Discover our premium range of industrial AC synchronous and specialized explosion-proof induction motors, certified to major global benchmarks.
Shaanxi Nanfang Motor Technology Co., Ltd. is the strategic authorized distributor of Wolong Electric Drive Group Co., Ltd., bringing world-class motor designs and robust power transmission engineering to international industries. Established in 1984 and listed on the Shanghai Stock Exchange in 2002 (Code: SH600580), Wolong has evolved into an undisputed global giant. Today, Wolong operates 3 major manufacturing bases, 39 manufacturing plants, and 3 state-of-the-art R&D centers globally.
Through our comprehensive strategic layout, we combine China's high-efficiency supply chain ecosystem with the long-standing heritage of century-old industrial motor brands. This unique synergy enables us to solve complex driving challenges, optimize lifecycle costs (TCO), and provide highly dependable machinery for modern infrastructures.
The industrial landscape is undergoing a significant transition from asynchronous induction configurations to advanced AC Synchronous Motors and Permanent Magnet Synchronous Motors (PMSMs). Driven by international decarbonization mandates and strict environmental standards (like the EU's Ecodesign Directive), global procurement officers now prioritize motor efficiency (IE4 and IE5 classes), active power factor optimization, and operational reliability in severe process configurations.
AC Synchronous motors excel in applications requiring precise velocity control under fluctuating loads, offering constant speeds regardless of voltage drops. Their high power factor reduces line currents, minimizes reactive power demand, and lowers thermal losses across transmission systems. This makes them highly preferred for high-torque, low-speed heavy industrial configurations like extruders, mill drives, heavy compressors, and multi-megawatt fans.
Our motors meet and exceed IE4 and IE5 efficiency limits, drastically reducing energy usage. This helps facilities offset their initial capital expenditure within the first 12 to 18 months of continuous use.
Equipped with ATEX, IECEx, and EAC Ex classifications (Ex d, Ex e, Ex nA), our motors operate safely in explosive, volatile gas, and dust-heavy chemical zones.
The integration of global manufacturing legends under the Wolong brand translates directly to high reliability and advanced motor technology.
In 2011, WOLONG acquired 97.94% of the Austrian ATB Group, positioning itself as a world-renowned electric drive manufacturer. This brought together recognized names under one unified manufacturing platform:
This network of acquisitions creates a unified engineering platform. Designs created in our European R&D centers are built using China's advanced supply chain, ensuring cost-efficient production without compromising on quality.
Every component is engineered to deliver high electrical performance, thermal stability, and mechanical strength.
Our stator coils are insulated with high-grade polyester film reinforced with glass cloth and premium low-powder mica tape. The assembled stator undergoes a comprehensive Vacuum Pressure Impregnation (VPI) process, creating a robust, moisture-resistant, and thermally stable winding that easily handles electrical and mechanical stresses.
We offer cast aluminum rotors manufactured using centrifugal or high-pressure die casting for reliable performance and high starting torque. For larger, high-speed configurations, we use copper bar rotors with precision end-ring welding and retaining ring designs, ensuring reliable operation under high centrifugal force.
Designed using digital multi-physics simulation platforms, our frames are cast from high-tensile gray iron or fabricated structural steel. The design optimizes heat dissipation and resists mechanical shock, maintaining low vibration levels and a lower motor temperature rise.
The system features a streamlined fan cover, air guide cylinders, protective screens, and acoustic lining. Air is drawn from the side to avoid blockage-related turbulence, reducing noise levels while maintaining an IP22 rating to prevent accidental contact.
Manufacturing in China offers distinct advantages in vertical integration. Our supply chain secures raw electrical steel, copper windings, and high-performance permanent magnets directly from reliable sources, shielding buyers from price spikes. Advanced robotics and CNC machines ensure consistent quality and shorter manufacturing cycles compared to global alternatives.
To succeed in international trade, motors must comply with local grid characteristics, energy regulations, and environmental safety standards. Wolong holds a comprehensive portfolio of certifications to help clear trade barriers:
From deep underground mines to offshore platforms, our drive solutions power critical systems in all environments.
We supply explosion-proof motors (Ex d, Ex e, Ex nA) designed to power compressors, pumps, and cooling systems in hazardous zones, ensuring continuous operation under extreme ambient temperatures.
Through our Morley brand, we build specialized motors that resist heavy shock loads, dust, and water ingress, ideal for mine conveyors, shearers, and ventilation systems.
Our marine motors carry DNV, ABS, and Lloyd's Register type approvals. Featuring anti-corrosive coatings and specialized drainage, they power critical winches, bilge pumps, and thrusters.
Designed for tunnels, subway systems, and industrial complexes, our drive packages offer high starting torque and precise variable frequency speed control under high pressure.
