Direct supply of industry-standard, high-reliability extraction motors designed to withstand the harsh environments of Asturian and Andalusian mining basins.
Spain possesses a rich geological history, hosting one of Europe's most significant mineral resource pools. From the historical coal regions in the Asturian basin (Cuenca Minera de Asturias) to the expansive copper extraction operations in Andalusia's Pyrite Belt (such as Rio Tinto and Cobre Las Cruces), the demand for high-reliability, certified explosion-proof drive equipment remains paramount.
Furthermore, active potash mining projects in Catalonia (Iberpotash in Súria) require specialized machinery that operates under strict hazardous area regulations. Under EU directives, all electric motor systems installed in these subterranean operations must conform to the stringent ATEX Directive 2014/34/EU and receive approvals from certified European test facilities such as the Madariaga Official Laboratory (LOM) in Madrid.
Modernization within Spain's industrial sector is heavily focused on sustainability and efficiency. Mining operators are shifting away from older, energy-inefficient motor installations towards IE4 and IE5 super-high-efficiency induction and permanent magnet synchronous motors, dramatically reducing power consumption and grid load while maintaining continuous duty cycles under extreme conditions.
Shaanxi Nanfang Motor Technology Co., Ltd. is the authorized international distributor of Wolong Electric Drive Group Co., Ltd. Founded in 1984 and listed on the Shanghai Stock Exchange in 2002 (stock code: SH600580), Wolong has achieved massive global expansion through strategic acquisitions and technology integration.
Currently, the group operates 3 global manufacturing bases, 39 advanced factories, and 3 global R&D centers. Committed to a premier global brand strategy, Wolong's product catalog is highly integrated with the engineering DNA of internationally renowned centuries-old industrial brands, including Brook Crompton, Morley, Laurence Scott, Schorch, ATB, and OLI. This deep integration allows us to supply high-specification, specialized explosion-proof motors that drop directly into existing European infrastructure, minimizing downtime and engineering setup costs.
Combining world-class production capacity with European engineering standards to deliver optimal ROI.
Our collaborative R&D centers across Europe, Japan, and China continuously innovate on magnetic material optimization, reducing winding resistance and minimizing rotor slippage to achieve certified IE4 and IE5 efficiencies.
Motors are manufactured under strict ISO 9001 and ISO 14001 guidelines, and verified by major European third-party auditors like DNV, CSA, and Nemko to meet standard CE / ATEX compliance.
Benefiting from integrated local raw material supplies (premium silicon steels, high-density copper coils) and automated stator winding plants in China, we deliver high-spec equipment at rational price points.
A closer look inside the reliability and durability of our industrial explosion-proof electric motors.
The stator coil is crafted using premium polyester film and reinforced with glass cloth, utilizing either low-powder mica tape with high mica content or medium-powdered mica tape with an abundance of mica. Following the VPI (Vacuum Pressure Impregnation) process, a pristine white coil insulation structure is formed.
This strict manufacturing sequence guarantees exceptional electrical performance, high mechanical strength, complete resistance to moisture, and long-term thermal stability under cyclic loading conditions typical of mine hoist and conveyor operations.
The rotor features the classic squirrel cage design, utilizing high-efficiency cast aluminum or copper bars based on power requirements. Aluminum rotors are produced using centrifugal casting or advanced die-casting techniques, integrating the rotor bars and end rings into a solid single-piece construction.
For larger-capacity MV and HV motors, copper bar rotors are employed, featuring reliable mechanical bar securing and specialized end ring induction welding procedures. High-speed motors incorporate safety protective rings to ensure the copper bar configuration remains secure during high-rotation industrial processes.
The motor frame is designed using advanced structural and fluid multi-physics simulation platforms, optimizing thermal convection and mechanical stiffness. Built from high-strength cast iron (or steel plates for custom large machines), it offers generous structural safety margins and vibration isolation characteristics.
This design prevents resonance, absorbs high external shocks typical in mine crushers, and maximizes the heat-dissipation surface area to limit temperature rise under continuous duty cycles.
This assembly comprises the main cover, air guides, protective window, and a silencer plate. Engineered for low weight and stiffness, it minimizes vibration and windage noise. The side air inlet optimizes flow path behavior and limits turbulence, which drops overall acoustic emissions.
Equipped with an IP22 rating, the system guarantees safety by preventing physical contact with the fan blades while maintaining optimal thermal air circulation across the frame fins.
Combining legacy European engineering with Wolong's advanced manufacturing power.
To serve as a globally recognized drive manufacturer, Wolong has selectively acquired and integrated several historic industrial brands. Each brand brings specialized expertise to our production lines, creating an extensive catalog capable of meeting any project requirements in Spain.
With a 130-year history, Morley is synonymous with high-spec underground coal extraction drives. Laurence Scott supplies low-starting-current generators and drives for critical naval and nuclear power applications.
A leader in energy-efficient design, Brook Crompton brings more than a century of AC motor expertise to the Wolong group, including the premium 'W' and '10' series low-voltage and medium-voltage drives.
Established in 1882, Schorch delivers heavy duty drive technology for petrochemicals and pipeline systems. The inclusion of GE Industrial in 2018 further bolsters our high-voltage motor supply chains.
Our motors are tested and approved by the world's most rigorous safety and quality authorities.
Operating a heavy industrial or mining facility in Spain requires compliance with strict safety frameworks. Wolong's manufacturing plants hold comprehensive global certifications, allowing smooth transition, customs clearance, and local technical authorization across Spain and the broader European Union.

Addressing technical compliance, engineering compatibility, and supply chain questions.
Our motors cover Zone 1 and Zone 2 for gas hazards (typically Ex d, Ex db, or Ex eb protection) and Zone 21 and Zone 22 for combustible dust hazards (Ex tb or Ex tc protection). This makes them suitable for Spanish coal mines, chemical refineries, and agricultural silos.
Yes. Because Wolong acquired ATB, Brook Crompton, Morley, and Schorch, we retain the original manufacturing dimensions, shaft designs, and frame details. This allows us to supply direct drop-in replacements, minimizing installation downtime and modification costs.
We handle all documentation, including CE certification, ATEX certificates, and DNV approvals, and ship via major Spanish ports (such as Valencia, Barcelona, or Algeciras). Our engineering team assists with local compliance checks to ensure smooth integration.
PMSMs (such as our TBVF series) achieve IE5 efficiency, reducing energy losses by up to 30% compared to standard induction motors. This helps Spanish companies comply with national decarbonization targets (PNIEC) and significantly reduces operating costs.
