Product Features
■ The differential optoelectronic sensor precisely detects the motor rotor's position, offering excellent linearity, minimal drift, and high resolution as well as outstanding repeat positioning accuracy.
■ Precisely designed load for the 10mm lens, featuring high motor assembly accuracy, a rational structural design, minimal static friction coefficient, and negligible zero-position offset—ensuring excellent dynamic system performance.
■ The driver features advanced position and velocity feedback detection, significantly enhancing the system's dynamic response performance and scanning speed.
■ The design includes overload, overcurrent, and reverse-polarity protection, ensuring more reliable system operation.
■ The entire system features an electromagnetically compatible, optimized design, delivering a high signal-to-noise ratio and strong anti-interference capability.
■ Addressed common issues such as galvanometer motor temperature drift, signal interference, and zero-position drift.
