SG8214 Galvo Scanner

Release time:2021-05-20 10:22  

The model SG8214 galvo scanner has the good running stability, high positioning accuracy, fast marking speed, strong anti-interference ability, the overall performance of SG8214 has reached the international leading level in this field.



The advantages are as following:

■ Adopted the photoelectric sensors which imported from America, and owned the proprietary 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 14 mm 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.

■ 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.
