Engineered for extreme reliability under flammable environments, including Zone 1, Zone 2, and Underground Coal Mining hazards.
Deciphering the changing needs of international procurement executives, plant engineers, and EPC contractors.
Cross-border procurement demands motors that resolve local regulatory overheads. A single global platform offering combined ATEX, IECEx, UL, and CSA certifications drastically reduces project approvals and simplifies compliance across multiple geographic branches.
Operational costs represent over 90% of electric motor life-cycle expense. Modern factories look beyond initial purchase prices, optimizing for Ultra-Premium Efficiency classes (IE4 and IE5) as well as Permanent Magnet Synchronous Motor (PMSM) technologies to curb carbon footprint.
B2B applications call for mechanical design improvements: dynamic structural modeling, marine-grade anti-corrosive finishes, specialized thermal isolation classes (Class H), and high IP protection ratings (IP56/IP65/IP66) to endure aggressive chemical, mine, or offshore hazards.
Global scale production capability, advanced R&D hubs, and premium multi-brand industrial leadership.
Shaanxi Nanfang Motor Technology Co., Ltd. is the official authorized distributor of Wolong Electric Drive Group Co., Ltd. Founded in 1984, Wolong achieved successful public listing in 2002 (Stock Code: SH600580). With over three decades of dynamic industrial development, Wolong operates a vast infrastructure consisting of 3 major global manufacturing bases, 39 state-of-the-art factories, and 3 internationally recognized R&D centers.
Through dedicated pursuit of the global brand strategy, Wolong has gained a leading global market position across motor development, control engineering, manufacturing efficiency, and localized technical sales. We bring safety and motion control to heavy machinery, tunneling, marine propulsion, chemical processes, and mine exploration.
Discover how Wolong consolidated historic European and American brands to form a supreme global motor powerhouse.
Wolong acquired a 97.94% stake in the Austrian ATB Group, one of the three primary European electric motor manufacturers. This historic transaction integrated legendary sub-brands including Morley (underground coal mining motors with a 130-year legacy) and Laurence Scott (renowned for low-starting-current machines for nuclear plants and naval vessels).
With more than a century of electric drive mastery, Brook Crompton joined the Wolong Group, strengthening its capabilities in the development of low, medium, and high-voltage AC motors. This integration bolstered the development of premium high-efficiency motor lines, including the famous Brook Crompton "W" and "10" series designed for hostile applications.
Established in 1882 in Germany, Schorch joined Wolong in 2011. Known as a premier standard for high-performance and customized electric drive systems, Schorch delivers heavy-duty custom systems to critical sectors such as oil, gas, chemical processing, water management, shipbuilding, and deep tunnel infrastructure.
Since 1999, Wolong has partnered with OLI, a global leader in high-durability vibration motors and specialized explosion-proof vibration sensors. This strategic partnership delivers rugged electric vibrators to sorting, packaging, concrete consolidation, and heavy material handling industries worldwide.
In 2015, China’s primary R&D base for explosion-proof drives, Nanyang Explosion Protection Group (CNE), integrated into Wolong. This was followed in 2018 by the strategic acquisition of General Electric's (GE) commercial and industrial motor division. This combination consolidated Wolong's technological authority across major international heavy industries.
Custom OEM electric motors engineered to comply with precise operation, safety, and dynamic load configurations.
Wolong operates leading motor and drive control R&D facilities across China, Europe, and Japan, anchored by a centralized institute in Shanghai. Our technical teams develop advanced technologies that enable our products to perform at the highest levels of global motor engineering.
Our portfolio brings together trusted names in the electric drive industry. From Nanyang Explosion Protection to century-old brands like Brook Crompton, Morley, Laurence Scott, Schorch, and ATB, we offer comprehensive motor and control solutions across oil & gas, mining, and power generation markets.
Designed for reliable performance in hazardous locations, Wolong motors comply with stringent safety standards. Our explosion-proof products carry certified safety approvals from international organizations, including ATEX, IECEx, CU-TR (EAC), CSA, and SABS.
All low voltage flameproof and increased safety motors undergo extensive testing to confirm compliance with global safety standards. Our quality assurance protocol includes insulation resistance evaluation under high-temperature loads, partial discharge tests, water intrusion containment, vibration logging, noise tests, and flame propagation testing in our accredited laboratories.
Analyzing the design and materials that protect Wolong motors against volatile atmospheric hazards.
Our squirrel-cage rotors are built using centrifugal or high-pressure die-cast aluminum to ensure structural integrity and consistent torque. For larger frame sizes, copper bar rotors are utilized with welded end rings and retention components, minimizing start-up strain in high-inertia equipment.
Our stator windings use premium copper conductor wire wrapped in high-mica-content tape, insulated with polyester film and reinforced glass cloth. The completed assembly undergoes vacuum pressure impregnation (VPI) with solventless resin, creating a solid structure that resists moisture, chemical corrosion, and thermal degradation.
Developed using structural and thermodynamic simulation platforms, our high-tensile cast iron and steel frames feature optimized cooling fins. The rugged construction provides mechanical strength to absorb external shocks and contains internal explosion pressures without deformation.
The low-noise ventilation system integrates an aerodynamically designed air guide, protective mesh window, and acoustic lining. The side-entry air inlet minimizes flow disruptions, while the IP22-rated enclosure prevents foreign object entry and reduces overall operating noise.

Developing advanced technologies for high-performance explosion-proof industrial operations.
We are expanding our high-efficiency permanent magnet synchronous motor (PMSM) lineup. By eliminating rotor copper losses, these systems achieve IE5 efficiency levels, reducing energy consumption in variable torque applications like water pumps and cooling fans.
We integrate certified explosion-proof vibration and thermal sensors directly into our motor designs. Connected to machine-learning diagnostic software, these systems monitor winding temperatures, bearing wear, and structural vibrations to optimize maintenance schedules and prevent downtime.
As industrial hydrogen use grows, we are developing explosion-proof enclosures rated for Gas Group IIC atmospheres. These designs utilize specialized flame paths and sealing systems to prevent hydrogen ingress under extreme pressure conditions.
