Sino Galvo High speed auto-focus galvo laser head SG2206 High-speed Galvo for fiber laser marking engraving machine
SG2206 type galvanometer has good running stability, high positioning accuracy, fast marking speed, strong anti-interference ability and strong comprehensive performance. The specific characteristics are as follows:
■ Adopt photoelectric sensor imported from the United States.
■ Differential photoelectric sensor accurately detects the position of the motor rotor, with good linearity, small drift, high resolution and repeated positioning accuracy.
■ Precise load design for 10mm lens, high motor assembly precision, reasonable structure, small static friction coefficient and zero offset, to ensure good dynamic characteristics of the system.
■ The driver has the function of position and speed advance detection, which greatly improves the dynamic response performance and scanning speed of the whole system.
■ Designed with overload, overcurrent and reverse polarity protection, making the system more reliable.
■ The whole system adopts electromagnetic compatibility optimization design, with high signal-to-noise ratio and strong anti-interference ability.
■ Solve common problems such as galvanometer motor temperature drift, signal interference and zero drift.
