Shaanxi Nanfang Motor Techmology Co, Ltd is the authorized distributor of Wolong. Wolong Electric Drive Group Co., Ltd was founded in 1984 and successfully listed in 2002 (code SH600580).
After more than 30 years of rapid global expansion, Wolong currently coordinates 3 core manufacturing bases, 39 manufacturing factories, and 3 localized R&D centers worldwide. Focused intensely on advanced motor design and complete control systems, Wolong executes a worldwide unified brand strategy, leading in R&D, processing technology, high-end fabrication, and market networks.
Learn More About Nanfang MotorGOST (Gosudarstvenny Standart) remains the absolute blueprint for technical and safety compliance across the CIS (Commonwealth of Independent States) region. When deployment takes place in hazardous and cold-climate zones, standard international motors (IEC or NEMA) without mechanical, electrical, and thermal adaptations fail to comply with regulations or operate reliably under local infrastructure constraints.
As an industry-leading OEM GOST Standard Electric Motor manufacturer and exporter, Shaanxi Nanfang Motor Techmology Co, Ltd (via the Wolong platform) designs motors certified for local regulations, covering crucial standards such as GOST 31606 (asynchronous general industrial motors), GOST IEC 60079 (explosion-proof equipment), and EAC declaration directives.
Our heavy-duty GOST-compliant electric motors are developed for continuous operation in the resource-extraction fields of Central Asia and Northern climates. They handle extreme ambient temperature fluctuations ranging from -60°C to +40°C (execution types UHL1, UHL2, and UHL4). Key industries served include:
Exporting to CIS markets requires more than a GOST plate. We provide comprehensive localization documentation:
We supply multi-certified motors that clear strict regulatory hurdles globally. Whether you need EAC certification for CIS countries, ATEX/IECEx for European projects, or UL/CSA for NEMA standards, we have you covered.
Our technology meets and exceeds modern energy standards. We offer dynamic solutions across IE3, IE4, and ultra-high-efficiency IE5 levels, with synchronous permanent magnet options for advanced energy-saving profiles.
A broad array of low, medium, and high-voltage AC motors designed to survive the harshest environments, including marine, metallurgical, and highly volatile gaseous installations.
Wolong has established advanced motor and drive control R&D centers in China, Europe, and Japan, alongside its central research institute in Shanghai. By focusing on multi-physics simulation, noise reduction, and smart controls, our products compete at the leading edge of global electrical engineering.
Through selective acquisition and strategic partnerships, Wolong integrates legendary century-old motor brands: Brook Crompton, Morley, Laurence Scott, Schorch, ATB, OLI, and GE Industrial Motors. This structural synergy allows us to deploy high-spec customized electrical equipment anywhere on earth.
The rotor features a rugged squirrel cage design, utilizing cast aluminum structures engineered through centrifugal aluminum casting or precision high-pressure die-casting. The molten pure aluminum fills the rotor core slots to form integrated rotor bars and end rings, delivering outstanding starting torque and structural durability.
For large-capacity high-voltage motors, copper bar rotors are utilized. Reliable bar-securing processes and automated end-ring welding ensure mechanical stability under extreme rotational stress. High-speed models are equipped with robust retention ring designs to maintain copper bar alignment.
The stator coil is built with high-grade polyester film reinforced with glass cloth, using low-powder mica tape or premium medium-powdered mica tape. After precision winding, the stator core undergoes a full Vacuum Pressure Impregnation (VPI) cycle, creating a solid, well-insulated structure.
This insulation process ensures high electrical and mechanical strength, moisture resistance, and thermal stability in compliance with Class F (155°C) and Class H (180°C) standards.
Our motor frames are optimized using digital structural and fluid multi-physics field simulations to maximize thermal dissipation and mechanical rigidity. Built from high-strength cast iron (or structural steel for custom configurations), the frame design incorporates significant structural margin to withstand physical shock and isolate external vibrations. This results in stable operation, lower temperature rise, and extended bearing life in the field.
The fan cover system comprises a lightweight fan cover body, air guide cylinder, protective window, and integrated silencer plate. The side-entry air inlet design optimizes airflow pathways and minimizes turbulence behind the motor.
Sound-absorbing materials within the path absorb high-frequency noise, reducing overall acoustic output. Additionally, the system carries an IP22 rating, preventing accidental contact with the fan.
To establish a world-class position in the industrial drive market, Wolong has continuously acquired and integrated leading international motor manufacturers. This consolidation has brought together centuries of expertise under a unified supply chain:
In 2011, Wolong acquired a 97.94% stake in the Austrian ATB Group. This added specialized brands like Morley—with 130 years of underground coal mining experience—and Laurence Scott, renowned for low-starting-current designs and nuclear power auxiliary motors, to the portfolio.
Germany's Schorch, established in 1882, brought high-voltage expertise for oil, gas, and chemical processing projects. Concurrently, the addition of Brook Crompton expanded our offerings with their energy-efficient "W" and "10" low-voltage motor series.
Since partnering with OLI in 1999, Wolong has expanded its offerings in industrial vibration and material handling technologies globally.
In 2015, Nanyang Explosion Protection Group Co., Ltd. (CNE) joined Wolong, strengthening our capacity to manufacture heavy flameproof and high-voltage motors. The subsequent integration of GE's commercial and industrial motor division in 2018 completed our industrial drive portfolio.
