China's stepper motor industry

In the past decade, China's stepper motor industry has achieved a systematic transition from 'open-loop drive' to 'intelligent closed-loop' through scientific and technological innovation. The core path focuses on high-precision control, integrated modules and deep integration of industrial Internet. Leading enterprises such as Lei Sai Intelligent have launched the CL1 series closed-loop stepper driver, which integrates a 26 bit high-resolution encoder and adaptive algorithm to completely eliminate step loss, improve high-speed response performance by 40%, and cost only 50% of servo systems; Kinco is the world's first iSWV vertical integrated steering wheel module, which integrates motors, reducers, encoders, and drivers into a single package to achieve omnidirectional movement and power-off memory. It is widely used in humanoid robots and AGV chassis, with a power density increase of 35%; Huichuan Technology has developed the STD60N series stepper driver based on the EtherCAT bus architecture, which supports AI adaptive load compensation and has a dynamic response bandwidth of up to 3.5kHz, meeting micro level positioning requirements such as semiconductor packaging and medical imaging. The 5G private network and digital twin platform are fully deployed on the production line, achieving millisecond level collaboration and predictive maintenance of equipment, and increasing OEE by more than 22%. The '15th Five Year Plan' for the development of intelligent manufacturing clearly lists stepper motors as key basic components, and the new national standard GB/T 38872-2025 will be implemented in 2026, unifying the intelligent drive interface protocol. The industry has formed a full chain localization capability of 'materials control systems application', and the proportion of products exported to high-end markets in Europe and America has exceeded 38%.
