Precision Stepper Motor Drives: Powering Smooth and Accurate Motion
The SD5 is a high-performance two-phase digital stepper motor driver developed entirely by our company, based on a DSP control platform, supporting three control modes: pulse + direction, RS485, and CANopen, and compatible with the 42~86 series two-phase stepper motors. The driver is equipped with intelligent algorithms such as adaptive motor parameter recognition, vibration suppression, and self-tuning, supporting up to 51,200 subdivisions to achieve ultra-low vibration and highly smooth operation. Peak current 0.5A~8A, power supply range DC 24V~72V, widely used in 3C electronics, laser processing, engraving machines, automated production lines, AGVs, and other scenarios.
Designed for demanding applications, our stepper drivers use advanced segmentation technology to effectively reduce vibration and acoustic noise, ensuring silent operation even at high speeds. At the same time, it features comprehensive overcurrent, overheating, and overvoltage protection functions, giving you peace of mind to ensure equipment safety and maintain stable system operation. Our product range offers a variety of configurations, from compact low-power modules to high-torque industrial solutions, all featuring flexible interface options including pulse/direction, analog signals, and industrial bus communication.
Versatile Applications Across Industries
Our stepper motor drives are engineered to meet the rigorous demands of a wide range of industries. Key applications include:
Industrial Automation & CNC: Precision axis control for CNC milling machines, laser cutters, and automated assembly lines.
3D Printing & Additive Manufacturing: Smooth and accurate extruder and print head movement for high-quality prints.
Robotics: Reliable joint actuation and precise positioning for robotic arms and autonomous mobile robots.
Medical & Laboratory Equipment: Accurate fluid handling in infusion pumps and precise positioning in diagnostic imaging systems.

Why choose the SD5?
Most drivers on the market use reference chip solutions, with fixed parameters that cannot be changed. SD5 is fully self-developed from the DSP underlying layer to the upper computer protocols; whatever you want to change, we can change.
Should the protocol be connected to your own controller? Yes, you can.
Need a customized power-on self-check process? Yes, you can.
Custom IO special features? Yes, you can.
Custom debugging software? Yes, you can.
