Shaanxi Nanfang Motor Technology Co., Ltd. is the premier authorized distributor of Wolong Electric Drive Group Co., Ltd.
Founded in 1984 and listed on the Shanghai Stock Exchange in 2002 (code SH600580), Wolong has advanced to become a powerhouse in global industrial motor manufacturing and control solutions. Under our comprehensive marketing and sales strategy, we integrate global manufacturing capacity with customized engineered solutions for energy-critical industries.
Over the past 30 years, Wolong has established 3 world-class R&D centers, 39 digital-twin manufacturing facilities, and 3 global manufacturing bases, building a strategic global R&D framework spanning China, Europe, and Japan. This network delivers leading-edge technologies designed to satisfy the world's most demanding industrial environments.
Industrial electric motor systems account for approximately 46% of global electricity consumption. Driven by international climate targets, stringent environmental regulations, and volatility in energy prices, the global manufacturing and processing sector is undergoing a rapid transition toward high-efficiency drive systems. Specifically, regulatory updates such as the European Union's Ecodesign Regulation (EU) 2019/1781 mandate minimum efficiency classes of IE3 and IE4 for industrial motors. In critical applications, the industry is already moving toward IE5 Ultra-Premium Efficiency classes, primarily powered by Permanent Magnet Synchronous Motors (PMSMs).
For operations involving heavy industrial components like high-voltage pumps, multi-megawatt fans, and coal conveyors, adopting high-efficiency motor drives yields direct savings in operational expenditures (OPEX) and supports corporate ESG mandates. These savings are achieved not only by upgrading standard low-voltage configurations but also by retrofitting large-scale, high-voltage explosion-proof machinery used in hazardous areas.
Simultaneously, industrial operators require high-reliability motors capable of surviving extreme mechanical stresses, voltage harmonics from Variable Frequency Drives (VFDs), and explosive atmospheres. Shaanxi Nanfang Motor meets these requirements by offering a comprehensive range of CE, ATEX, IECEx, and NEMA certified motors manufactured across Wolong’s global industrial footprint.
By acquiring several of the world's most respected electric motor manufacturers, Wolong has integrated a century of engineering experience into a single, global technology platform. This makes it a leading technical supplier for oil and gas, petrochemicals, power generation, and heavy mining industries.
Acquired in 2011, Austria’s ATB Group is a major European motor manufacturer. This brand includes Morley Motors, which brings nearly 130 years of history in underground coal mining equipment. Morley is recognized for manufacturing highly durable motors that deliver reliable performance in extreme mine-shaft environments.
Laurence Scott has supplied heavy-duty motors for nuclear power stations and low starting current generators for naval defense vessels. Brook Crompton, also part of the family, is a pioneer in high-efficiency designs, offering low, medium, and high voltage AC motors including the Brook Crompton "W" and "10" series.
Schorch (est. 1882) specializes in heavy-duty drive systems for petrochemical and tunnel ventilation systems. OLI is a global leader in industrial vibration technology, while CNE (Nanyang Explosion-proof Group) represents China’s largest research base for hazardous area motors. In 2018, the acquisition of GE Industrial Motors further expanded our capacity to support the oil, gas, and materials processing industries.
Purchasing electric motors from Chinese manufacturing bases offers significant advantages in lead times, manufacturing capacity, and pricing. China's integrated supply chains allow for rapid component sourcing, ranging from high-permeability electrical steel laminations and precision copper wire to cast-iron frames and specialized explosion-proof terminal boxes.
Our digital-twin production lines utilize automated stator winding machines, robotic insulation placement, and high-speed CNC lamination stamping tools. This manufacturing approach minimizes component tolerances and guarantees consistent electrical and mechanical performance across mass-production runs.
Furthermore, each manufacturing base features certified testing facilities where every motor undergoes routine testing. This includes winding resistance measurements, insulation testing, vibration analysis, and no-load tests to ensure full compliance with international standards prior to shipment.
A detailed breakdown of the advanced engineering, materials, and processes integrated into our electric motor components.
Our squirrel-cage rotors are built using centrifugal cast aluminum or high-pressure die-casting techniques. This process integrates the rotor bars and end rings into a single, high-durability assembly, minimizing internal electrical resistance and ensuring excellent starting torque. For larger, high-voltage motors, copper-bar rotors are utilized. These feature hand-welded rotor bars and end rings, secured with containment rings to withstand centrifugal stresses in high-speed and variable-frequency applications.
The stator windings are constructed using polyester-film-reinforced magnetic wire combined with mica-rich insulation tape. Once wound, the stator core undergoes a computerized Vacuum Pressure Impregnation (VPI) cycle with high-grade resins. This eliminates air pockets and moisture, creating a solid insulation structure with excellent heat dissipation, mechanical strength, and resistance to environmental moisture, thermal cycles, and voltage surges from variable frequency drives.
Designed using multi-physics structural and thermal simulations, our motor frames are cast from high-tensile gray iron or welded structural steel plates. This structural design provides high rigidity, low vibration levels, and efficient heat transfer. Optimized external cooling fins, combined with calculated thermal mass distribution, ensure even cooling, which helps extend bearing life and insulation longevity.
The low-noise ventilation system consists of an engineered fan shroud, air guide cylinders, protective mesh screens, and sound-absorbing lining. Its side-intake design minimizes the aerodynamic turbulence often caused by nearby walls or structures. With dynamic fan balancing and optimized shroud geometry, this system significantly reduces noise levels while maintaining high cooling airflow. It carries an ingress protection rating of IP22, preventing accidental contact with rotating parts.
Operating in hazardous, industrial, and heavy marine environments requires compliance with international safety and quality standards. Our motors carry certifications from major global testing laboratories, ensuring trouble-free installation and operation worldwide.

Through 39 specialized production facilities and 4 global R&D centers, our manufacturing system coordinates engineering designs to support operations in diverse industrial markets.
CE-certified motors from our factories comply with the European Union's safety, health, and environmental protection requirements. This certification ensures standard compatibility with European industrial installations. Additionally, our global manufacturing network enables cost-efficient production, high quality control, and shorter delivery lead times for specialized low, medium, and high voltage motors.
ATEX is a European directive mandated for equipment installed within the EU hazardous areas. IECEx is an international certification scheme recognized globally. Many of our high-voltage and low-voltage explosion-proof motors (such as the Wolong ATB and Nanyang brands) carry dual certification, allowing them to meet regional safety standards worldwide.
The VPI process extracts air and moisture from the stator core, filling the void spaces with protective resin. This reinforces the winding insulation, improves thermal heat dissipation, and prevents mechanical failures caused by vibration, chemical contaminants, or electrical stress from variable frequency drive operation.
Yes, we design and manufacture three-phase asynchronous motors compliant with NEMA standards (such as our NSHE series), carrying both UL and CSA certifications for North American industrial applications.
Water-cooled motors (such as the YBBP water-cooled series) are suitable for environments with restricted airflow, high ambient temperatures, or strict noise limits. By routing heat out of the motor housing via cooling water jackets, they maintain low operating temperatures and compact profiles, making them popular in mining, chemical processing, and marine applications.
