Explore our premier configurations designed for German industrial safety standards, marine decarbonization, and extreme industrial environment resilience.
As Europe's economic powerhouse, Germany enforces some of the world's most stringent environmental and energy efficiency regulations. Under the EU Ecodesign Regulation (EU) 2019/1781, industrial motors operating within the German market must comply with escalating minimum efficiency standards (IE3 and IE4). For specialized and custom applications, classified under our "Other Series Motor" category, integration with high-efficiency variable-frequency systems is critical.
Our solutions target key German manufacturing hubs. From chemical parks in Ludwigshafen and the heavy metal industries in the Ruhr area, to the sophisticated maritime sectors navigating northern waterways and southern Alpine lakes, our tailored electric motors meet exact localized requirements. Specifically, Germany's strict ATEX explosion-proof requirements and the marine transition toward sustainable zero-emission waterways drive the design and distribution of our specialized marine and industrial drive trains.
The global powerhouse for industrial electric drives and international system distributions.
Shaanxi Nanfang Motor Technology Co., Ltd serves as the authorized distributor of Wolong Electric Drive Group Co., Ltd. Wolong, established in 1984 and listed on the Shanghai Stock Exchange in 2002 (code SH600580), has grown over three decades into a leading global provider of motors and drive control systems.
Today, Wolong operates 3 primary manufacturing bases, 39 individual production factories, and 3 global R&D centers. Wolong's international growth strategy focuses on high-end manufacturing, continuous innovation, and local market customization. This approach guarantees that clients in highly regulated industrial zones, such as Germany, receive motor systems that comply with all CE, ATEX, IECEx, and DIN standards.
How Wolong brought together the century-old heritage of European and global motor technology.
WOLONG acquired 97.94% of the Austrian ATB Group (ATB Motor), a leading European motor manufacturer. This acquisition brought specialized mining, oil, gas, and power engineering technology into the Wolong system. The purchase also integrated renowned brands like Morley and Laurence Scott into the group.
Adding over a century of electric motor design expertise, Brook Crompton joined the group, introducing its energy-efficient "W" and "10" low-to-high voltage AC motor series. Simultaneously, Schorch, established in Germany in 1882, brought its specialized experience in supplying high-quality drive systems to German and European petrochemical, power generation, and steel processing industries.
In 2015, Wolong integrated CNE (China's Nanyang Explosion-proof Group), establishing a strong base for Ex-proof machinery. In 2018, Wolong partnered with General Electric's industrial motor business. This partnership expanded the group's capabilities in heavy industrial sectors, including mining, material processing, and large-scale water treatment systems.
Aligning with safety, efficiency, and customized engineering standards.
Our motors carry dual-certified international explosion-proof marks, allowing seamless installation in hazardous zone 1, zone 2, zone 21, and zone 22 throughout EU industries.
Offering options up to IE5 efficiency, our permanent magnet synchronous motors (PMSM) help German enterprises lower overall energy costs and reduce carbon footprints.
Our "Other Series" covers specialized environments, from sub-zero tunnel boring setups to offshore marine propulsion, providing reliable torque under extreme mechanical stress.
A technical look at the materials, safety configurations, and structural design of our motor systems.
Our rotors feature a robust squirrel-cage design, utilizing high-pressure cast aluminum or centrifugal copper casting. The raw aluminum is poured directly into the rotor core slots to form integrated end rings and bars. For high-capacity, high-speed machines, copper bar designs are welded with specialized alloy methods, supported by high-strength protective rings. This design keeps vibration within tight parameters, meeting DIN ISO 20816 standards.
The stator coil is wound with premium polyester film and glass cloth-backed mica tapes. Using the Vacuum Pressure Impregnation (VPI) process, the entire winding is cured with high-grade solventless epoxy resin. This creates a solid, moisture-resistant, and chemically inert insulation barrier. This setup provides excellent dielectric strength and thermal properties, maintaining reliable Class H or Class F insulation ratings.
Using digital multi-physics simulation platforms, we optimize the frame's heat dissipation and structural strength. Built from high-tensile cast iron or welded structural steel, the frame absorbs mechanical shocks and isolates system resonances. This structural rigidity helps extend bearing life and ensures stable operation in harsh environments.
The low-noise ventilation cover features an aerodynamic guide cylinder, safety screens, and internal silencer plates. By placing the air inlet on the side, we reduce aerodynamic losses, minimizing fan noise while maintaining high cooling rates. This configuration meets IP22 or IP55 ingress standards, keeping the motor within optimal operating temperatures.
Meeting requirements for major international and European testing houses.
Adapting to Industry 4.0, smart diagnostics, and high-efficiency designs.
Industrial motors are key targets for energy savings, as drive systems account for nearly two-thirds of industrial electricity consumption. The transition to higher efficiency levels remains a major trend in the German market, driven by rising energy costs and strict carbon accounting requirements. In response, our technology roadmap focuses on three main developments:
Explore our full line of specialized asynchronous, synchronous, explosion-proof, and custom drive systems.
Answers to common technical and logistical questions regarding motor distribution in Germany.
Our motors are designed and tested to comply with EU Ecodesign Regulation (EU) 2019/1781. We offer high-efficiency three-phase asynchronous motors that meet IE3 and IE4 standards, along with permanent magnet synchronous motors (PMSM) that reach IE5 performance levels. These units are CE marked and come with full efficiency documentation for European installations.
Yes, all our explosion-proof models (such as the YFB3, YBX3, and YBSS series) hold ATEX and IECEx certifications. They are fully certified for installation in hazardous gas (Zone 1, Zone 2) and dust (Zone 21, Zone 22) environments, complying with European standard EN 60079.
As the authorized distributor, and with ATB and Schorch operating as part of the Wolong Group, we supply direct replacement motors that match the mounting footprints, shaft heights, and performance parameters of older European installations. This simplifies the process of upgrading to higher-efficiency systems without requiring extensive base changes.
Typical lead times range from 8 to 12 weeks for standard models, and 16 to 20 weeks for large high-voltage systems requiring custom shaft designs, non-standard mounting configurations, or specialized sensor integrations. Shipping transit times from our manufacturing facilities to major German ports are fully optimized through established freight channels.
