Engineered for extreme performance and strict compliance across global hazardous, mining, and industrial environments.
Shaanxi Nanfang Motor Technology Co., Ltd. is the authorized global distributor of Wolong Electric Drive Group Co., Ltd. (founded in 1984 and listed on the Shanghai Stock Exchange, code SH600580). Over nearly four decades of strategic growth, Wolong has consolidated its presence globally, operating 3 key manufacturing bases, 39 intelligent factories, and 3 global R&D centers.
This unified network is dedicated to engineering state-of-the-art electric motors and power control architectures. By bringing together legendary industry brands, Wolong delivers unparalleled design reliability, material optimization, and energy efficiency solutions worldwide.
Learn More About Our CapabilitiesComprehensive explosion-proof compliance protecting processes in hazardous areas, dust-ignition environments, and harsh deep mines.
Significant power savings utilizing advanced induction designs and modern permanent magnet synchronous motors (PMSM).
Spanning marine low-voltage auxiliary motors, high-voltage positive pressure machines, and heavy coal cutting shearer motors.
Purchasing high-efficiency motors from premium Chinese factories like Wolong provides global OEMs and operators with unique structural advantages:
Chinese production benefits from localized supply of critical raw materials, including high-grade electrical steel (silicon steel laminations) and advanced rare-earth neodymium magnets. This eliminates supply chain disruption risks and lowers raw material markup costs.
Wolong has integrated motor and drive control research centers in China, Europe, and Japan. The Shanghai Central Research Institute works to match international standards while driving innovation in thermal design, fluid dynamics, and insulation reliability.
Leveraging high-speed automated winding machines, robotic laser cutting, and computerized stator press lines, our factories guarantee minimal human error, exceptional insulation integrity, and high mechanical consistency across high-volume shipments.
In 2011, Wolong acquired 97.94% of the Austrian ATB Group, a leading European motor manufacturer. This brought the storied brands of Morley and Laurence Scott under the Wolong umbrella.
Morley boasts a 130-year history specializing in underground coal mining equipment, serving as a global standard for explosion-proof safety and robust heavy duty build. Laurence Scott, a pioneer in supplying specialized motors for nuclear power generation and low starting-current systems, also builds naval auxiliary generators. Following its integration into Wolong, Laurence Scott has won the prestigious Queen's Award for three consecutive years.
With more than a century of motor design heritage, Brook Crompton Motors joined the Wolong Group, bringing its recognized "W" and "10" series low, medium, and high voltage AC motors. They are engineered to operate reliably in highly corrosive, chemically active, and hazardous environments.
Similarly, Germany's Schorch, established in 1882, has set the benchmark for heavy industrial drive systems. Schorch designs serve key projects in petrochemical refining, municipal water supply, metal extraction, and pipeline transport.
Wolong's partnership with OLI since 1999 has secured a leading global position in electric external vibrators (MVE series) and flow-aid systems.
In 2015, China's largest specialized Ex-proof motor research and manufacturing base, Nanyang Explosion-Proof Group (CNE), joined Wolong. This strategic integration added key technologies for high-voltage flameproof (Ex d), non-sparking (Ex nA), and positive-pressure (Ex p) motors to the portfolio.
In 2018, the commercial and industrial division of General Electric (GE) merged with Wolong, sharing decades of material research and heavy industrial design, strengthening support for processing plants, power grids, and mining complexes.
Features a rugged squirrel-cage design utilizing high-conductivity cast aluminum produced via centrifugal casting, or pure copper bar designs with dynamic balancing. End rings are welded with structural precision, and high-speed configurations feature retaining rings to handle mechanical stresses under heavy loads.
Constructed using high-mica content tape, polyester films, and glass-cloth backing. Stators undergo full Vacuum Pressure Impregnation (VPI) to eliminate voids, protecting windings from environmental moisture, dust ingress, thermal cycles, and mechanical vibration.
Simulated using multi-physics platforms for thermal distribution and modal analysis. Made of high-grade cast iron or structural steel, our frames provide mechanical rigidity, excellent heat dissipation, and reduced noise levels during startup.
Features a compact design incorporating silencer plates, air guide cylinders, and side-located air inlets. This geometry minimizes flow turbulence, reduces noise levels, and achieves an IP22 rating to prevent direct contact with rotating elements.
Wolong maintains a global certification framework to simplify compliance for engineering, procurement, and construction (EPC) teams:
Our motors are integrated into key operations across heavy industries globally, driving critical equipment including fans, high-pressure pumps, compressors, and material handling systems:
Designed to handle continuous operations in hazardous atmospheres. Features like non-sparking (Ex nA) and positive-pressure (Ex p) casing prevent internal electrical arcs from contacting flammable gases.
Heavy coal shearer motors, water-cooled variable frequency drives, and rock cutting systems engineered to resist dynamic shocks, abrasive coal dust, and moisture.
Marine low-voltage auxiliary motors featuring DNV type approval. Anti-corrosive paints and condensation protection guard against salt-spray degradation.
Specialized generators and auxiliary drive motors designed for municipal wastewater systems, nuclear cooling towers, and boiler feed pumps.
