Explore our top-tier explosion-proof, low-voltage, and high-voltage three-phase asynchronous motors designed for hazardous and rigorous industrial locations.
In modern industrial facilities, flanged electric motors (including IEC B5, B14, and NEMA standard face configurations) serve as the backbone of direct-coupled mechanical drive assemblies. For global procurement officers in oil and gas, heavy mining, municipal water treatment, and marine engineering, choosing a flanged motor involves navigating complex structural requirements and compliance matrix standards.
Proper flange alignment reduces shaft runout, prevents premature bearing failures, and minimizes structural vibrations. When procuring from China, engineering departments must evaluate mechanical construction parameters alongside electrical specs, ensuring that mounting tolerances, dynamic balancing classes, and structural rigidity match the intended operating conditions.
"Selecting the optimal flange motor configuration is no longer just a catalog choice; it requires rigorous alignment with ISO G1.0/G2.5 balance standards and dynamic heat distribution modeling under continuous loading conditions."
A partnership dedicated to delivering premier industrial drive solutions across global markets.
Shaanxi Nanfang Motor Technology Co., Ltd serves as the authorized global distributor of Wolong Electric Drive Group Co., Ltd. Founded in 1984 and listed on the Shanghai Stock Exchange in 2002 (code SH600580), Wolong has grown to become a world leader in motor and drive control technology. Wolong maintains 3 massive manufacturing bases, 39 advanced factories, and 3 state-of-the-art research and development centers worldwide.
By leveraging Wolong's international technology ecosystem and Shaanxi Nanfang Motor's dedicated technical consultation services, we ensure that global industrial projects receive highly reliable, certified products. Our engineering teams help configure solutions that optimize efficiency, limit operating costs, and meet localized environmental mandates.
Through a series of strategic acquisitions, Wolong has integrated several century-old engineering brands under its corporate umbrella:
Explore the underlying material science and advanced production processes that define our flanged and explosion-proof motors.
Featuring squirrel cage cast aluminum or premium copper bar configurations. Utilizing centrifugal cast methods and dynamic balancing up to ISO G1.0, our rotors reduce vibration, minimize stray load losses, and guarantee reliable mechanical connection to your shaft assembly.
Our stators feature premium polyester-imide film insulation and mica tape. The entire assembly undergoes a rigorous VPI process to eliminate air pockets, offering maximum moisture protection, high dielectric strength, and Class F/H thermal margins.
Engineered via 3D multi-physics fluid and thermal simulations, our high-tensile cast frames offer massive structural safety factors. The optimized cooling fin placement optimizes heat dissipation, significantly extending bearing and winding life.
Consisting of an air guide cylinder, high-durability fan, protective window, and structural silencer plate. This layout prevents vortex generation, lowers operational noise, and maintains an IP22/IP23 rating at the inlet to prevent foreign object contact. Specialized fan profiles match the directional cooling needs of different shaft speeds.
From regional origins to a unified global power in commercial & industrial drives.
Wolong acquired 97.94% of Austria's ATB Group. This integration brought Morley's 130 years of coal mining motor design and Laurence Scott's low starting current naval/nuclear systems into our product family.
Schorch (established 1882) joined Wolong, adding world-class drive systems for petroleum, natural gas pipeline compressors, water management, and shipbuilding.
CNE, China's largest scientific research and manufacturing base for explosion-proof motors, integrated with Wolong, creating one of the largest safety-certified production footprints in the world.
GE's commercial and industrial motor division joined Wolong. This expanded our product lineup to include heavy NEMA standard configurations for water treatment, pulp & paper, cement, and chemical processing.
Our electric motors carry international certifications, enabling hassle-free project approvals worldwide.
For operations in hazardous locations, compliance is non-negotiable. Wolong designs, builds, and tests flanged motors to satisfy national and international safety regulations:

Certified Global Distribution Networks
Engineered solutions for challenging settings, from offshore drilling platforms to deep underground mines.
For gas compressors, pipeline transit pumps, and refining equipment. Fully compliant with ATEX/IECEx Ex d (flameproof) and Ex p (pressurized) safety protocols.
High-torque drives for conveying belts, ventilation fans, and rock crushers. Built with robust mechanical construction to withstand dust, humidity, and mechanical shock.
Engineered for winches, cooling pumps, and propulsion units. Features certifications from DNV and BV, built with anti-corrosive properties for high-salinity marine environments.
Innovation focused on high efficiency, smart diagnostics, and carbon reduction.
As industries seek to achieve carbon neutrality, transition from standard induction motors to Permanent Magnet Synchronous Motors (PMSM) is accelerating. Wolong's TBVF series features outstanding power density and meets IE5 efficiency levels, even under partial load profiles.
By integrating direct-drive PMSM designs, projects can eliminate mechanical gearboxes, reduce footprint, simplify maintenance, and improve overall drive reliability.
Modern plants rely on real-time diagnostic data to avoid unplanned downtime. Our smart motor systems incorporate vibration and thermal sensors linked to cloud dashboards. Predictive algorithms analyze these signals to schedule maintenance before structural or winding failures occur, optimizing lifetime value.
