SG2208 Galvo Scanner
The model SG2208 galvo scanner has the good running stability, high positioning accuracy, fast marking speed, strong anti-interference ability, the overall performance of SG2208 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.
