Explore our first selection of energy-efficient, robust industrial motors certified for worldwide safety and high operating reliability.
Shaanxi Nanfang Motor Technology Co., Ltd. is the premier authorized distributor of 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 absolute titan in global motor development and motion control systems. With a strategic footprint that includes 3 primary global manufacturing bases, 39 state-of-the-art factories, and 3 localized R&D hubs, Wolong delivers highly customized and standardized low-voltage 3-phase asynchronous motors across every continent.
Wolong's global reach is built on a foundation of strategic integration. By acquiring some of the world's most recognized motor brands, Wolong has combined century-long European craftsmanship with Chinese manufacturing scale. Under the Wolong umbrella, brands like Brook Crompton, Morley, Laurence Scott, Schorch, OLI, and Nanyang Explosion-Proof (CNE), alongside assets from General Electric (GE) commercial and industrial motors, work together to provide a robust, unified engineering portfolio.
We supply comprehensive, internationally recognized certificates to facilitate compliance in challenging environments such as Class I Div 1/2 and Zone 1/2 applications.
Offered in IE3, IE4, and cutting-edge IE5 standards, as well as Permanent Magnet synchronous configurations, helping reduce total cost of ownership (TCO).
Backed by active technology development facilities across China, Europe, and Japan, ensuring that electromagnetic designs meet modern mechanical demands.
Explore the material selection and engineering processes that allow our low-voltage three-phase motors to operate in heavy-duty environments.
Our low-voltage motors feature a robust squirrel-cage design. The cast aluminum rotors are manufactured using advanced centrifugal casting or automated high-pressure die-casting. This process forces molten pure aluminum into the rotor core slots to form a single, solid piece containing the rotor bars and end rings.
For higher-capacity systems, we employ copper bar rotors with dynamically balanced, premium welded end-rings. A protective ring design is utilized on our high-speed motors to secure the copper bars against centrifugal forces, ensuring long-term mechanical stability.
The stator coils are insulated with polyester film and reinforced glass cloth, combined with high-grade, low-powder or medium-powder mica tapes. Every stator assembly undergoes the Vacuum Pressure Impregnation (VPI) process.
Under vacuum conditions, premium resin fully penetrates the stator structure, leaving no air gaps. This produces a well-insulated, mechanically rigid winding block with high resistance to moisture, chemical vapor, thermal cycling, and mechanical stress.
Developed using multi-physics simulation software, our cast iron or structural steel motor frames are designed with generous safety margins. This design minimizes resonance and optimizes thermal dissipation.
The deep-finned structure provides efficient convective cooling, lowering hot-spot temperatures within the windings. Additionally, robust mounting feet are designed to withstand high mechanical shocks and minimize vibrations across variable speed ranges.
Our low-noise cooling fan system consists of a lightweight, vibration-dampening fan cover, an air-guide cylinder, protective mesh windows, and integrated silencer plates.
The air intake is positioned to prevent blockage from nearby obstacles, maintaining a consistent airflow pattern and reducing aerodynamic noise. With an IP22 rating, the cover prevents accidental contact with the rotating fan blades while keeping operating sound levels low.
Through strategic acquisitions, Wolong has combined established motor brands into a single, global engineering network.
In 2011, Wolong acquired the Austrian ATB Group, gaining access to high-specification motor technology. ATB brands like Morley bring nearly 130 years of underground coal mining expertise, while Laurence Scott provides custom marine and power generation solutions. The addition of Schorch (established in 1882) further expanded our capability in severe-duty drives for oil, gas, and chemical processing.
The integration of Brook Crompton brought a legacy of energy-efficient motor design, including the premium "W" and "10" series for harsh industrial tasks. Furthermore, the 2018 acquisition of General Electric's (GE) commercial and industrial motor division added robust manufacturing standards, reinforcing our ability to support heavy industrial operations.
Nanyang Explosion-Proof (CNE) provides explosion-proof motor research and manufacturing capabilities for chemical, coal, and petrochemical applications. Partnering with OLI also allows us to supply specialized vibration motors and sensors for material handling and industrial processing.
Our low-voltage three-phase motors are certified to conform to international standards, ensuring compatibility across different regional grids.

Our integrated supply chain helps global OEMs manage risks, lower lead times, and access local technical service.
By manufacturing in China, we leverage a comprehensive industrial ecosystem. From high-grade electrical steel laminations and refined copper wiring to advanced casting foundries, our raw material sourcing is highly integrated. This allows Shaanxi Nanfang Motor to maintain cost stability, enforce strict quality controls at every stage, and shorten lead times compared to fragmented supply chains.
Through Wolong's international service network, we supply engineering support, spare parts, and diagnostic services in Europe, the Americas, the Middle East, and Asia-Pacific. Localized service centers help plant operators minimize downtime by providing rapid troubleshooting, custom winding adjustments, and bearing replacements.
Our low-voltage three-phase AC motors are configured to meet the specific demands of heavy industries worldwide.
Designed with explosion-proof enclosures (YBX3, YBX5, WEX3 series) to operate safely in volatile chemical processing zones containing combustible gases and vapors.
Equipped with reinforced frames, dynamic dust sealing, and high torque output, these motors power coal shearers, conveyors, and mining ventilation systems.
Features corrosion-resistant coatings, moisture-resistant VPI windings, and IP56/IP65 ratings to protect components against marine environments and salt spray.
