Engineered to withstand the most demanding operational environments, our heavy industrial solutions incorporate ATEX, IECEx, and NEMA certifications for global compatibility.
Shaanxi Nanfang Motor Technology Co, Ltd is the authorized distributor of Wolong. Wolong Electric Drive Group Co., Ltd was founded in 1984 and successfully listed on the Shanghai Stock Exchange in 2002 (code SH600580). Over the past three decades, Wolong has solidified its market presence globally. Today, the corporation operates 3 strategic manufacturing bases, 39 manufacturing factories, and 3 high-tech R&D centers worldwide. Wolong focuses comprehensively on the manufacture of advanced motors and drive control systems, striving to deliver high reliability, safety, and operational excellence to global industrial buyers.
By integrating the heavy duty product catalog and industrial assets from the world's most renowned classic drive technologies, Wolong has consolidated global powerhouses under its banner: Brook Crompton, Morley, Laurence Scott, Schorch, ATB, OLI, and the industrial motor division of General Electric (GE Industrial Motors). This makes Shaanxi Nanfang Motor Technology Co., Ltd a premier gateway for procurement, technical coordination, and customization of premium OEM electrical powertrains.
Combining heavy-duty machinery design parameters with standard and hazardous-area certifications to keep critical processes running smoothly.
Robust protection topologies designed for environments filled with volatile gases, dust, or moisture. Multiple certifications (ATEX, IECEx, CSA, Nemko, SABS, and TESTSAFE) ensure local compliance globally.
Designed with low rotor losses, high-density stator copper fill factors, and permanent magnet synchronous motors (PMSM) to ensure lower carbon footprints and minimal lifecycle operating expenses.
Comprehensive array of low voltage, medium voltage, and high voltage asynchronous and synchronous machinery, tailored specifically to integrate with fans, pumps, compressors, and conveyors.
Industrial operations dictate a continuous search for energy efficiency, mechanical durability, and strict regulatory adherence. For decades, the General Electric (GE) industrial motor lineup stood at the core of massive mining, water processing, power, and oil & gas projects. In 2018, the strategic integration of GE's commercial and industrial motor division into the Wolong Electric Drive Group created an engineering synergy that combined GE's robust NEMA design methodologies with Wolong's highly modernized production platforms. Shaanxi Nanfang Motor Technology Co., Ltd. serves as a vital engineering distributor within this network, bridging the gap between custom requirements and massive production facilities.
The acquisition of GE's commercial and industrial motor business by Wolong in 2018 consolidated more than a century of American design expertise with a agile manufacturing engine. The transition preserved all patented technologies, manufacturing specifications, and product standards such as the Energy $aver® and Quantum® motor lines. Today, these motors are distributed globally to handle tough applications under extreme temperatures, heavy structural shock loads, and toxic environments. This industrial consolidation has empowered Wolong to construct a global industrial network spanning North America, Europe, and the Asia-Pacific, maintaining localized technical support while reducing lead times through global factory networks.
Wolong's acquisition strategy has established a massive array of recognized industry brands, including:
Procuring custom electrical machinery involves balancing cost, lead times, and quality control. By leveraging the Wolong Nanyang manufacturing facility, our production lines achieve unmatched efficiency. The implementation of digital twin design methodologies, multi-physics finite element analysis (FEA), automated coil winding, and advanced Vacuum Pressure Impregnation (VPI) guarantees high dielectric strength and heat dissipation. The centralization of key component casting, high-grade silicon steel sheet punching, dynamic rotor balancing, and full-load motor testing reduces production bottlenecks, allowing our team to complete complex projects on time.
Empowered by global engineering networks, world-class testing facilities, and century-old structural patents.
Collaborative motor and drive control R&D centers located in China, Europe, and Japan, with a central research institute in Shanghai. Our research pushes boundaries, introducing technologies that match or exceed IEEE, IEC, and NEMA premium standards.
Direct access to Nanyang Explosion, Brook Crompton, Morley, Laurence Scott, Schorch, and ATB, ensuring seamless component sourcing, drop-in dimension replacements, and specialized engineering support.
Decades of leadership in Ex design. Our explosion-proof low and high-voltage motors operate safely in hazardous gas and combustible dust zones globally, holding ATEX, IECEx, CSA, CU-TR/EAC, and TestSafe certifications.
We perform exhaustive dynamic testing (vibration, load efficiency, thermal rise, and insulation barrier integrity) to satisfy international regulatory frameworks.

Adhering to a comprehensive marketing strategy for electric motors and their supply chains, Wolong has secured critical international certifications:
A deep look into the structural details that enable our custom electric motors to outlast standard industrial options.
The rotor features a squirrel cage configuration, utilizing cast aluminum built through centrifugal casting or high-pressure die-casting. This process embeds pure aluminum into the rotor core slots, integrating the rotor bars and end rings into a solid, unified piece. This structural approach guarantees reliable start-stop cycles and high operating torque.
For high-capacity, high-torque configurations, copper bar rotors are utilized. By employing copper bar securing techniques and precise end ring welding, we prevent bar movement and rotor fatigue. High-speed models also incorporate retaining protective rings, ensuring reliable operation under centrifugal stress.
Coils are constructed from premium polyester-imide enameled wire, insulated with polyester film and reinforced glass cloth. Our insulation system uses low-powder mica tape with high mica content or medium-powdered mica tape, ensuring stable dielectric performance under high-voltage stresses.
Once wound, the entire stator core undergoes Vacuum Pressure Impregnation (VPI), curing the resin into a moisture-resistant structure. This process fills air gaps, eliminating partial discharge and enhancing thermal dissipation, mechanical strength, and chemical resistance.
Motor frames are designed using multi-physics structural and fluid thermal digital simulations. This platform preserves structural patents while utilizing high-tensile cast iron (or structural steel plate as needed). Our frames are engineered with high safety margins, isolating operating frequencies to prevent resonance and handle mechanical shocks, resulting in lower vibration and lower temperature rises.
The low-noise ventilation system integrates a balanced fan cover, air guide cylinder, protective mesh, and sound-dampening baffles. Its compact design reduces aerodynamic turbulence. By utilizing a side-entry air inlet design, the flow path avoids obstructions, reducing noise generated by sudden air deflection.
Sound-absorbing linings are applied to reduce mid-to-high frequency fan noise, achieving lower dBA ratings. The fan cover meets an IP22 safety rating, preventing accidental contact with rotating parts.
The industrial sector consumes over 40% of global electricity, and electric motor-driven systems account for nearly two-thirds of that consumption. Consequently, upgrading to premium efficiency motors is a key path toward corporate cost control. As environmental regulations tighten, industries are shifting from legacy standard efficiency motors to IE4 and IE5 technologies. Heavy duty fields—such as oil refineries, petrochemical plants, deep coal mining operations, and public water treatment grids—demand drive equipment that offers both high energy efficiency and durability in harsh conditions.
Heavy duty motors are rarely standard off-the-shelf items. They must be customized to meet localized operational requirements:
Global procurement teams must look beyond initial acquisition costs. Operational evaluation focuses on three key metrics:
From deep mining operations to marine systems, our drive technologies deliver reliable performance across diverse sectors.
