Uzbekistan is undergoing a rapid, multi-billion-dollar industrial transition. With major developments spanning the chemical complexes in Navoiy and Fergana, massive oil and gas processing at the Mubarek and Shurtan complexes, and intensive mineral extraction led by the Almalyk and Navoiy Mining and Metallurgy Combinats, safety and energy efficiency are paramount. These heavy sectors rely heavily on systems operating in environments where explosive gases, flammable vapors, and combustible dust mixtures are daily realities. Consequently, standard industrial AC motors are insufficient; the mandate for low-voltage, explosion-proof motors (such as those certified by EAC and ATEX) is a critical compliance and safety requirement.
Historically, Central Asian facilities relied on legacy Soviet-standard GOST motors. Modern operations, however, demand high-performance drives that optimize starting current characteristics, lower thermal footprint, and minimize energy consumption. Upgrading to IE3, IE4, and IE5 high-efficiency explosion-proof motors significantly mitigates risk. Selecting reliable China-based manufacturing giants such as Wolong ensures that projects receive components matching the highest European engineering standards while benefiting from the logistical connectivity of the Belt and Road rail routes.
Energy conservation has become a cornerstone of Uzbekistan's national industrial policy. According to state initiatives, heavy industries are mandated to modernize their auxiliary drive systems to lower grid strain and operating costs. Low-voltage explosion-proof motors running on continuous duty (S1) consume up to 90% of a plant's lifetime electric costs. Moving from obsolete efficiency standards to premium (IE3) or super-premium (IE4/IE5) high-efficiency motors delivers quantifiable returns:
Under the Wolong Electric Drive banner, several legendary century-old global motor and drive brands have been integrated to form a powerhouse of engineering capabilities, ensuring robust solutions for Uzbekistan's major operations:

A pioneer in electric motor technology with more than 110 years of history. Brook Crompton is renowned for energy-efficient motor designs and high-reliability "W" series drives, establishing a strong reputation for performance in harsh environments.
Germany's Schorch (est. 1882) is a benchmark for high-power, high-voltage drive systems in oil and gas, shipbuilding, and water treatment. In the vibration field, OLI Brand stands as a global leader in high-performance vibration motors (MVE) and explosion-proof vibration sensors.
Additionally, in 2015, Nanyang Explosion-proof Group Co., Ltd. (CNE)—China's largest explosion-proof motor research and manufacturing base—joined Wolong Group. This integration combined top-tier scientific expertise in flameproof, increased safety, dust ignition-proof, and positive pressure motors, which are widely utilized across global petrochemical and mining complexes. In 2018, the commercial and industrial division of General Electric (GE) Motors joined the alliance, bringing further experience in heavy industrial drives to support heavy metallurgical, chemical, and cement projects in Uzbekistan.
Our explosion-proof low-voltage motors are fully certified to meet international and local Eurasian compliance standards, facilitating smooth commissioning in Uzbekistan.
By complying with ISO 9001, NEMA, IECEx / ATEX, and EAC (CU-TR) requirements, our low-voltage motors are fully authorized for operation across Eurasia. In addition, the acquisition of the TESTSAFE certification (the premier coal mining equipment certification body in the Southern Hemisphere) validates our designs for underground environments, ensuring high reliability in deep mine shafts and heavy-duty coal transport networks.
Designed for extreme durability, low noise levels, and explosion protection under continuous heavy loads.
Our squirrel-cage rotors are constructed with cast aluminum utilizing advanced centrifugal or die-casting techniques. Molten pure aluminum is injected into the rotor core slots under pressure, creating a single integrated component that combines the rotor bars and end rings. This design minimizes internal resistances and enhances structural integrity.
For high-capacity low-voltage industrial drives, copper bar rotors are utilized, featuring secure mechanical bar placement and reliable end-ring welding. A high-speed protective retaining ring design ensures safe, stable rotation under variable load conditions.
Stator coils are wrapped with premium polyester film and reinforced with glass cloth, using high-mica content tapes. The wound stators undergo a Vacuum Pressure Impregnation (VPI) cycle, curing into a dense, solid insulation system.
This process eliminates air gaps, providing excellent moisture resistance, high dielectric strength, and thermal stability (Class F/H rating). It ensures long-term operational reliability in wet, dusty, or chemically corrosive atmospheres.
The motor frame is designed using digital multi-physics simulation software to optimize structural rigidity, magnetic flux distribution, and heat dissipation. Constructed from high-tensile cast iron, the frame features robust cooling fins that maximize air-to-surface heat transfer.
The structural design offers high mechanical redundancy, allowing it to withstand high shock loads and isolate resonant frequencies. This ensures low vibration levels and maintains internal clearances to prevent frictional sparking.
The ventilation system consists of an engineered fan cover, an air-guide cylinder, protective mesh, and a sound-damping silencer plate. The side-entry air intake design optimizes airflow around obstacles behind the motor, reducing aerodynamic turbulence and noise generation.
Sound-absorbing linings are integrated inside the shroud to dampen high-frequency operational noise. The assembly meets IP22 protection guidelines, preventing accidental contact with rotating parts while allowing high cooling airflow.
