Select industrial three-phase low and high voltage AC motors from the global manufacturing base, completely certified for ATEX, IECEx, and CE requirements.
In modern industrial operations, motor efficiency is critical to achieving carbon neutrality and sustainable energy objectives. As industrial systems expand in complexity, the integration of premium efficiency classes, specifically IE3, IE4, and IE5 standards under the International Electrotechnical Commission (IEC), is no longer optional—it is a regulatory mandate across major global markets.
At the center of this transition are IEC-standard motors. Equipped with CE certification, these systems ensure seamless deployment across EU regions while adhering strictly to global energy directives. Navigating this marketplace requires strategic alignment with suppliers who offer not just products, but verified certification portfolios, comprehensive global support infrastructures, and technical expertise designed for hazardous, explosive, and high-demand heavy industrial environments.
Understanding the structural requirements of IEC and CE-certified motors ensures long-term operational success:
Establishing global leadership in motor design and control systems through technology acquisitions and specialized industrial manufacturing excellence.
Shaanxi Nanfang Motor Technology Co., Ltd. is the authorized distributor of Wolong Electric Drive Group Co., Ltd. founded in 1984 and listed publicly in 2002 (code SH600580). Over decades of scientific development, Wolong has grown to establish 3 central manufacturing bases, 39 advanced manufacturing factories, and 3 global R&D centers. Focused deeply on motors and integrated drive control systems, Wolong executes a multi-brand strategy that positions the group at the forefront of global industrial engineering, delivering reliable, high-efficiency solutions to demanding engineering markets.
In 2011, WOLONG Group acquired 97.94% of the Austrian ATB Group, a major player in European motor production. This acquisition brought renowned legacy brands under Wolong's technological umbrella, including:
Adding to its portfolio, Brook Crompton Motors brought over a century of experience in motor design and innovation, leading the development of highly efficient systems like the "W" and "10" series for harsh industrial areas.
Schorch Electric Motor, established in Germany in 1882, has set standards for drive systems in oil, gas, power generation, and water treatment. OLI Brand, a global leader in high-performance vibration motors and sensors, has partnered with Wolong in China since 1999 to serve specialized materials handling markets.
In 2015, Nanyang Explosion Protection Group (CNE), China's largest scientific R&D base for explosion-proof motors, integrated into the Wolong Group, broadening its capability in oil, chemical, and nuclear power applications.
In 2018, General Electric (GE) Industrial Motors joined Wolong. As a legacy manufacturer of commercial and industrial equipment, GE provides extensive technological support for Wolong's oil and gas, petrochemical, and mining product lines, reinforcing the group's global competitive edge.
Providing optimized drive solutions for hazardous environments and energy-saving setups worldwide.
Our motors are certified to conform with stringent explosion-proof safety requirements, ensuring secure operation in volatile, gas-heavy, and coal dust environments globally.
Available in IE3, IE4, and IE5 specifications. We offer permanent magnet synchronous motor technologies that reduce energy consumption and operational wear.
From low-voltage variable frequency drives to high-voltage positive pressure designs (YZYKS), we cover critical industrial requirements.
Precision-engineered components built to withstand extreme stress and optimize electrical-to-mechanical energy transfer.
Features squirrel cage designs utilizing cast aluminum rotors produced via centrifugal casting or high-pressure die-casting. This construction integrates the rotor bars and end rings into a single piece to ensure structural integrity and optimize torque characteristics. For high-capacity applications, copper bar rotors with robust end-ring welding and safety retention rings are employed to ensure reliable performance under high rotation speeds.
Coils are crafted with polyester film reinforced with glass cloth and high-mica-content tapes. Post-assembly, the stator undergoes the VPI (Vacuum Pressure Impregnation) process to eliminate voids and moisture. This insulation system provides high mechanical strength, moisture resistance, and thermal stability under continuous operation.
Developed using structural and fluid multi-physics simulation platforms, our frames are made of high-strength cast iron or structural steel. They feature high heat dissipation capacity, rigid structural redundancy, and natural frequency isolation margins to minimize vibrations and withstand physical shocks.
Includes a compact fan cover, air guide cylinders, protective windows, and silencer plates. The side-entry air intake design avoids flow obstructions behind the motor, reducing energy losses and acoustic emissions. Rated to IP22, the system incorporates sound-absorbing materials to ensure quiet operations while protecting personnel from rotating components.
Securing absolute entry into global markets through verification against ISO, NEMA, CE, and safety agency standards.

WOLONG implements a comprehensive compliance strategy across the manufacturing chain to meet international trade requirements:
Customizing motor drive configurations to meet specific requirements in oil and gas, petrochemicals, mining, power generation, and automation.
In refining plants, explosive environments require ATEX/IECEx certified explosion-proof motors (such as the YBX4 and WEBP3 series). These systems power compressors, heavy pumps, and exhaust fans, preventing accidental ignition while maintaining continuous operation.
Mining operations face combustible coal dust and methane gas hazards. Specialized flameproof motors (like the YBK3 series and Morley designs) are built with heavy cast iron enclosures to contain internal explosions and support conveyors and ventilation machinery.
Operating in salt-spray and humid marine environments requires high corrosion protection. Wolong's 40kW electric outboard motors provide reliable propulsion and high torque efficiency for marine engineering vessels.
The industrial motor sector is evolving beyond basic mechanical engineering toward intelligent, connected drive systems. Wolong's technology roadmap focuses on three main pillars:
Expert insights on certification pathways, electrical configurations, and environmental safety measures for industrial motor applications.
High-capacity variable speed drive motors built to meet ATEX, IECEx, and CE specifications for demanding heavy industrial operations.
