Highly certified industrial three-phase induction electric motors engineered to comply with global regulations and specific CE, ATEX, IECEx, and GOST/EAC standard profiles.
Optimizing heavy industries and process operations with smart, efficient, and compliant motor systems globally.
The global industrial sector faces a dual challenge: meeting stringent carbon-neutral targets while increasing operational throughput. High-voltage and low-voltage electric motors represent the consumption core of industrial electrical power. Modern industrial applications require high-efficiency solutions (ranging from IE3 up to IE5 classifications) that guarantee long life cycles and safe operations inside explosive and extreme atmospheres. Meeting international standards—such as CE certification for European markets and GOST/EAC regulations for Eurasian custom unions—is critical to mitigating compliance and operational risks.
Shaanxi Nanfang Motor Technology Co., Ltd. leads this transformation, delivering customized engineering options, dynamic speed drives, and hazardous environment explosion-proof capabilities. By combining Wolong's global production capacity and state-of-the-art designs, we build a seamless bridge between modern engineering theory and practical applications in oil refineries, mine operations, deep-sea exploration, and high-temperature fire safety ventilation systems.
Multiple certifications ensuring safety compliance across different global industrial zones and hazardous locations.
IE3, IE4, and IE5 energy-efficient platforms featuring permanent magnet designs that lower overall lifecycle costs.
Comprehensive product lines designed for variable frequencies, hazardous locations, and severe service operations.
Shaanxi Nanfang Motor Technology Co., Ltd. is the authorized global distributor of Wolong. Wolong Electric Drive Group Co., Ltd. was established in 1984 and listed on the Shanghai Stock Exchange in 2002 (code SH600580). Over the past three decades, Wolong has expanded to include 3 major manufacturing bases, 39 advanced factories, and 3 global R&D centers.
Focusing on electric motors and control solutions, Wolong pursues a global brand strategy, leading research, technology, modern manufacturing, and international sales. Through our engineering networks, we supply reliable drive systems to severe-duty applications worldwide.

TESTSAFE ScanAn inside look at our structural design, insulation systems, and dynamic components.
Constructed with polyester film and glass-reinforced tape containing high mica content. Following the Vacuum Pressure Impregnation (VPI) cycle, the stator core is sealed against moisture, dust, and vibration. This process enhances insulation, mechanical strength, and thermal stability in class F/H operations.
Featuring a cast aluminum squirrel-cage structure manufactured via centrifugal or high-pressure die casting. This integrates the rotor bars and end rings, delivering stable starting torque. For larger high-voltage models, dynamic copper bars with robust end-ring welding ensure mechanical integrity at high speeds.
Designed using multi-physics structural and fluid dynamic simulations. Cast in high-strength grey iron or fabricated steel, the frame provides robust heat dissipation and vibration isolation. It is engineered to absorb mechanical impact and limit temperature rise under continuous load.
Includes an integrated air guide cylinder, protective window, and acoustic silencer. The side air inlet bypasses adjacent obstacles, reducing ventilation losses and structural noise. The housing complies with IP22/IP55 safety standards to prevent direct contact with rotating elements.
Delivering certified power solutions to process and extraction industries worldwide.
Wolong operates 39 manufacturing plants and 4 global research facilities across China, Vietnam, the United Kingdom, Germany, Austria, Italy, Serbia, Mexico, and India. This footprint enables us to supply components that meet localized technical specifications and regulatory requirements.
