Product Features
■ The differential optoelectronic sensor precisely detects the motor rotor's position, offering excellent linearity, minimal drift, and high resolution along with superior repeat positioning accuracy.
■ Precisely designed load for the 20mm lens, featuring high motor assembly accuracy, a rational structural design, minimal static friction coefficient, and negligible zero-position offset—ensuring excellent dynamic system performance.
■ Employs a water-cooling structure to effectively manage the galvanometer's operating temperature.
■ 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, optimally designed architecture with a high signal-to-noise ratio and strong anti-interference capability.
■ Addressed common issues such as galvanometer motor temperature drift, signal interference, and zero-point drift.
