Driving global industries since 1984 with robust motor and control systems.
Shaanxi Nanfang Motor Technology Co., Ltd is the authorized distributor of Wolong. Wolong Electric Drive Group Co., Ltd was founded in 1984 and successfully listed in 2002 (code SH600580). Over more than 30 years of intensive growth, Wolong has expanded to encompass 3 major manufacturing bases, 39 state-of-the-art factories, and 3 high-tech R&D centers worldwide. We remain committed to a global brand strategy, leading in R&D, structural design, safety certifications, and commercial implementation across B2B channels.
Explore Distribution SolutionsWe bridge industrial challenges with compliant, high-efficiency mechanical solutions engineered to reduce TCO (Total Cost of Ownership).
We manufacture and export machinery compliant with stringent safety regulations. Our ex-proof systems guarantee flawless operation in highly hazardous zones.
Equipped with high-performance permanent magnet technology, reducing operational power drain by up to 25% while maintaining massive industrial torque output.
From low voltage NEMA motors to custom synchronous brushless high voltage drives and ATB Morley mining machines, our inventory answers any bulk B2B inquiry.
Consolidating European and North American engineering expertise under a single, unified supply chain framework.
In 2011, Wolong secured massive technological leverage by acquiring 97.94% of the Austrian ATB Group. This crucial expansion included legendary B2B brands such as Morley (boasting a 130-year lineage in underground coal mining equipment) and Laurence Scott (widely recognized for pioneering low-starting-current naval and power plant generators). This consolidation established Wolong as an undisputed heavyweight in structural mechanical engineering.
The inclusion of Brook Crompton and Germany's Schorch (established in 1882) brought centuries of design excellence to our product lines. Schorch drives serve heavy industries worldwide, including water management, tunnels, maritime shipping, and steel processing. Brook Crompton's high-efficiency "W" and "10" series low-voltage motors complement our portfolio with energy-efficient solutions for B2B buyers.
Regarding the industrial vibration sector, OLI holds the largest global market share for industrial vibrating motors (MVE series) and vibration sensors. Starting in 1999, Wolong launched dynamic joint operations with OLI in China. Additionally, in 2018, General Electric (GE) Industrial Motors joined our alliance, reinforcing our manufacturing capacity in petroleum, chemical processing, material sorting, and cement processing.
Leveraging fully digital production networks to guarantee zero-disruption B2B procurement globally.
At Shaanxi Nanfang Motor and Wolong, we have transitioned our domestic manufacturing bases into fully automated Smart Factories. By integrating dynamic ERP tracking, digital multi-physics simulation, and AI-driven quality assurance, we ensure shorter lead times and robust performance consistency across thousands of motor shipments.
This resilient B2B infrastructure prevents supply-chain bottlenecks, providing global distributors and engineering firms with a reliable partnership to insulate major projects against global logistics shocks.
Predictive Smart Diagnostics: Integration of vibration sensors with cloud-based IoT tracking to preempt failures.
IE5 Carbon Neutral Compliance: Global demand is shifting rapidly towards high-efficiency permanent magnet structures to minimize operational energy consumption.
Harsh Environment Specialization: Development of ultra-durable chemical and dust-proof coatings for severe operating conditions.
Our motors feature refined material configurations to withstand intense stress and maximize service life.
Our rotors utilize a high-strength squirrel cage structure, engineered with cast aluminum through advanced centrifugal or die-casting techniques. Molten pure aluminum is poured into the rotor slots, creating a unified structure integrating the bars and end rings. This ensures robust torque distribution and rotational balance. For heavy-duty motors, copper bar rotors are secured using precision welding, complemented by protective rings for high-speed reliability.
Our stator coils are insulated with high-grade polyester film reinforced with glass cloth, using low-powder mica tape with high mica content. The assembled stator undergoes Vacuum Pressure Impregnation (VPI) with premium solventless resin, creating a solid, moisture-resistant insulation system. This meticulous process ensures high dielectric strength, thermal stability, and mechanical endurance in challenging B2B environments.
Our motor frames are optimized using digital structural and fluid multi-physics simulation platforms. Cast from high-strength iron or structural steel, they feature robust walls and heat-dissipation fins. This design isolates inherent vibration frequencies and tolerates significant physical shocks, keeping stator temperatures well within safe limits under continuous operation.
Our low-noise fan cover system includes an integrated air guide cylinder, protective window, and silencer plate. The side-entry air inlet design mitigates blockages behind the motor and reduces noise from airflow turbulence. Incorporating sound-absorbing materials and achieving an IP22 rating, this lightweight assembly reduces high-frequency operational hums while preventing debris contact with the fan.

TESTSAFE Standard
ISO 9001 standard: Wolong maintains ISO 9001 compliance, helping B2B buyers navigate international trade requirements. Our motors are thoroughly tested to meet NEMA and IEC mechanical specifications. We verify electrical efficiency, insulation resistance, starting current, noise level, and structural integrity. For hazardous locations, our products carry IECEx and ATEX certificates, supporting export to European markets. Additionally, our TESTSAFE certification opens channels for coal mining drives to meet safety regulations in Australia and other international mining jurisdictions.
Supporting heavy-duty systems across global energy, industrial, and processing plants.
Widely deployed in mining, aggregate handling, and agricultural sectors. Our OLI-partnered industrial vibrating motors (MVE series) generate reliable material flow on vibratory feeders, screens, and hoppers, preventing material accumulation and maintaining processing efficiency.
In chemical facilities, our Nanyang explosion-proof motors (YBBP, YZYKS, YFBKK series) power high-pressure compressors, pumps, and fans. The increased safety designs mitigate ignition risks in hazardous environments containing explosive vapors or dust.
Our ATB Morley flameproof asynchronous motors are built for harsh underground coal mining operations. Engineered to resist impact, dust ingress, and moisture, they deliver high starting torque to drive heavy-duty belt conveyor systems.
Key information regarding technical specifications, custom manufacturing, and ordering processes.
We employ precision-machined shaft assemblies, reinforced cast iron frames, and dynamic balancing procedures. We conduct physical simulations to ensure structural redundancy and keep motor temperatures within target ranges under load.
