Explore our premium product line, catering to complex heavy industries, extreme marine setups, and hazardous industrial locations globally.
Industrial ventilation systems are the backbone of modern processing facilities, power plants, coal mines, and maritime vessels. The efficiency, reliability, and safety of these setups rely extensively on the motors that drive them. As leading global industries transition toward strict decarbonization protocols and strict safety directives (such as ATEX, IECEx, and NEMA guidelines), standard off-the-shelf motors often fail to satisfy custom mechanical footprints or complex electrical parameters.
This is where Shaanxi Nanfang Motor Technology Co., Ltd and the Wolong Electric Drive Group deliver critical support. By aligning high-efficiency technologies—ranging from standard asynchronous designs to next-generation permanent magnet platforms—we provide custom OEM configurations that match your system's aerodynamic performance demands while minimizing energy consumption and operational downtime.

With over a century of motor design heritage, Brook Crompton joined Wolong to drive advances in energy-efficient low, medium, and high-voltage motors, featuring their premium "W" and "10" series.
Dating back to 1882, Germany's Schorch is a global benchmark for drive systems in oil, gas, chemical processing, water treatment, shipbuilding, and infrastructure tunnel projects.
In 1999, Wolong established a strategic venture with OLI, the world leader in vibration motors and sensor systems, securing dominance in the bulk handling and material processing sectors.
Acquired in 2015, CNE (Nanyang Explosion-proof Group) is China's largest scientific research and manufacturing base for explosion-proof motors, supporting deep-sea, coal mine, and aerospace systems.
In 2018, Wolong acquired GE's commercial and industrial motor division, integrating GE's engineering expertise to expand its presence in heavy industrial materials and power generation.
Leveraging advanced manufacturing facilities across Austria, Germany, the UK, China, and the US.
Combining automated production, rigorous quality control, and localized raw material supply networks to deliver reliable heavy-duty industrial motors.
Our manufacturing centers employ automated machining centers, robotic winding systems, and computerized testing bays. This digital factory approach reduces human error, guarantees precise mechanical tolerances, and enables high volume output while maintaining strict safety standards.
Our production hubs are located in key industrial clusters in China, providing direct access to raw materials such as high-grade electrical steel, high-conductivity copper wires, and premium casting components. This proximity stabilizes production timelines and insulates against international shipping disruptions.
Heavy-duty motors require specialized transport solutions. We utilize high-strength, IP56-moisture-barrier packaging and shock-resistant timber casing to ensure every motor arrives in peak condition, ready for commissioning in marine, desert, or underground operations.
From initial electromagnetic design to final acoustic modeling, all processes are executed within a unified pipeline. This speeds up engineering revisions for custom OEM projects, reducing typical development cycles by up to 35% compared to conventional manufacturers.
Our motors are designed with high-grade materials and precise mechanical tolerances to ensure long-term reliability in demanding environments.
Our rotors feature a robust squirrel-cage design, with cast aluminum rotors produced using centrifugal casting or high-pressure die-casting to integrate the bars and end rings. For large-capacity motors, copper bar rotors are used with reliable brazing and end-ring welding. High-speed models include protective retaining rings to manage centrifugal stress.
Built with high-grade silicon steel laminations to reduce eddy current losses. The windings utilize polyester film and glass-fiber reinforced copper wire insulated with high-mica-content tapes. The complete assembly undergoes a Vacuum Pressure Impregnation (VPI) process to ensure moisture resistance and mechanical strength.
Designed using multi-physics structural and fluid simulation tools. Built from high-strength cast iron or structural steel, our frames provide excellent heat dissipation and high structural stiffness to minimize vibration levels and protect internal components.
Features an integrated air guide, protective mesh, and internal sound-absorbing baffles. The side-entry air intake design optimizes airflow around obstacles, reducing turbulence and acoustic emissions. The system offers IP22 contact protection for safety.
Our design and manufacturing systems are certified to meet international engineering and safety standards.

Developing high-efficiency, smart-connected electric motors to support modern industrial operations.
Our R&D efforts focus on advancing IE5 efficiency standards across our permanent magnet synchronous motor (PMSM) lines. By reducing copper losses and optimizing stator laminations, these motors lower overall operating costs and carbon emissions for ventilation operations.
We are incorporating vibration, temperature, and acoustic sensors directly into our motor frames. Connected to cloud-based predictive maintenance systems, this setup enables real-time tracking of motor health to help operators schedule maintenance and avoid unplanned downtime.
Our variable frequency drive (VFD) optimized motors (such as the WEBP3 series) are designed to provide wide speed ranges and high torque output across all operating speeds. This allows ventilation systems to adjust airflow dynamically based on system demand, reducing energy consumption.
We continue to research high-conductivity stator materials, low-loss magnetic alloys, and eco-friendly insulating resins. These material developments aim to increase power density and extend motor operational lifespans in high-temperature and chemically corrosive environments.
Our motors are engineered to meet the specific requirements of heavy industries worldwide.
Explosion-proof motors (such as the YBX3 and WEBP3 series) are designed to prevent accidental ignition in chemical plants, oil refineries, and gas transport facilities, meeting ATEX and IECEx Zone 1 and Zone 2 requirements.
Heavy-duty flameproof asynchronous motors (YBK3 and YBS conveyor lines) are built with durable cast-iron frames and dust-tight enclosures to handle the high vibration and abrasive conditions of underground mining.
Our YQ series low-voltage marine motors carry DNV, ABS, and Lloyd's Register type approval. These motors feature marine-grade anti-corrosive coatings and saltwater-resistant shaft sealing for shipboard duty.
Designed for power generation, metallurgy, and highway tunnels. High-voltage asynchronous motors (YKK and YZYKK positive-pressure shell models) drive large-diameter axial and centrifugal fans continuously.
Our distributed synchronous condenser system solutions help stabilize grid voltage and support active reactive power compensation in wind and solar power generation networks.
We design high-power-density electric motors (including our OEM 40kW outboard motors) to provide reliable, low-emission propulsion solutions for commercial and recreational vessels.
We work closely with engineering and procurement teams to deliver custom motor designs from specification to final commissioning.
