Shaanxi Nanfang Motor Technology Co., Ltd. is the key authorized global partner and distributor of Wolong Electric Drive Group Co., Ltd., a powerhouse founded in 1984 and listed on the Shanghai Stock Exchange (SH600580) in 2002. Today, Wolong operates a massive footprint comprising 3 strategic global manufacturing bases, 39 hyper-automated factories, and 3 internationally recognized R&D centers.
Wolong's growth strategy centers on global brand integration, bringing legendary motor brands under a single standard of excellence. With major technological centers in Europe (Austrian ATB Group, Laurence Scott, Schorch, Brook Crompton), China (CNE Nanyang Explosion Protection), and strategic ventures in industrial drives (GE Industrial Motors), Wolong represents the pinnacle of three-phase AC induction engineering and custom system control.
By producing components within domestic economic clusters, our Chinese operations benefit from localized access to high-grade cold-rolled silicon steel, high-purity electrolytic copper, and heavy structural castings. This logistics integration results in shorter lead times and superior manufacturing cost efficiencies compared to Western alternatives.
Our collaborative global platform enables dual testing schemes matching both IEC and NEMA requirements. Our test beds handle full-load, temperature-rise, vibration, and acoustic spectrum tests on drive systems up to 15,000kW. High-voltage insulation reliability is verified through advanced partial discharge measurements.
Integrating centuries of European engineering pedigree (Austrian ATB, Laurence Scott, Schorch, Brook Crompton) with the raw industrial capacity of Shaanxi Nanfang Motor and Nanyang Explosion Protection (CNE). We design, manufacture, and export tailored, cross-compliant electrical drives.
To achieve global market leadership, WOLONG strategically acquired premier engineering organizations worldwide. This technology transfer enables us to deliver local technical support, high-standard explosion-proof certifications, and precision component sourcing across all continents.
In 2011, WOLONG acquired 97.94% of the Austrian ATB Group, positioning the group as a premier global motor manufacturer. Under ATB, brands like Morley and Laurence Scott brought unparalleled industry expertise:
Morley Motors has a 130-year lineage dedicated to heavy-duty underground coal mine operations. The brand represents rugged casing design and high-safety standards in hazardous mining environments.
Laurence Scott pioneered low-starting-current solutions and high-voltage generator designs for British nuclear facilities and naval fleets. This expertise enables us to support demanding grid requirements.
Brook Crompton Motors integrated into the Wolong ecosystem, bringing over a century of motor design experience. Brook Crompton is recognized for high-efficiency design, developing the "W" and "10" series low, medium, and high-voltage AC motors configured for harsh and variable-speed operations.
Schorch Electric Motors, established in Germany in 1882, has provided standard and custom drive systems for demanding industrial projects. Schorch designs reliable drives for chemical plants, offshore oil platforms, test setups, and municipal water systems.
In 1999, WOLONG partnered with OLI Vibration Motors in China to manufacture specialized industrial vibrators and monitoring systems.
In 2018, General Electric (GE) Industrial Motors division joined Wolong. GE's decades of experience in heavy-duty commercial and industrial electric equipment enhanced our engineering capacity in oil and gas extraction, refinery operations, pulp and paper processing, and metallurgy.
To support seamless international integration, our manufacturing processes are certified to meet major international standards. This comprehensive compliance helps mitigate trade barriers and simplifies procurement.

TestSafe
All production facilities operate under strict ISO management. Our quality assurance systems cover raw material receipt, intermediate stator inspection, rotor dynamic balancing, and final run-testing, providing high product reliability.
Our flameproof (Ex d), increased safety (Ex e), and pressurized (Ex p) motors are certified to international IECEx and European ATEX standards. This supports safe operation in volatile refinery, petrochemical, and mining zones.
For applications in the US, Canada, and Mexico, we provide electric drives designed to NEMA MG-1 standards. These units feature certified performance characteristics and carry UL and CSA approvals.
TestSafe certification enables the export of our explosion-proof mining drives to the Australian market. This compliance confirms our coal mine machinery meets the safety requirements for Southern Hemisphere mining projects.
In midstream transportation and downstream refining, high-efficiency positive-pressure shell motors (YZYKK series) and variable-frequency water-cooled explosion-proof motors (YBBP series) power centrifugal compressors, pipeline transport pumps, and cooling fans in volatile gas environments.
Heavy-duty flameproof water pump motors (YBRB series) and conveyor drives (YBSD series) operate reliably in wet, dusty, and methane-heavy environments. Designed to withstand mechanical shock loads, they support continuous mining extraction operations.
Our high-voltage synchronous drives and high-efficiency low-voltage induction systems (WE3, YE3) power circulating water pumps, municipal intake plants, district cooling towers, and auxiliary fans, helping operators control energy consumption.
Global energy regulations require higher efficiency classes to control operating costs. Our WEPM permanent magnet synchronous motors (PMSM) are engineered to meet IE4 and IE5 standards, helping reduce energy consumption and operational emissions.
Modern plants rely on predictive maintenance. By integrating digital vibration sensors (such as OLI Ex-sensors) and temperature probes, our smart motor systems enable real-time telemetry. This helps operators identify bearing wear and insulation degradation early to prevent unplanned downtime.
Our VFD-compatible motors are designed to withstand high voltage rise rates (dv/dt) without premature insulation failure. Utilizing advanced insulation systems, they provide reliable performance when paired with modern variable frequency drives.
Our manufacturing practices prioritize sustainability, using lead-free varnishes, low-emission processing materials, and highly recyclable copper and iron components to support circular economy goals.
IEC standards (primarily IEC 60034) define motor frame dimensions in millimeters, specify metrics in metric terms (kW), and categorize efficiency class ratings as IE1 through IE5. NEMA standards (NEMA MG-1) use imperial measurements (inches, horsepower) and define standard configurations for North American installations. Shaanxi Nanfang Motor provides both IEC and NEMA designs to ensure global compatibility.
Vacuum Pressure Impregnation (VPI) extracts air pockets from the stator winding insulation under vacuum before injecting solventless resin under pressure. The resin cures into a solid, void-free matrix that provides high mechanical strength, moisture protection, and dielectric reliability under thermal stress.
Permanent Magnet Synchronous Motors (PMSMs), like our WEPM series, utilize high-coercivity magnets within the rotor, eliminating rotor copper losses. This design offers high efficiency at partial loads and compact frame dimensions, which makes them suitable for variable-speed applications.
TestSafe certifies that electrical equipment meets high explosion-proof safety criteria. For underground coal mines, which are subject to methane gas and fine coal dust, TestSafe certification is required to import and operate Chinese-manufactured mining motors in Australia and associated markets.
We provide a range of cooling options depending on the application: IC411 (totally enclosed fan-cooled), IC611 (with air-to-air heat exchangers for high-voltage motors), and IC81W (water-cooled systems). Water cooling is suitable for spaces where quiet operation or high power density is required.
Shaanxi Nanfang Motor coordinates ocean and intermodal freight from major Chinese ports. Motors are secured in export-grade, moisture-sealed, anti-vibration crating to ensure they arrive in ready-to-install condition at your facility.
