Engineered for extreme reliability under hazardous conditions. Explore our high-efficiency electric motors complying with rigorous global IECEx, ATEX, and NEMA standards.
Electric motor-driven systems account for approximately 46% of all global electricity consumption, spanning municipal pumps, mining drives, and heavy oil refiners. As governments mandate compliance with carbon neutrality metrics (such as the European Green Deal and NEMA Energy Efficiency Policies), industrial energy audits are undergoing structural changes. High-efficiency motors (ranging from premium IE3 to hyper-efficient IE4 and ultra-premium IE5 permanent magnet standards) are no longer optional—they are the bedrock of operational sustainability.
By upgrading from standard induction configurations to optimized multi-physics electric motors, procurement directors mitigate massive operational costs. Over a typical 20-year motor lifecycle, the purchasing cost constitutes less than 2% of the Total Cost of Ownership (TCO), while energy consumption accounts for over 97%. Choosing high-efficiency machinery dramatically improves the operational bottom line, guaranteeing rapid payback ratios.

Integrating Europe's historic engineering brands with China's modern supply chain capabilities.
Acquired in 2011, Austria-based ATB is one of the three major European motor manufacturers. Highly renowned in the European market, ATB brings high-specification mining and petrochemical drive systems to the group, including the legendary Morley mining motor line.
Brook Crompton stands as a venerable and highly skilled participant in the electric motor sector, boasting over a century of expertise in electric motor technology and design. Its premium "W" and "10" series lead the industry in low-voltage and medium-voltage energy efficiency.
Schorch (founded 1882) sets the global standard for high-power customized drive systems, serving oil, gas, and water supply projects. Laurence Scott specializes in equipment with low starting currents, providing generators and auxiliary systems for nuclear power plants and naval vessels.
In addition to ATB, Brook Crompton, and Schorch, Wolong acquired Nanyang Explosion Protection Group (CNE) in 2015, which is China's largest research and production base for explosion-proof motors. CNE’s specialty motors are widely used in coal mines, oil pipelines, and nuclear power projects.
In 2018, General Electric (GE) Industrial Motors partnership officially joined the Wolong ranks. As a global pioneer in industrial and commercial electrical equipment, GE's integration with Wolong enhanced the design of custom machines used in oil extraction, marine propulsion, and heavy refining.
Analyzing the components that enable outstanding thermal management, mechanical strength, and electrical performance.
Featuring squirrel cage designs produced via centrifugal aluminum casting or die-casting techniques. Pure aluminum is poured into the slots of the rotor core, forming a single-piece construction that integrates rotor bars and end rings. For large-capacity motors, copper bar rotors with advanced end-ring welding ensure exceptional structural integrity and starting torque properties.
Our stator coils are crafted using polyester film reinforced with glass cloth, employing high-mica content tape. Following the Vacuum Pressure Impregnation (VPI) process, winding and insulation are transformed into a single structure that exhibits outstanding dielectric properties, moisture resistance, and thermal stability (Class F/H classification).
Designed using multi-physics simulation platforms (fluid-thermal and structural analysis), our high-strength cast iron (or structural steel) frames feature large safety margins. This structural stiffness minimizes vibration, provides high shock resistance, and ensures efficient heat dissipation, leading to lower operating temperatures and longer bearing life.
Comprising an optimized fan cover body, air guide cylinder, silencer plates, and sound-absorbing lining materials. Side air inlet channels optimize the airflow path and prevent recirculation. Rated IP22 for finger-safety, this system reduces turbulent energy loss, lowering overall noise levels while maintaining high cooling performance.
Operating out of highly integrated manufacturing hubs in China (such as Nanyang and Shangyu), Shaanxi Nanfang Motor Technology Co., Ltd utilizes advanced supply chain logistics to deliver motors worldwide. China's industrial ecosystem provides a complete supply chain for electric motors—ranging from electrical steel and high-purity copper windings to rare-earth permanent magnets (NdFeB) and precision castings. This integration ensures competitive production timelines and cost efficiencies.
By leveraging automated stator winding, advanced VPI technology, and digital testing benches, our manufacturing facilities achieve stable quality control. With warehouses located near key logistics hubs, we guarantee safe shipping and prompt delivery to markets across the Americas, Europe, Asia, and Australia, maintaining uninterrupted project timelines.
Our motors comply with major international certifications, facilitating smooth integration into global markets.
ISO 9001: Establish a solid manufacturing quality management foundation across all production sites, ensuring reliable products and services.
NEMA Standards: Testing protocols verify torque, current limits, insulation, and efficiency parameters, securing UL (Underwriters Laboratories) and CSA (Canadian Standards Association) compliance for the North American market.
IECEx & ATEX Standards: Ensuring design compliance for low and high voltage explosion-proof motors, supporting safe operation in hazardous environments within the European Union and globally.

Featuring DNV type-approval certificates, our low-voltage marine motors power thrusters, water circulation pumps, and onboard auxiliary systems.
Expert answers to common questions about buying and operating high-efficiency motors.
According to IEC 60034-30-1, shifting from Premium Efficiency (IE3) to Super Premium (IE4) or Ultra-Premium (IE5) reduces motor losses by an additional 15% to 20%. In high-duty industrial processes operating over 8,000 hours annually, this shift can lead to energy cost savings that cover the motor's initial acquisition cost in less than 18 months.
Our explosion-proof motors (such as the WEX3, YBBPX, and YBFBX3 series) are certified by leading global notification bodies under ATEX and IECEx directives. We utilize heavy-duty cast-iron enclosures designed to contain internal explosions without propagating flames to the surrounding atmosphere, together with Class F/H insulation and VPI treatments to limit surface temperatures.
While die-cast aluminum rotors are highly cost-effective and reliable for standard frame sizes, copper bar rotors are preferred for large high-voltage motors. Copper's higher electrical conductivity reduces rotor losses, leading to higher overall motor efficiency, lower heat generation, and better structural stability under high start-up currents.
As an authorized distributor of Wolong, we have direct access to its engineering facilities. We provide customized motor designs, including modifications to shaft dimensions, specialized mounting frames, custom voltage and frequency configurations, tailored VFD controls, and sensors for vibration and temperature monitoring.
