Request Technical Data SheetShaanxi Nanfang Motor Technology Co., Ltd. is the authorized international distributor of Wolong Electric Drive Group Co., Ltd. Founded in 1984, Wolong was successfully listed in 2002 (code SH600580). Over decades of scientific development, Wolong has established 3 world-class manufacturing bases, 39 advanced factories, and 3 premier R&D centers globally.
As the primary export gateway to the United Arab Emirates and the wider GCC region, we supply high-performance, high-voltage explosion-proof machinery that meets the stringent requirements of ADNOC (Abu Dhabi National Oil Company) and UAE industrial standards. Our mission is to combine the technological heritage of century-old motor brands with modern, digital drive-control manufacturing capabilities.
Deploying heavy industrial machinery in the United Arab Emirates requires specialized design philosophies. The standard designs of standard industrial electric motors are insufficient for Middle Eastern operational profiles. The critical challenge in local operations stems from a combination of factors:
During peak summer seasons, outdoor ambient temperatures in Abu Dhabi's desert oil fields can reach up to 55°C. At the same time, solar radiation can heat metal frames even further. Consequently, standard high-voltage motors designed for 40°C suffer severe thermal output reductions. Our custom explosion-proof motors feature Class H insulation with Class B temperature rise configurations, ensuring they perform reliably without de-rating under extreme ambient conditions.
Sandstorms in dynamic desert areas introduce ultra-fine, abrasive silica dust that can damage bearings and wear down shaft seals. Additionally, coastal installations suffer from high humidity and air salinity. All our high-voltage motors supplied to the UAE feature specialized labyrinth seals, custom-engineered terminal boxes, and IP56/IP65 ratings to protect internal components from moisture and particulate ingress.
The UAE Ministry of Industry and Advanced Technology (MoIAT) enforces strict quality standards for explosion-proof installations. High-voltage motors must be certified to IECEx/ATEX standards and registered under the Emirates Conformity Assessment Scheme (ECASEx). Our motors are fully pre-certified, allowing for streamlined customs clearance and integration into critical ADNOC infrastructure.
By integrating historic global motor manufacturers, Wolong has consolidated advanced technologies to deliver high-quality, specialized machinery.
Austrian Heritage
Acquired in 2011, ATB is a leading European motor manufacturer with specialized designs for demanding industrial applications.
German Precision
Established in 1882, Schorch specializes in customized heavy-duty drives for oil, gas, and power generation systems.
UK Innovation
Over 110 years of experience designing premium, high-efficiency motors for harsh environments.
Specialized UK Engineering
Laurence Scott manufactures specialized, low-starting-current equipment for critical infrastructure and naval vessels.
Accumulating abundant assets and decades of experience in manufacturing, WOLONG has successfully expanded its global footprint. In 2011, WOLONG acquired 97.94% of the Austrian ATB Group (ATB motor), bringing together recognized brands like Morley and Laurence Scott under one roof. Morley motors carry nearly 130 years of underground industrial history, becoming synonymous with durability and safety, while Laurence Scott remains a key supplier of low-starting-current generators and specialized machinery.
In addition, Brook Crompton Motors and German engineering pioneer Schorch joined the Wolong Group, establishing a complete range of low, medium, and high-voltage AC motors designed to operate reliably in hazardous areas. In 2015, China’s largest explosion-proof research base, CNE (Nanyang Explosion-Proof Group), integrated into the company. Finally, in 2018, General Electric (GE)'s industrial motor division partnered with WOLONG, bringing deep expertise in heavy-duty machinery for oil, gas, refining, and mining projects.
A breakdown of our manufacturing processes, showcasing how Wolong motors achieve high safety ratings and operational efficiency.
The coils are constructed using high-grade polyester film reinforced with glass cloth and high-mica tapes. Following the VPI (Vacuum Pressure Impregnation) process, the windings achieve excellent insulation, high dielectric strength, moisture resistance, and reliable thermal stability.
Featuring cast aluminum and copper bar configurations, these rotors are produced using centrifugal casting or advanced die-casting methods. Integrally welded end rings and shaft-securing structures provide high torsional resistance, making them well-suited for high-vibration applications.
Engineered using multi-physics structural and fluid dynamics simulation platforms, our high-strength cast iron or fabricated steel frames provide robust heat dissipation and structural rigidity to withstand sudden mechanical loads.
Featuring air guides, protective windows, and internal sound-absorbing panels, the fan hood optimizes airflow paths. The side-inlet configuration reduces aerodynamic noise while maintaining an IP22/IP44 rating to protect the fan blade assembly.
Our explosion-proof high-voltage motors are certified by leading international testing houses, ensuring compliance with global and regional hazardous area regulations.

To support global exports and local integration in the UAE market, we maintain an extensive array of type test certifications, including:
As the UAE drives forward with its Net Zero 2050 strategic initiative and expands its industrial manufacturing capacity, the criteria for rotating equipment are shifting toward sustainability, smart connectivity, and high efficiency.
Integrating Ex-certified vibration, temperature, and current sensors directly onto the motor frame. This enables real-time diagnostic telemetry to flow back to SCADA systems, preventing unscheduled downtime in critical chemical and refining operations.
Transitioning traditional high-voltage induction designs to line-start permanent magnet (LSPM) synchronous systems. This technology significantly reduces electromagnetic rotor losses, cutting energy costs in high-duty water desalination and pipeline distribution networks.
