly improved the dynamic response performance and scanning speed of the whole system.

■ Design of overload, over-current and reverse connect protection, makes the system running more reliable.

■ The whole system adopted the optimization Designing of electromagnetic compatibility, with high signal-to-noise ratio and strong anti-interference ability.

■ This scanner system solved the common problems of motor temperature drift, signal interference and zero drift, etc.
