Product Description
Sino-Galvo's galvanometer motors are designed by adopting the magnet-moving structure, combining the most advanced international photoelectric sensor technology and the PDM control mode, and using the -grade processes and technologies.
The model RF8330-3D galvo scanner has the good running stability, high positioning accuracy, fast marking speed, strong anti-interference ability, the overall performance 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.
■ Drives with advanced detection ability of position and speed, greatly improved the dynamic response performance and scanning speed of the whole system.
■ The whole system adopted the optimization Designing of electromagnetic compatibility, with high signal-to-noise ratio and strong anti-interference ability.
