Sweg Motor
Nagoya, the heart of the Chubu region, stands as Japan's unrivaled industrial capital. Known globally for the "Nagoya Protocol" and as the home base for automotive titans like Toyota, the city represents a unique intersection of mechanical heritage and futuristic automation. In this high-stakes environment, Shunt Wound DC Motors have become the silent workhorses of precision manufacturing. Unlike series-wound motors, shunt motors offer the "self-regulating" speed characteristic essential for conveyors, printing presses, and industrial lathes that dominate the Nagoya production landscape.
As a leading exporter in Nagoya, we understand that global procurement teams are no longer just looking for a component; they are looking for a "Total Motion Solution." Our shunt-wound technology provides exceptional speed regulation, allowing for constant RPM even under varying loads. This is critical for the "Just-In-Time" (JIT) manufacturing processes pioneered in the Greater Nagoya area and now exported to factories worldwide.
The future of DC motors in industrial applications is defined by Energy Efficiency (IE3/IE4 standards) and Smart Integration. Our technical roadmap for Nagoya-based projects includes:
Zhejiang Sweg Motor Co., Ltd. is a professional manufacturer specializing in the research, development, production, and sales of electric motors, gear motors, and transmission solutions. With years of industry expertise and continuous technological innovation, Sweg Motor has established itself as a reliable partner for customers worldwide.
Our company operates modern production facilities covering more than 10,000 square meters, equipped with advanced automated manufacturing lines for stamping, winding, assembly, testing, and quality control. Supported by an experienced engineering team and strict production management, our annual production capacity reaches millions of motor units, enabling us to meet diverse customer requirements efficiently.
Quality is at the core of everything we do. Our company has successfully obtained ISO 9001 Quality Management System Certification, ensuring that every product is manufactured according to international quality standards. In addition, many of our products comply with global certification requirements, including CCC, CE, CB, VDE, RoHS, and other market-specific standards.











The global demand for high-torque DC motors is surging, driven by the automation of warehouse logistics (AMRs), renewable energy trackers, and specialized medical equipment. As a Nagoya-centric exporter, we provide localized support that bridges the gap between Eastern manufacturing efficiency and Western compliance standards.
Our Macro-Industrial Applications:
We ensure local compliance for every region, including UL (North America), CE (Europe), and PSE (Japan), ensuring that your import process is seamless and legally secure.
Shunt motors are prized for their ability to maintain constant speed regardless of load changes. This makes them ideal for industrial equipment where precision and uniformity are required, such as in CNC machines or automated assembly lines in Nagoya factories.
Yes. We provide deep customization for shaft dimensions, voltage requirements, and protection ratings (up to IP67). We ensure all exports meet the specific safety and efficiency standards of the destination country, including Japanese JIS standards.
Every motor undergoes a multi-stage testing process, including dynamic balance tests, insulation resistance checks, and noise level analysis. Our ISO 9001 certified facility uses automated winding and assembly to eliminate human error.
Standard orders typically have a lead time of 15-30 days. For large-scale industrial projects, we provide a detailed production schedule and logistics support to ensure on-time delivery to global ports.
Your Success, Our Commitment.
