Shaanxi Nanfang Motor Technology Co., Ltd. is the authorized distributor of Wolong Electric Drive Group Co., Ltd. Wolong was founded in 1984 and listed on the Shanghai Stock Exchange in 2002 (code SH600580). With over 30 years of rapid expansion, Wolong operates 3 manufacturing bases, 39 factories, and 3 global R&D centers.
Our alliance guarantees heavy industrial operators direct access to an elite engineering ecosystem. Wolong continues to champion a global brand strategy, leading in R&D, process technology, customized manufacturing, and technical sales across Europe, the Americas, and APAC.
Explore Industrial CapabilityTechnological shifts, decarbonization targets, and stricter regulatory frameworks are redefining safety and efficiency standards in modern industrial environments.
Global energy policies require industrial motors to operate with minimal losses. The market is shifting from IE3 toward IE4 and IE5 permanent magnet synchronous designs, reducing carbon footprints in high-duty operations.
Predictive maintenance is essential in hazardous locations. Motors now include Ex-certified vibration sensors and thermal monitoring, allowing real-time analytics without risking explosive dust or gas ignition.
The rise of hydrogen as a clean energy carrier requires motors to meet strict Group IIC flameproof standards. Stator and frame designs are engineered to prevent flame propagation in hydrogen-rich atmospheres.
Through strategic acquisitions and technology integration, Wolong has unified several century-old motor brands under a single, cohesive industrial banner.
Wolong acquired a 97.94% stake in the Austrian ATB Group, integrating brands like Morley and Laurence Scott. This expansion introduced low-starting-current naval generators and specialized underground mining drives into the product lineup.
Morley brings nearly 130 years of underground coal mining expertise, producing high-specification flameproof drives. Laurence Scott has supplied safety-critical motors to nuclear power installations for generations, earning three consecutive Queen's Awards for technical excellence.
The addition of Brook Crompton and Schorch expanded Wolong's reach in energy-efficient designs. These motors supply reliable power to oil, gas, chemical processing, maritime, and steel processing industries globally.
In 2015, CNE (Nanyang Explosion-Proof Group) joined the Wolong Group, combining explosion-proof R&D with global manufacturing. In 2018, GE's commercial and industrial motor division joined, adding heavy-industry support across global markets.
Certified drive solutions for Group I, Group II, and Group III hazards, covering Zone 1, 2, 21, and 22 classifications worldwide.
A complete lineup of IE3, IE4, and IE5 permanent magnet synchronous motors, optimizing power usage and system performance.
Versatile motor solutions ranging from low-voltage drives to high-voltage, non-sparking, and flameproof machines for heavy industrial use.
Our hazardous area motors are engineered with advanced materials and structural modeling to withstand extreme mechanical stress and prevent electrical ignition.
Our stator windings use polyester film backed with glass cloth and high-mica tapes. Following the VPI (Vacuum Pressure Impregnation) process, the coils are thoroughly sealed. This provides high electrical strength, mechanical rigidity, moisture resistance, and thermal stability in hot, damp, and volatile environments.
We supply cast-aluminum squirrel cage rotors made via centrifugal casting or die-casting to integrate the rotor bars and end rings. For large-capacity drives, copper bar rotors are used with high-strength welding. Dynamic balancing prevents localized friction, hot spots, and shaft currents.
Using digital multi-physics thermal and structural simulations, our motor frames are cast from high-grade iron or structural steel. This design handles external impact hazards, improves thermal dissipation, and reduces vibration to prevent structural failures.
Featuring a side-mounted air intake, an air guide cylinder, and silencer plates, our IP22 fan cover minimizes noise and prevents ventilation blockages. Built with sound-dampening materials, it reduces sound pressure levels without restricting cooling air flow.
Our products are tested and certified to comply with international safety regulations, helping operators meet regional environmental and performance requirements.

Wolong's motor solutions are deployed across a range of heavy industrial sectors, driving pumps, compressors, high-volume fans, and complex process machinery. Our systems are engineered to perform reliably in demanding environments, including:
As modern industries evolve, our R&D roadmap focuses on developing safer, more efficient, and connected drive technologies.
We are expanding our range of IE5 Ultra-Premium efficiency motors across low and medium voltages, helping operators reduce grid energy losses and lower operational carbon footprints.
We are developing pre-engineered variable frequency drive (VFD) packages matched to explosion-proof motors. This helps reduce installation time, eliminate harmonic losses, and simplify commissioning.
Integrating real-time thermal, vibration, and magnetic flux sensors with edge computing systems allows operators to monitor motor health remotely and predict maintenance needs before failures occur.
