Closed-Loop Stepper Motor Drive: Servo-Level Precision, Stepper-Level Cost
The SD6 stepper drive is entirely self-developed—from hardware design and underlying algorithms to upper computer software—possessing full intellectual property rights. Upgrade your motion control architecture with our advanced closed-loop stepper drive.
By integrating high-resolution encoders and intelligent DSP algorithms, this drive completely eliminates the inherent risks of missed steps and stalling found in traditional open-loop systems. It continuously monitors rotor position in real-time and automatically adjusts current and torque, maintaining absolute positioning accuracy even under sudden load fluctuations.
Designed to bridge the performance gap between stepper motors and AC servo motors, our closed-loop drive delivers superior dynamic performance, ultra-low vibration, and minimal heat generation. It supports various control modes, including Pulse/Direction, CW/CCW, and industrial bus communications (such as EtherCAT, Modbus, and Ethernet/IP). Whether you need a compact pulse-type drive for simple upgrades or a high-speed bus controller for complex multi-axis synchronization, this drive offers unparalleled reliability and cost-effectiveness.
