SG7210 vibrator has good operation stability, high positioning accuracy, fast marking speed and strong anti-interference ability. Its comprehensive performance is far better than any galovanometer produced in Germany, reaching the technical standards of similar products at home and abroad.
The specific characteristics are as follows:
* Optoelectronic sensors imported from the United States, with independent intellectual property rights.
* Differential photoelectric sensor accurately detects the position of motor rotor, with good linearity, small drift, high resolution and repeated positioning accuracy.
* Accurate load design for 10mm lens, high precision motor assembly, reasonable structure, small static friction coefficient and zero offset, to ensure good dynamic characteristics of the system.
* The driver has advanced detection function of position and speed, which greatly improves the dynamic response performance and scanning speed of the whole system.
* Design with overload, overcurrent and reverse connection protection, make the system more reliable operation.
* The whole system adopts electromagnetic compatibility optimization design, high signal-to-noise ratio, strong anti-interference ability.
* Solve common problems such as temperature drift, signal interference and zero drift of the galvanometer motor.
