High-specification motor solutions optimized for the unique requirements of the Sines Petrochemical Complex, Matosinhos Maritime Logistics, and Portugal's growing aquaculture and offshore energy industries.
As Portugal aggressively positions itself as a European green energy pioneer, the industrial and commercial sectors are undergoing a significant structural shift. Key hubs such as the industrial cluster of Sines, the manufacturing zones around Porto, and the processing plants in Lisbon demand highly efficient, intrinsically safe industrial motors. This transition is heavily supported by the Portuguese government's commitment to industrial decarbonization under the PRR (Recovery and Resilience Plan).
Traditional industries like pulp and paper (driven by giants like The Navigator Company and Altri), heavy metallurgy, chemical refining (Galp Energia), and mineral processing are replacing obsolete, energy-intensive motors with next-generation variable-frequency drive (VFD) systems and permanent magnet synchronous motors (PMSM). These technologies are essential to reduce operational expenses (OPEX) under the EU's stringent Carbon Border Adjustment Mechanism (CBAM) and energy efficiency directives.
Demands ATEX and IECEx Zone 1 / Zone 2 certified positive pressure and flameproof high-voltage motors to handle volatile environments safety.
Requires high-efficiency IE4/IE5 motors and dust-ignition proof designs (IP65/IP66) to ensure continuous operation in challenging ambient conditions.
Calling for severe-duty marine-grade motors and electric propulsion systems to fulfill Port of Sines and Port of Lisbon decarbonization mandates.
Shaanxi Nanfang Motor Technology Co., Ltd. is the official authorized distributor of Wolong. Wolong Electric Drive Group Co., Ltd., founded in 1984 and listed on the Shanghai Stock Exchange in 2002 (code SH600580), has grown to become the world's leading manufacturer of electric motors and drive control systems.
With 3 massive manufacturing bases, 39 state-of-the-art factories, and 3 global R&D centers in China, Europe, and Japan, Wolong leads the motor sector in technological innovation, raw material quality, and global deployment capability. By blending century-old European brand heritage with cutting-edge production scales, we supply tailored motor solutions across 58 countries.
Through strategic acquisitions of the world's most prestigious and historic motor manufacturers, Wolong has unified centuries of engineering excellence under a single global supply chain.
Wolong acquired 97.94% of the Austrian ATB Group, one of Europe's top three motor manufacturers. This brought the legendary British mining brand Morley (boasting a 130-year legacy of explosion-proof conveyor and pump motors) and Laurence Scott (renowned for low-starting-current generators and naval propulsion) into the group.
Schorch (Germany, Est. 1882) joined Wolong, establishing standards in heavy-duty oil & gas drive systems. Concurrently, Brook Crompton Motors integrated its specialized century-old knowledge in manufacturing energy-efficient low, medium, and high-voltage AC motors (Premium "W" and "10" series) for extreme chemical environments.
China's premier explosion-proof motor research and manufacturing base, Nanyang Explosion-Proof Group (CNE), joined Wolong to scale up ATEX/IECEx certified safety lines. This complemented our global joint venture with OLI, the undisputed leader in vibration motors (MVE series) and Ex vibration sensors.
Wolong acquired General Electric's (GE) commercial and industrial motor division. This integration added heavy industrial legacy and advanced mechanical platform technologies serving global sectors: water treatment, cement, refining, and mining.
Every Wolong motor is designed using advanced multi-physics digital simulation platforms to ensure mechanical longevity, optimal thermal dissipation, and safety in hazardous zones.
Centrifugal aluminum casting and high-conductivity copper bar options ensure robust starting torque. Precision dynamic balancing minimizes mechanical vibration, protecting bearing lifespans.
Utilizes high-mica low-powder tape wrapped around copper windings. Submerged in high-grade varnish via Vacuum Pressure Impregnation (VPI) to resist moisture, oil, and chemical vapor ingress.
Optimized using Finite Element Analysis (FEA) to maximize surface heat dissipation. High-strength cast iron structures withstand severe shock loads and prevent resonance amplification.
Features integrated air guides, silencer plates, and sound-absorbing structures. Side-entry ports minimize airflow obstructions, reducing drag noise and ensuring IP22/IP55 compliance.
We ensure rapid market entry and compliance with the safety directives of various target jurisdictions through rigorous testing and international approvals.

Our regulatory strategy guarantees that heavy electrical machinery can operate across global territories:
Explore our comprehensive catalog of high-efficiency asynchronous, explosion-proof, and variable-frequency motors engineered to keep your processes running smoothly.
YZYKK and YZYKS positive pressure type motors rely on a pressurized enclosure to prevent ambient explosive gas mixtures from entering the motor interior. The positive internal pressure is maintained using clean air or inert gas, making them suitable for hazardous Zone 1 and Zone 2 environments (especially in Group IIB/IIC configurations). This configuration provides high thermal margins, minimized noise levels, and robust safety margins for Sines Refineries and petrochemical storage hubs.
Permanent Magnet Synchronous Motors (like the WEPM series) provide significant efficiency improvements over traditional induction motors, even under partial load conditions. In continuous pulp production plants, VFD speed regulation paired with PMSM motors directly reduces heat losses and power grid demands, leading to a rapid return on investment (ROI) within 12–18 months of operation.
The 40kW marine electric outboard is certified to meet CE standards, with components designed to IP67/IP68 ingress protection ratings. Cast from corrosion-resistant marine alloys with sacrificial anodes, it is optimized to withstand salt spray and harsh marine environments, making it ideal for Portugal’s coastal estuary vessels and aquaculture initiatives.
Vacuum Pressure Impregnation (VPI) replaces air voids within the stator windings with a dense, cured resin. This prevents the entry of moisture, salt mist, and acidic/alkaline particulates, ensuring long-term insulation reliability and high dielectric strength for coastal industrial installations.
