Deep-Tech Source Manufacturer
of Motion Control

Shenzhen Xinghuo Automation Technology Co., Ltd. -- operating under the brand Sefow Motor -- is a certified stepper motor manufacturer in China with over a decade of continuous R&D and production experience since its founding in 2012. Headquartered and manufactured entirely in Shenzhen, China, we serve global machinery OEMs, system integrators, and automation equipment builders across more than 50 countries.

Our core engineering portfolio encompasses the full motion control stack: stepper motors (open-loop and closed-loop), brushless DC (BLDC) motors, AC servo motors and drives, multi-axis PLCs (Programmable Logic Controllers), industrial HMIs (Human-Machine Interfaces), and fully customized PCBA drive boards for non-standard industrial equipment. We are an OEM stepper motor manufacturer and a CE certified motion control supplier -- not a trading company.

Our philosophy is "High Integration, Small Footprint, Less Wiring." Every system we ship -- from an integrated closed-loop stepper motor to a complete HMI+PLC all-in-one panel -- is pre-validated as a matched bundle, eliminating the protocol compatibility headaches that arise when sourcing motors from brand A and PLCs from brand B. Native EtherCAT, CANopen, and RS485/Modbus RTU support is standard across our product lines.

We hold the designation of National High-Tech Enterprise and have been awarded China's prestigious "Specialized and Sophisticated" (专精特新) enterprise status -- recognitions that validate our independent intellectual property, patent portfolio, and proprietary algorithm development. Our founder and Chief Scientist, Dr. Chen Zhanjun, holds a PhD from the Chinese Academy of Sciences (CAS) and serves as a graduate tutor at multiple leading universities.

With 22% of our approximately 45-person team dedicated to R&D, we develop closed-loop stepper algorithms, FOC brushless motor control, and PLC/HMI integration software entirely in-house. This depth of engineering capability allows us to function as a genuine drop-in replacement for legacy European brands such as Siemens, Beckhoff, and Maxon -- at 30-40% lower BOM cost -- while maintaining CE/RoHS compliance and full protocol compatibility.

Our industrial BLDC motor factory and stepper motor production lines operate under strict quality control, with QC and production teams operating independently to eliminate conflict of interest. Every unit ships with full documentation: 3D CAD models, closed-loop stepper motor wiring diagrams, and NEMA 23/34 dimensional drawings -- available for immediate download at sefowmotor.com.
