Founded in 1998, Zhejiang Rilvo Automation Equipment Co., Ltd. is a high-tech equipment manufacturer integrating scientific research, product design, precision tooling, assembly, and worldwide technical support. We specialize in automated equipment for electric motor stators, armatures, field coils, micro-motors, and clean-energy vehicle drivetrains.
Our manufacturing headquarters is situated in the Shatianyang Development Zone, Sanmen, Taizhou, Zhejiang Province, occupying nearly 60,000 square meters of dedicated industrial park. With more than 20,000 m² of modern heavy-assembly facilities and an additional 30,000 m² under progressive expansion, we maintain full control over mechanical tolerance, heat treatment, software integration, and final quality validation.
As an ISO9001:2015 certified manufacturer and recipient of China Compulsory Certification (3C), Rilvo combines over 27 years of applied engineering experience with 17 national patents, serving motor manufacturers across Europe, Southeast Asia, South America, and the Middle East.
We solve cycle-time bottlenecks, wire insulation scuffing, and dimensional variation across every critical step of motor production.
Engineered for high-slot-fill stators, automotive alternators, starter motors, and appliance motors with uniform slot paper insertion and gentle wire manipulation.
High-precision rotor winding and commutator fusion designed for starter motors, power tools, automotive actuators, and low-voltage traction armatures.
Turnkey motor production and secondary process automation configured around your daily target volume and plant floor footprint.
Our progression from specialized tooling manufacturer to global automation provider.
Established in Zhejiang to deliver high-precision tooling and specialized fixtures for domestic electric motor and starter component builders.
Commercialized proprietary multi-axis servo winding controllers and automated wire inserting systems, reducing changeover cycles by 60%.
Relocated to the 60,000 m² industrial park in Sanmen, recognized as a Provincial High and New Technology Enterprise, and crossed 15 national patents.
Exporting to over 30 countries with full OEM/ODM capabilities, providing custom tooling for new-energy EV motors, starter stators, and BLDC applications.
To eliminate reliance on external subcontractors and maintain strict dimensional accuracy, Zhejiang Rilvo Automation Equipment Co., Ltd. operates more than 150 metal-cutting, CNC milling, wire-EDM, and surface-grinding machines in-house. This ensures all tooling, winding flyers, and insertion fingers meet rigorous metallurgical and dimensional standards.
