Explore our top-tier catalog of certified three-phase asynchronous, explosion-proof, and variable frequency motors tailored for global industrial systems.
Low-voltage (LV) motors represent the foundational drive systems behind global industrial automation, mining operations, oil and gas logistics, and water treatment utilities. As manufacturing paradigms transition globally to adhere to stricter carbon neutrality targets, efficiency standards (IE3, IE4, and the emerging IE5) have shifted from optional benefits to strict legal mandates in major economies like the European Union (EU Ecodesign Regulations) and North America (NEMA standards).
Within this dynamic market, China has consolidated its status not merely as a high-volume manufacturing center, but as a technological pioneer in electric machine topologies. Shaanxi Nanfang Motor Technology Co., Ltd., as an authorized partner of the global leader Wolong Electric Drive Group, bridges the gap between sophisticated Chinese manufacturing and high-end global standards. We provide key technological solutions that satisfy demands for safety in hazardous environments, dynamic variable-frequency operation, and low total cost of ownership (TCO).

Authorized distributor of Wolong. Founded in 1984, Wolong Electric Drive Group successfully listed on the Shanghai Stock Exchange in 2002 (code SH600580). Over three decades of technology refinement has established Wolong as a pioneer in advanced motor design.
Today, Wolong operates 3 manufacturing bases, 39 factories, and 3 state-of-the-art Research & Development centers globally. Driven by a global brand integration strategy, Wolong blends domestic technical strength with century-old engineering brands, establishing a robust system that delivers reliable electrical drive solutions to heavy industries worldwide.
Engineered to support modern industrial processes, ensuring reliable performance in harsh, hazardous, or marine conditions.
Engineered to operate safely in volatile atmospheres. We supply multiple certifications to meet regional explosion-proof compliance laws across EU, Eurasian, and North American markets.
Featuring super-high efficiency ratings and Permanent Magnet (PM) synchronous motor options to help reduce operating costs and support green building or utility requirements.
From flameproof conveyor systems to low-noise variable frequency motors. Our systems support ventilation fans, mineral pumps, high-volume compressors, and municipal grids.
Wolong has established advanced R&D centers in China, Europe, and Japan, complemented by a central Research Institute in Shanghai. This structural design enables the group to incorporate global technologies into low-voltage and high-voltage motor topologies.
Our competitive advantage lies in the systematic acquisition of century-old industrial motor manufacturers, integrating their patents and structures directly into our design process:
Our path to global industry leadership through strategic integration and shared technological innovations.
Founded in Germany, Schorch began manufacturing reliable electric drives for water supply, shipping, and heavy industrial facilities.
Wolong was founded in Shangyu, China, focusing on developing domestic electrical drive technologies and scaling its production capacity.
Jointly commenced vibration motor manufacturing, scaling high-frequency MVE and sensor technologies for international markets.
Acquired 97.94% of the ATB Group, integrating Morley's mining expertise and Laurence Scott's low starting current capabilities.
China's largest research and production base for explosion-proof motors joined the group, establishing strong capabilities in hazardous environment engineering.
Strategic integration of GE's industrial motor business, bringing US standard industrial drive technologies into Wolong's global product portfolio.
A detailed look at the engineering components and advanced materials that drive our low-voltage electric motors.
Our stator coils use polyester film and glass cloth backing combined with high-grade, mica-dense insulation tapes. After winding, the stator core undergoes a computerized Vacuum Pressure Impregnation (VPI) cycle. This process removes air and moisture, resulting in a solid insulation structure with high electrical strength, thermal resilience, and moisture resistance, protecting the motor against harsh environmental conditions.
For standard high-torque duties, our squirrel-cage rotors are cast from high-purity aluminum using centrifugal or high-pressure die-casting processes, creating a uniform, single-piece structure. For heavy-duty industrial tasks, we employ copper bar rotors with TIG-welded end rings and dynamic balancing to support high starting loads and reduce thermal fatigue during frequent start-stop operations.
Designed using dynamic structural and fluid multi-physics simulation platforms, our heavy-duty cast iron frames feature high structural redundancy. This simulation isolates vibration frequencies and optimizes airflow patterns over the cooling fins, lowering temperature rise and improving mechanical durability.
Our low-noise cooling systems feature acoustic-lined fan covers, protective window configurations, and inline silencer plates. Side air intake paths reduce turbulence and propagation noise. Designed to IP22/IP44 standards, they protect workers while maintaining high ventilation rates.
Our products comply with major global industry standards, helping to streamline import, installation, and operation processes.
