Differential photoelectric sensors detect the position of the motor rotor with good linearity, low drift, high resolution and repeatability.
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.
Drives with position and speed overrun detection, greatly improving the dynamic response performance and scanning speed of the entire system
Designed with overload, overcurrent and reverse connection protection for more reliable system operation。
The whole system adopts electromagnetic compatibility optimised design with high signal-to-noise ratio and strong anti-interference capability.
Solves common problems such as galvanometer motor temperature drift, signal interference and zero drift.
