High-torque, high-efficiency explosion-proof motor portfolios developed specifically to withstand severe load cycles in hazardous zones.
Shaanxi Nanfang Motor Technology Co., Ltd. is the authorized primary distributor of Wolong Electric Drive Group Co., Ltd. Established in 1984 and listed on the Shanghai Stock Exchange in 2002 (Ticker: SH600580), Wolong has advanced to become a global heavyweight in electric motor manufacturing. Through three decades of deliberate technology integration and market expansion, the group has established a massive industrial network comprising 3 manufacturing bases, 39 advanced factories, and 3 localized R&D hubs worldwide.
Wolong's commitment to dynamic engineering translates into premium product supply chains spanning medium-to-high voltage industrial machinery, flameproof drives, and intelligent control architectures. Our collaborative distribution channels ensure comprehensive EPC contracting support, tailored application configurations, and post-installation reliability audits for global mining firms, petrochemical refiners, and municipal infrastructure networks.
Decarbonization, high-efficiency VSD integration, and explosion protection under extreme underground conditions.
Volatile energy costs and carbon reduction mandates are pushing mining procurement towards ultra-efficient IE4/IE5 permanent magnet systems, reducing operating costs by up to 15%.
Safety regulations demand robust certifications like ATEX, IECEx, and MSHA. Dual-flameproof and dust-ignition-proof ratings are vital for ventilation fans and continuous miners.
Variable Speed Drive integration provides soft-starting capabilities, reducing grid impacts and mechanical strain on large mine conveyors during heavy start-ups.
Information Gain Indicator: Modern underground mining operations operate under severe heat loads. Advanced motor design must prioritize thermal efficiency (Class H insulation run at Class B rises) to minimize heat output while avoiding catastrophic dust ignition risks.
Merging European design heritage with advanced Asian manufacturing scale.
In 2011, Wolong acquired a 97.94% stake in the Austrian ATB Group, positioned as one of Europe's top three motor manufacturers. This acquisition brought British heritage brands Morley and Laurence Scott under Wolong's technological banner. Morley, with a legacy spanning 130 years, is synonymous with heavy-duty coal shearer motors. Laurence Scott remains an industry pioneer, supplying low-starting-current heavy motors to nuclear plants and naval defense fleets.
Integrating Schorch (est. 1882) expanded Wolong's reach in massive petrochemical and marine drive technologies. The acquisition of Brook Crompton complemented Wolong's line with reliable industrial Low Voltage standard drives. Partnering with OLI vibration motors secured global leadership in concrete consolidation and dry bulk processing vibrators, establishing a complete mining-to-refining motor portfolio.
In 2015, Nanyang Explosion Protection Group (CNE), China's premier explosion-proof motor researcher and manufacturer, joined Wolong. In 2018, Wolong entered a strategic partnership with General Electric (GE), taking over its industrial motor operations. This integration blended GE's design standards with Wolong's cost-effective manufacturing capabilities, supporting critical industries like mineral processing, metallurgy, oil, and gas extraction.
How our integrated digital ecosystem ensures quality, control, and lead-time stability.
Our manufacturing facilities operate on an integrated Factory 4.0 infrastructure, coordinating material supply, automated component manufacturing, precision winding, and high-voltage insulation treatment in a single digital loop. This setup insulates our supply chains from global market disruptions, ensuring consistent lead times for bulk procurements and custom motor projects alike.
Using digital simulations, we test stator performance, fluid dynamics, and thermal patterns before physical assembly. This process guarantees that every explosion-proof motor meets international standards (such as Class H VPI insulation systems, dynamic balancing, and pressure-resistant enclosures) before dispatch.
Under the hood of industrial drives built for harsh, high-vibration applications.
Constructed using high-content mica tapes wrapped in polyester film and glass cloth. The entire stator assembly undergoes Vacuum Pressure Impregnation (VPI) with solventless resin, forming a solid dielectric block. This process eliminates internal air pockets, offering excellent moisture resistance, high dielectric strength, and reliable protection against mining dust and chemical vapors.
Features a heavy squirrel-cage design. Smaller frame sizes utilize centrifugal cast aluminum, forming integrated rotor bars and end rings for high-torque startups. High-power motors employ hand-brazed copper bar rotors with custom end rings, engineered to withstand thermal cycling and high startup currents during belt-conveyor startups.
Built from high-tensile cast iron or welded steel, our motor frames are designed using multi-physics structural and fluid simulation software. The rugged cooling fins maximize heat dissipation in environments with limited airflow, while thick casting walls protect internal components from falling rocks and severe physical impacts.
Features an optimized aerodynamic shroud and a high-strength bidirectional cooling fan. The system includes acoustic damping elements that minimize aerodynamic noise while maintaining high airflow rates. Rated IP22 to prevent accidental contact, it features side-entry air paths to prevent blockages in tight spaces.
Certified drives ready for integration into North American, European, and Australian heavy industries.
