Explore our signature series of low and high-voltage three-phase asynchronous motors engineered for standard and hazardous environments.
The global transition towards industrial automation, coupled with strict decarbonization and green targets, has shifted electric motor preferences toward lightweight, thermally efficient solutions. Cast aluminum electric motors represent a critical evolution in material science for machinery manufacturing. Compared to traditional heavy cast iron structures, cast aluminum alloys offer superior thermal conductivity, higher power-to-weight ratios, and excellent corrosion resistance.
Today, industries ranging from HVAC and marine engineering to electric mobility and clean water infrastructure demand motors that minimize mechanical footprints while maximizing electrical efficiency (IE3, IE4, and IE5 standards). Driven by these modern energy metrics, global industrial buyers actively seek qualified OEM partners capable of producing customizable, safety-certified aluminum-housed drivetrains.
Shaanxi Nanfang Motor Technology Co., Ltd. serves as the premier authorized distributor of Wolong Electric Drive Group Co., Ltd., presenting a unified front of century-old industrial heritage and massive scale.
Founded in 1984 and listed on the Shanghai Stock Exchange in 2002 (code SH600580), Wolong has spent over 30 years scaling its operations. Today, the corporation features 3 global manufacturing bases, 39 manufacturing factories, and 3 state-of-the-art R&D centers worldwide. Wolong is committed to a global brand strategy, making it a primary leader in motor design and control systems.
In 2011, Wolong acquired 97.94% of the Austrian ATB Group, one of the three major European motor manufacturers. This acquisition integrated renowned industrial brands such as Morley (underground mining specialists with 130 years of history) and Laurence Scott (renowned for British nuclear facility powertrains and naval marine generators).
By bringing Germany's Schorch (est. 1882) and the UK's Brook Crompton Motors (over a century of design mastery) into its brand umbrella, Wolong has solidified its low, medium, and high-voltage industrial motor capabilities across hazardous locations worldwide.
To capture specialized markets, Wolong established a partnership with OLI Vibration Motor in 1999, achieving the largest market share globally for vibration motors and Ex-proof vibration sensors. In 2015, China’s largest explosion-proof scientific research and production center, CNE (Nanyang Explosion-Proof Group Co., Ltd.), officially joined the Wolong Group, enabling premium access to oil, coal, petrochemical, nuclear, and military supply chains.
Further extending its international footings, General Electric (GE) Industrial Motors joined the Wolong network in 2018. Combining GE’s extensive commercial and heavy-industry experience with Wolong’s high-capacity manufacturing structures, the group delivers high-performance electric powertrains that withstand the harshest processing environments globally.
How our certified systems protect your production lines, reduce lifecycle energy expenses, and streamline supply chains.
We provide full explosion-proof, flameproof, and non-sparking certifications (including Nemko/ATEX, CSA, CE, SABS, and TESTSAFE standards). Our designs ensure risk-free operations in Zone 1, Zone 2, Zone 21, and Zone 22 environments.
We actively manufacture systems aligning with international IE3, IE4, and ultra-premium IE5 energy efficiency directives. Permanent magnet synchronous options (WEPM series) are integrated with frequency control to optimize power consumption.
Through motor and drive R&D centers in China, Europe, and Japan, alongside our Central Research Institute in Shanghai, we provide tailor-made shaft, frame, mounting, and voltage variations tailored to local industrial specifications.
Every component is engineered to maximize thermal heat dissipation, structural longevity, and mechanical balance.
Featuring a squirrel cage profile manufactured via centrifugal aluminum casting or die-casting. Molten pure aluminum is injected into the rotor core slots to construct a single-piece component. This process minimizes air pocket voids, increases torque transmission efficiency, and balances rotational stability.
Crafted from premium polyester film reinforced with high-mica content glass cloth tapes. Our stators undergo VPI (Vacuum Pressure Impregnation) treatments to form a solid, moisture-resistant protective block. This achieves excellent dielectric properties, structural tightness, and thermal stability under long-term continuous loads.
Simulated using digital platforms for structural and fluid multi-physics fields. Built from cast aluminum (or robust steel/cast iron alternatives) with extended surface fins. The chassis maximizes heat dissipation while incorporating native frequency isolation margins to absorb vibration and withstand mechanical shocks.
Features a dynamic fan cover body, air guide cylinder, protective mesh window, and acoustic silencer lining. An optimized side air inlet protects against obstruction, reduces acoustic noise from aerodynamic turbulence, and holds an IP22 rating to prevent direct contact with rotating blades.
How our localized integration and state-of-the-art production centers solve lead-time, quality, and cost constraints for international buyers.
China is the global center for high-pressure die-casting and precision electric motor manufacturing. By basing our primary casting and winding operations in highly integrated industrial zones, Shaanxi Nanfang Motor and Wolong capitalize on localized metal supply chains, advanced robotic tooling, and highly skilled manufacturing engineering teams.
This structural efficiency translates to faster prototype iterations, lower tooling costs for custom OEM projects, and competitive lead times compared to domestic western manufacturers.
Wolong's diverse range of motor solutions provides reliable traction and power across numerous global industries.
In refineries and transport systems, our flameproof (YBSS, YBX3, YBX5 series) and non-sparking (YWKK, YWKS series) high-voltage motors operate pumps, gas compressors, and ventilation fans. These systems prevent volatile hydrocarbon ignition in Zone 1/2 environments.
Heavy duty mining machines, underground conveyors, and tunnel boring drills require high startup torques and rugged dust resilience. Our specialized Morley brand motors and Wolong YBU/YBUS/YBUD series are built to survive coal dust, vibration, and moisture.
For vessel auxiliary operations and electric propulsion, we supply low-voltage marine motors (such as the YQ Series) that feature DNV Type Approval certificates. These motors resist salt mist corrosion and meet structural marine requirements.
Meeting the compliance, logistics, and quality demands of global procurement offices.
To clear global barriers, Wolong maintains fully certified ISO 9001 quality management systems. Our processes are designed to meet standard manufacturing safety requirements, offering consistent quality for large procurement batches.
For North American clients, we supply low and medium-voltage three-phase motors compliant with NEMA standard frames (such as the NSHE and NEXP series), which carry certified UL and CSA approvals.
For the European Union, we supply certified explosion-proof products. This streamlines system integration for global engineering firms managing complex installations.
Essential engineering insights to assist procurement teams in choosing the correct motors for demanding industrial projects.
