Deep dive into international procurement policies, energy efficiency targets, and technical adaptations.
With international carbon taxation tightening, global heavy industry is phasing out low-efficiency motors. Utilizing advanced technologies like Permanent Magnet Synchronous Motors (PMSM) enables plants to reduce electricity consumption by up to 15%, lowering overall operational costs and footprint.
Underground coal mining, deep-sea exploration, and high-dust petrochemical processing require certified flameproof and increased-safety configurations. Double-chamber terminal structures and reinforced casings minimize electrical spark transmission risks in hazardous zones.
Integrating vibration sensors and real-time thermal diagnostics on critical machine frames allows engineering managers to detect winding and bearing decay days before a catastrophic failure, minimizing unplanned downtime.
Tailoring our electric motor solutions to key industrial application scenarios around the globe.
Our high-voltage variable frequency motors are designed to operate safely inside toxic gas processing units and offshore oil rigs. Using ATEX/IECEx/EAC-certified construction, they deliver steady shaft torque under massive pressure demands, powering large compressors and oil-transfer pumps.
Through our legendary Morley and CNE Nanyang brand assets, we build highly specialized tunnel boring machine (TBM) motors. These feature flameproof enclosures capable of containing internal gas explosions, avoiding ignite propagation inside coal tunnels.
Water management systems demand 24/7 reliability. Our YBRB series pump motors guarantee water tightness, protection against moisture corrosion, and structural heat-dissipation optimized for vertical pump mount setups.
As modern electrical grids integrate fluctuating renewable energies, our distributed synchronous condenser system solutions deliver essential reactive power compensation, stabilizing network voltages and grid frequencies.
Every element is simulated, optimized, and manufactured to withstand extreme mechanical stress.
The rotor features a highly durable squirrel cage design, utilizing advanced centrifugal aluminum casting or die-casting techniques. In this process, molten pure aluminum is poured directly into the slots of the rotor core, creating a single-piece construction that integrates the rotor bars and end rings seamlessly.
For larger-capacity, high-voltage motors, copper bar rotors are employed. These benefit from reliable mechanical bar securing and advanced end-ring welding procedures. The protective ring design on our high-speed motors guarantees mechanical stability under heavy dynamic load shifts.
The coil structure is crafted using polyester film reinforced with high-density glass cloth. By using low-powder mica tape or medium-powdered mica tape with rich mica content, the insulation offers optimal electrical breakdown threshold performance.
After extracting the billet, each winding undergoes the Vacuum Pressure Impregnation (VPI) process, curing into a robust, moisture-resistant insulation shield. This guarantees superior electrical performance, exceptional mechanical strength, and reliable thermal stability.
Our motor frames are optimized using a fully digital simulation platform that analyzes structural, fluid, and electromagnetic fields. Built from high-strength cast iron or structural steel, the frame boasts exceptional structural redundancy, excellent heat dissipation, and isolated natural frequencies. This mitigates resonances, enabling the motor to withstand mechanical shocks while minimizing overall vibration.
Comprising a reinforced cover body, an air guide cylinder, a protective window, and an integrated silencer plate, the low-noise fan cover system features a compact, lightweight design that minimizes structural vibration.
By placing the air inlet on the side, we optimize intake pathing around behind-motor obstacles. This prevents ventilation bottlenecks and reduces air turbulence noise. Sound-absorbing lining materials reduce acoustic emissions, while the IP22-rated outer cage protects operators from contact with rotating components.
Trace Wolong's international growth through acquisitions of historic global motor brands.
Wolong acquired 97.94% of the Austrian ATB Group, one of the three major European motor manufacturers. This acquisition integrated the Morley brand (representing nearly 130 years of underground coal mining expertise) and Laurence Scott (famed for low starting current nuclear pump drives and Royal Navy vessel auxiliary generators).
Schorch, established in Germany in 1882, joined Wolong. Schorch is recognized worldwide as a standard-setter for high-power, high-quality drive systems used in oil & gas, chemical plants, water distribution networks, and industrial test fields.
Brook Crompton Motors, a pioneer in energy-efficient drives (famous for their W and 10 series), joined the group. In 2015, China's largest explosion-proof research and production manufacturer, CNE Nanyang Explosion-proof Group, merged into Wolong, securing a leading position in Ex-proof drive solutions.
General Electric (GE) commercial and industrial motor division joined Wolong. As a historic manufacturer of industrial electrics, GE's integration bolstered Wolong's capacity to serve large-scale heavy industries (pulp & paper, cement, mining, marine) in North America and globally.
Our motor products undergo verification by global inspection bodies for application in hazardous areas.
Compliance certificates for gas and dust environments. Vital for operating electric motors in chemical processing plants and refineries across the European Union.
Verification of electrical safety insulation, starting torque performance, and enclosure parameters according to CSA and UL standards.
Guarantees conformance with European economic area safety regulations and high-efficiency limits, including electromagnetic compatibility criteria.
Validates design reliability under African mining environmental conditions, protecting operations from voltage drops and high particulate densities.
Testsafe is the largest coal mining equipment validation body in the Southern Hemisphere. Obtaining this mark opens access to Australian deep mining operations.
Ensures quality management systems are tuned to produce flameproof machinery, with total traceability of components from raw alloy to testing bench.
Where efficiency meets intelligence: the future of industrial motion control.
Our R&D efforts focus on shifting industrial motors from mechanical assets into smart nodes within the Industrial Internet of Things (IIoT). We integrate intelligent thermal interfaces, micro-machined vibration sensors, and insulation monitoring modules into the stator core.
To support global decarbonization, our engineers are developing IE5 ultra-premium efficiency Permanent Magnet Motors (PMSM). These systems feature rotor geometries optimized to minimize copper losses, reducing operating temperatures and energy consumption under variable load curves.
Furthermore, we are expanding local engineering centers in strategic regions, ensuring rapid customization of shaft profiles, terminal box entry routes, and installation footprints to accelerate modernization projects.
