Engineered to comply with local industrial requirements, offering maximum uptime in phosphate extraction, processing, and marine applications.
Decarbonization, safety compliance, and robust reliability in extreme conditions
Morocco is rapidly positioning itself as a dominant economic powerhouse and manufacturing hub bridging Europe and Africa. Key sectors, including chemical processing, maritime transportation, port infrastructure, and particularly phosphate mining (managed by the state-owned OCP Group), demand heavy-duty rotating machines that can operate reliably under harsh environmental conditions. The Atlantic and Mediterranean coastal chemical complexes at Jorf Lasfar and Safi require industrial equipment that can withstand highly corrosive saline air and chemical vapors. Similarly, phosphate extraction at sites such as Khouribga, Benguerir, and Youssoufia requires electric motors with premium IP codes and dust-ignition proof designs to prevent hazardous dust explosions.
At Shaanxi Nanfang Motor Technology Co., Ltd, as the authorized distributor of Wolong Electric Drive Group, we specialize in supplying high-performance AC High Voltage Explosion-Proof Motors tailored specifically for Morocco's unique environmental challenges. With the global transition toward energy efficiency and safety in hazardous atmospheres, our heavy-duty motors deliver superior protection, complying with European ATEX, international IECEx, and local Moroccan standards (NM conformity guidelines administered by IMANOR).
Morocco holds over 70% of the world’s phosphate reserves. Our high-voltage motors power heavy slurry pumps, grinding mills, rotary kilns, and vast conveyor networks. They are designed to withstand abrasive phosphate dust and thermal shock.
Industrial coastal complexes like Jorf Lasfar require anti-corrosive coatings (C5-M class according to ISO 12944) and internal anti-condensation heating elements to prevent failure from highly saline Atlantic humidity.
Morocco is investing heavily in green hydrogen and green ammonia synthesis. Synthesis plants require explosion-proof positive pressure (Ex p) and increased safety (Ex e) motors to safely manage hydrogen, classified under Gas Group IIC.
A Global Leader in Rotating Machines, Control Systems, and Industry Integrations
Shaanxi Nanfang Motor Technology Co., Ltd is the authorized distributor of Wolong. Wolong Electric Drive Group Co., Ltd was founded in 1984 and successfully listed on the Shanghai Stock Exchange in 2002 (code SH600580). Over more than 30 years of sustainable growth, Wolong has developed 3 primary manufacturing bases, 39 manufacturing factories, and 3 state-of-the-art research and development centers globally.
By executing a focused global brand strategy, Wolong has established itself as an international market leader in R&D, manufacturing processes, quality control, and after-sales services for electric motors and drive control systems.
Providing Morocco's industries with the combined technology of the world's most trusted manufacturers.
In 2011, Wolong acquired a 97.94% stake in the Austrian ATB Group, one of Europe's top three motor manufacturers. This acquisition brought the historic brands Morley and Laurence Scott into the family. Morley has nearly 130 years of expertise in underground mining motors, making it highly valued in the global coal and phosphate markets for quality and reliability. Laurence Scott is a pioneer in low-starting-current motors for nuclear power stations and naval vessels, having won the Queen's Award for three consecutive years.
Brook Crompton has over a century of experience in motor design and innovation, leading the development of highly energy-efficient low, medium, and high-voltage AC motors. This includes the premium "W" and "10" series, which operate reliably in harsh, hazardous industrial environments. Schorch, founded in Germany in 1882, has set industry standards for heavy drive systems used globally in oil, gas, chemical processing, wastewater management, steel manufacturing, and tunnel construction.
In 2015, CNE, China's largest explosion-proof motor research and production base, officially joined Wolong Group. This integration expanded the group's range of low-voltage and high-voltage Ex motors for oil, chemical, and nuclear power projects. In 2018, Wolong partnered with General Electric (GE) Industrial Motors. GE's experience in heavy-duty design for mining, power generation, and water treatment further strengthened Wolong's product engineering capabilities.
Deep dive into the structural materials and design of our high-voltage explosion-proof motors
Our rotors feature a rugged squirrel cage design. For smaller to medium frame sizes, cast aluminum rotors produced via centrifugal casting or high-pressure die-casting are used. Molten pure aluminum is poured into the slots of the rotor core, creating a single-piece construction that integrates the rotor bars and end rings. This design provides reliable torque transmission and mechanical stability.
For larger capacity, high-voltage motors, copper-bar rotors are utilized. The copper bars are secured into the rotor slots and welded to the end rings. Additionally, high-speed motors feature high-strength alloy retaining rings to prevent centrifugal deformation of the rotor winding end structure.
The stator coil is wrapped with polyester film and reinforced with glass cloth. We use low-binder mica tape with a high mica content or medium-powdered mica tape. The fully wound stator undergoes our Vacuum Pressure Impregnation (VPI) process. VPI ensures that varnish penetrates deep into all winding layers, eliminating air pockets and moisture entry.
This process provides high dielectric strength, moisture resistance, mechanical rigidity, and thermal stability (conforming to Class F insulation with Class B temperature rise, or Class H for highly demanding duties).
The motor frame is designed using digital multi-physics simulation platforms to model fluid dynamics, vibration profiles, and structural stress. Built from high-grade cast iron or fabricated structural steel, the frame has thick walls that can withstand internal gas explosions without risk of rupture (specifically for Ex d flameproof enclosures).
Deep external cooling fins optimize heat dissipation in hot Moroccan climates. The design also isolates natural frequencies to prevent resonance and keep vibration levels well within IEC limits.
The low-noise ventilation system consists of an aerodynamic fan cover, air guide cylinder, protection window, and silencer plate. The side-entry air inlet bypasses obstacles behind the motor, reducing pressure drop and ventilation noise.
Integrated acoustic absorption materials help lower overall noise levels during operation. The system holds an IP22 rating, preventing accidental contact with the rotating fan blades.
High-precision testing ensures every motor meets international safety standards
Compliance is the foundation of electrical safety in explosive atmospheres
Our motors are manufactured under a strict global quality system. They hold certifications that allow them to be integrated directly into industrial plants in Morocco without additional barriers:
Supplementary drive models designed for auxiliary applications in Moroccan mining and logistics systems
How Shaanxi Nanfang Motor and Wolong are preparing for the future of Moroccan smart industries
As Morocco advances its Industrial Acceleration Plan, modern manufacturing facilities are shifting toward digitalization and automation. To support this transition, our medium and high-voltage motors are moving toward smart, connected designs. Integrating real-time IoT vibration and temperature sensors allows plant operators to monitor motor health from a centralized control room, reducing unplanned downtime in critical sectors like chemical refining and phosphate processing.
Additionally, we are expanding our focus on efficiency, offering permanent magnet synchronous motors (PMSM) alongside standard induction designs. By combining these high-efficiency motors with variable frequency drives (VFD), plants can optimize energy consumption during fluctuating loads—such as in variable-speed pumping or conveyor networks. This technology supports Morocco's national energy strategy, which targets reducing industrial carbon footprints and optimizing overall resource efficiency.
