High-efficiency, variable frequency, and flameproof induction motors tailored for international heavy industries.
Shaanxi Nanfang Motor Technology Co., Ltd serves as the premier authorized distributor for Wolong Electric Drive Group Co., Ltd. Founded in 1984 and listed on the Shanghai Stock Exchange in 2002 (code: SH600580), Wolong has evolved into an undisputed global leader in the manufacture of electric motors, generator systems, and drive control solutions.
Over the course of three decades of aggressive strategic expansion, technology acquisition, and engineering refinement, Wolong has unified some of the world's most revered industrial electric motor brands under its banner. In 2018, General Electric's (GE) industrial motor business integrated into the group, joining the ranks of elite European and global heritage brands such as ATB, Brook Crompton, Morley, Laurence Scott, Schorch, and OLI.
By combining GE's historical design paradigms with Wolong's intelligent global supply chain ecosystem, Shaanxi Nanfang Motor Technology Co., Ltd delivers unparalleled motor efficiency, custom engineered configurations, and localized support for major cross-border heavy engineering projects.
Unifying American Industrial Design with German Precision and Japanese IoT Innovation.
The integration of General Electric's industrial motor engineering into the Wolong manufacturing blueprint has created a formidable technology roadmap. Our future engineering strategy focuses on three fundamental pillars: Ultra-High Energy Efficiency, Digital Diagnostics & Integration, and Subsea/Hazardous Zone Resilience.
By leveraging research and development hubs in Europe (Austria & Germany), Japan, and Shanghai, we are accelerating the transition from standard induction AC motors to High-Efficiency Permanent Magnet Synchronous Motors (PMSM) conforming to IE4 and IE5 performance targets. This design pipeline incorporates multi-physics digital simulations to resolve thermal management constraints, magnetic circuit design, and structural resonance prior to physical foundry casting.
At our advanced manufacturing installations in China, Wolong has implemented a fully integrated Industry 4.0 workflow. We bypass the supply chain choke-points commonly encountered by traditional Western manufacturers. Our internal ecosystem ensures complete process control—from raw silicon steel lamination processing to automatic CNC frame machining and robotic stator winding.
This scale allows Shaanxi Nanfang Motor Technology to optimize procurement cycles, ensuring that large-scale project developers receive bespoke high-voltage induction or synchronous motors on shortened lead times. Through integrated logistics hubs in China, we manage land, sea, and rail shipping channels directly to Europe, Southeast Asia, Australia, and the Americas, assuring stability in global infrastructure delivery.
Integrating over 500 cumulative years of elite manufacturing history, pioneering technology, and application engineering.
Acquired in 2011, Austria’s ATB Group brought premier motor technology to our portfolio. ATB includes Morley, boasting a 130-year legacy in severe-duty underground mining motors, delivering reliability under heavy mechanical stresses.
Renowned for low starting current systems, Laurence Scott historically equipped nuclear power stations and marine defense vessels. They are the ideal choice for high-reliability municipal water pumping and grid protection layouts.
Pioneers in energy efficiency and flameproof solutions. Schorch (est. 1882) defines quality in European petrochemical drives. Brook Crompton offers highly versatile low and medium voltage drive packages.
CNE (Nanyang Explosion-proof Group) represents China's premier scientific explosion-proof hub. Merging with General Electric in 2018 has created a powerhouse for petrochemical, mining, and oil & gas drives.
A granular overview of the components that make GE and Wolong AC Motors the benchmark of industrial endurance.
The rotor features a rugged squirrel cage design. Cast aluminum rotors are produced using centrifugal or die-casting techniques, ensuring a single-piece construction that integrates the rotor bars and end rings. For high-capacity high-voltage AC motors, copper bar rotors are utilized, backed by advanced bar-securing and end-ring induction welding. High-speed configurations employ high-tensile retaining rings to prevent distortion during rotational surges.
Constructed from low-powder, high-mica content tape reinforced with glass cloth and polyester film. Following structural winding, the core goes through the Vacuum Pressure Impregnation (VPI) process. This ensures void-free resin absorption, maximizing dielectric strength, preventing moisture ingress, and protecting the stator against thermal degradation under high mechanical load cycles.
Designed using digital multi-physics simulation platforms, our frames utilize premium grade cast iron or high-tensile structural steel. Excellent thermal dissipation fins are cast directly into the shell to prevent heat pockets. The physical design features built-in vibration-damping support ribs, raising the motor's natural frequency and preventing resonance when paired with variable speed drives.
Comprising a lightweight fan cover body, internal air guide cylinder, high-strength protective window, and acoustical silencer plates. By positioning the air intakes on the lateral side, the design minimizes noise generation from airflow directional shifts. The fan assembly meets IP22 protection rating, ensuring total personnel safety while optimizing air delivery path efficiency.

Enables direct access to Australia’s mining sector. Wolong’s compliance with TestSafe guarantees our underground coal mining drive motors can operate in tough Australian subterranean sites.
Delivering high-integrity drive systems for heavy industrial sectors globally.
Operating inside explosive atmospheres requires certified explosion-proof drives. Our YE3 and YBX3 low-voltage, alongside high-voltage flameproof configurations, run pipeline pumps, offshore drilling machinery, and refinery gas compressors safely.
With dust and mechanical impact, our heavy-duty YBU/YBUS/YBK3 flameproof asynchronous motors power tunnel boring machines, continuous miners, and heavy-duty conveyor belts under demanding subterranean conditions.
Utilizing Laurence Scott technology, we supply custom motors with low starting current designs. These systems prevent supply voltage sag on auxiliary systems, ensuring secure operation for nuclear cooling loops and industrial power grids.
Expert technical answers regarding OEM GE AC Motor configurations, ordering logistics, and performance specifications.
In 2018, Wolong Electric Drive Group completed the acquisition of General Electric's (GE) industrial motor business division. Shaanxi Nanfang Motor Technology Co., Ltd is an authorized master distributor for Wolong Group. Through this channel, we supply global engineering buyers with OEM GE AC motors and Wolong brand systems, backed by full design heritage, technical support, and warranty coverage.
Yes. Our engineering departments specialize in manufacturing custom AC motors for direct drop-in replacement. We match shaft configurations, mounting dimensions, terminal box orientations, and torque profiles of older GE installations, minimizing plant downtime during upgrades.
VPI replaces traditional varnish immersion by drawing a vacuum, then forcing insulation resin under pressure deep inside the stator coils. This process eliminates microscopic air pockets, preventing localized electrical discharge (corona effect), boosting thermal dissipation, and securing the windings against vibration wear.
For areas containing combustible dusts (such as grain processing, pulverizers, and coal handling), we offer YFB3 and related series carrying ATEX/IECEx Zone 21 and Zone 22 dust-explosion-proof approvals, rated to prevent dust ingress and surface overheating.
Yes. Our YVF and BPY-S30 series are designed for variable speed control. These motors feature insulated bearings to block harmful shaft currents and use auxiliary cooling fans to maintain safe operational temperatures across wide speed ranges.
