Premium Explosion-Proof, High-Voltage & Permanent Magnet Synchronous Motors Tailored for Azerbaijan's Demanding Industrial Sectors
Azerbaijan stands as the pivotal economic engine of the South Caucasus, currently undergoing a historic structural transformation. While the nation’s legacy lies in the massive oil and gas reserves of the Caspian basin—spearheaded by the State Oil Company of Azerbaijan Republic (SOCAR)—the government's active diversification policies are rapidly accelerating developments in metallurgy, underground ore mining, and chemical processing. Key projects in the Dashkasan iron ore zone and the gold-rich deposits of Gedabek have generated unprecedented demands for heavy-duty extraction and conveyor equipment.
Operating in Azerbaijan requires mechanical systems capable of enduring both the extreme ambient temperatures of the dry Kura-Aras Lowland and the high-altitude, high-dust environments of the Lesser Caucasus mountains. Furthermore, the oil, gas, and refining clusters in Baku and Sumgait mandate strict explosive safety standards (ATEX, IECEx, EAC). As standard off-the-shelf industrial motors struggle to cope with these combined challenges, premium explosion-proof electric motors—integrating advanced thermal management and robust mechanical frames—have become critical assets for local operators seeking minimal downtime and optimized operational expenditure.

Shaanxi Nanfang Motor Technology Co., Ltd is the premier authorized distributor of Wolong (Wolong Electric Drive Group Co., Ltd). Founded in 1984 and listed on the Shanghai Stock Exchange in 2002 (code SH600580), Wolong has grown to become a world-renowned leader in the electric drive industry. Through decades of strategic growth, Wolong now commands 3 manufacturing bases, 39 factories, and 3 global R&D centers, building a unified network that spans across China, Europe, and the Americas.
A key aspect of Wolong’s global strength lies in its portfolio of historic, century-old European motor brands. In 2011, Wolong acquired 97.94% of the Austrian ATB Group, which brought under its banner legendary industrial names such as Morley (renowned for underground mining motors with 130 years of history), Laurence Scott (pioneers in low starting current naval and nuclear power motors), and Schorch (established in 1882, setting standards in heavy duty gas and water utility drives). By integrating these legacy brands with Brook Crompton, OLI vibration technology, the Nanyang Explosion-Proof Group (CNE), and the commercial/industrial motor division of General Electric (GE), Wolong has solidified its status as an unmatched powerhouse of motor technology and high-end engineering.
The global heavy industry sector is undergoing a profound transition toward high energy efficiency and digitized preventative maintenance. In the context of Azerbaijan, where the cost of industrial power is steadily adjusting to meet global economic standards, minimizing energy loss is paramount. The technology roadmap for Azerbaijani mining and oil & gas operations revolves around three main pillars:
Transitioning from older legacy motors to IE4 and IE5 permanent magnet synchronous motors (PMSM). These systems reduce electrical consumption by up to 15% and offer high torque characteristics even at lower rotational speeds.
Integrating vibration and temperature sensors (such as OLI Ex sensors) directly into the motor frames. This enables operators in remote locations like the Lesser Caucasus to monitor motor health in real-time, preventing catastrophic failures.
Utilizing high-mica content tape combined with modern VPI (Vacuum Pressure Impregnation) processes. This guarantees thermal stability class H and prevents moisture ingress, which is vital in high-humidity oil refineries.
By prioritizing the adoption of permanent magnet variable frequency speed regulation systems (such as the WEPM and TBVF series), industrial plants in Baku, Sumgait, and Ganja can achieve rapid return on investment. The ability to run motors continuously under variable load conditions without sacrificing power factor is a game-changer for heavy water pumps and ventilation systems.
Petrochemical processing demands absolute reliability and strict explosive containment. Motors operating in these zones must be engineered to prevent gas or dust ignition. Our range of high-voltage explosion-proof motors (such as the YB3 and YZYKK positive-pressure shell types) provides class-leading security. Features include flameproof enclosures designed to withstand internal explosions without propagating flames to the surrounding atmosphere, IP55/IP66 ingress protection, and chemical-resistant coatings to prevent degradation from corrosive gases.
In dust-heavy, high-vibration mining sites, mechanical durability is key. For bulk material handling, we supply specialized conveyor motors like the YBSS and YBSD series, optimized to deliver high starting torque under full load. These motors utilize high-tensile cast iron frames and dynamically balanced copper bar or cast aluminum rotors. This prevents shaft deformation under extreme mechanical stress and ensures continuous conveyor operation across kilometers of rugged terrain.
Water distribution and wastewater processing across Azerbaijan's municipal zones require highly efficient pumps running 24/7. The YBRB flameproof water pump motors represent the pinnacle of fluid-drive engineering. Designed to couple seamlessly with high-flow pumps, these asynchronous motors feature water-cooled options to keep running temperatures low, extending bearing life and minimizing maintenance intervals in remote pump stations.
By leveraging Wolong's state-of-the-art manufacturing plants in China, Shaanxi Nanfang Motor provides Azerbaijani clients with unmatched supply chain resilience and quality assurance. The Nanyang explosion-proof production facilities utilize digital twin technology, allowing engineers to simulate structural load and thermal stress on a virtual model before the motor ever reaches the physical assembly line.
Every step of the manufacturing process is automated to ensure consistent precision:
Traditional European supply chains are currently plagued by long lead times and high energy surcharges. Our integrated supply chain combines century-old European engineering design (ATB, Schorch, Morley) with the rapid manufacturing speed and cost efficiency of China's automated factories. The result is a premium-grade product delivered in half the time of conventional suppliers, backed by a robust global warranty.
Entering the Azerbaijani market requires navigating local standards managed by the Azerbaijan Standardization Institute (AZSTAND). For hazardous environments, the requirements are particularly strict. Our products come fully prepared with international safety certifications, smoothing the importation and commissioning process:
Nemko / ATEX
CSA Standards
CE Conformity
CC Certificate
SABS Standard
TESTSAFE
By offering products certified under both the European ATEX directives and Eurasian EAC (GOST-R/GOST-K equivalent) frameworks, we ensure that Azerbaijani industrial installations remain compliant with all state safety inspection protocols. Shaanxi Nanfang Motor also provides dedicated localization support, including comprehensive technical data sheets, installation manuals in Russian and English, and remote engineering consultations during the installation and testing phases.
Our rotors feature premium squirrel cage designs, using high-purity cast aluminum or heavy-duty copper bars. Cast aluminum rotors are produced using centrifugal casting or advanced high-pressure die-casting, forming a seamless, integrated component with the rotor bars and end rings. For high-output applications, copper bar rotors are secured with premium end ring welding procedures. High-speed models are further reinforced with alloy protective rings, ensuring mechanical integrity and dynamic balance under variable load pressures.
The stator coil is built with glass-reinforced polyester film and high-quality, high-mica tape. The complete stator assembly undergoes the VPI (Vacuum Pressure Impregnation) process, converting the raw winding into a solid, moisture-resistant block. This state-of-the-art winding insulation provides exceptional dielectric strength, superior moisture isolation, high thermal conductivity, and structural rigidity against electromagnetic vibrations.
The motor housing is developed using advanced fluid and structural multi-physics finite element analysis (FEA). Cast in high-strength cast iron (with structural steel available for custom requests), the frame incorporates structural safety margins, optimal surface area cooling fins, and vibration isolation properties. This enables the motor to withstand high mechanical shocks and keep temperature rises well below standard limits.
Comprising a rigid fan cover body, air guide cylinder, protective window, and acoustic silencer plate, this system optimizes cooling airflow while dampening acoustic output. The side air inlet geometry mitigates ventilation obstacles close to the motor body, reducing noise caused by turbulences. The system carries an IP22 rating, preventing accidental contact with the rotating fan blades.
For installations in Azerbaijan (specifically onshore and offshore petrochemical projects under SOCAR supervision), motors must comply with international explosion-proof standards, primarily ATEX or IECEx. Additionally, since Azerbaijan has close economic ties within the regional markets, TR CU (EAC) certification is widely accepted and often preferred. Our Wolong and ATB series motors hold all these certificates, ensuring compliance and smooth customs clearance at the Port of Baku.
High altitudes lead to thinner air, which reduces the cooling efficiency of standard self-ventilated motors. Operating at elevations above 1000 meters in the Lesser Caucasus requires engineering adjustments, such as thermal derating, upgraded insulation (Class H), or active liquid cooling systems (as in our YBBP series). Shaanxi Nanfang Motor conducts altitude-specific thermal calculations to ensure your motor does not overheat under full mechanical load.
Shipments typically depart our centralized distribution centers in China and travel via the Middle Corridor (Trans-Caspian International Transport Route) rail freight, arriving in Baku within 15 to 25 days. For heavy industrial projects, sea-rail multimodal transport is also available. Shaanxi Nanfang Motor provides full customs clearing documentation, cargo insurance, and tracking updates throughout the transit process.
PMSM motors (such as the TBVF and WEPM series) offer significant benefits: they maintain high torque at low speeds, operate with superior efficiency (IE4/IE5), and have a high power factor. In conveyor applications where high starting torque is required to move heavy ores, PMSM systems prevent high current draw during startup, reducing wear on electrical grids and lowering overall energy costs.
We provide remote commissioning support, complete 3D CAD step files, detailed electrical schematics, and testing documentation in Russian and English.
