Engineered for extreme operating environments, certified for Russian industrial applications and heavy manufacturing.
We are the authorized B2B distributor of Wolong Electric Drive Group Co., Ltd (established in 1984, listed on the Shanghai Stock Exchange under code SH600580). Over nearly four decades of strategic growth, Wolong has consolidated its position as a global leader in electric motor design, operating 3 global manufacturing bases, 39 advanced factories, and 3 R&D institutes across the world.
Our partnership delivers an unmatched portfolio of explosion-proof and high-voltage motors to heavy industries across Russia, Central Asia, and the CIS region. By leveraging the combined engineering strengths of domestic pioneers and heritage European manufacturers acquired by Wolong, we offer unparalleled motor customization, absolute compliance with GOST / EAC regulations, and the technical resilience required for operations from cold Siberian terrains to remote Arctic offshore platforms.
Understanding operational realities, environmental parameters, and energy transitions in the Russian Federation.
Industrial operations in the Russian Federation—spanning oil extraction in Western Siberia, coal mining in the Kuznetsk Basin (Kuzbass), and metal processing in the Urals—require electric drives that operate reliably under extreme conditions. The primary challenges are temperature fluctuations, with design minimums down to -60°C, and dust-choked, highly explosive atmospheres containing methane and combustible gases.
Standard electric motors fail due to brittle shafts, compromised lubrication, and insulation degradation in cold-start scenarios. Our custom motor configurations feature specialized low-temperature carbon steel/alloy shafts, automatic space heaters to prevent internal condensation, and specialized synthetic grease that retains viscosity at sub-zero temperatures. These details ensure continuous operation and minimize unplanned downtime in Russian mineral extraction and processing plants.
With western manufacturers exiting the Russian market, industrial enterprises face procurement challenges for replacement drives and new capital projects. B2B purchasing agents now require partners who can supply reliable, high-spec alternative drives that fit existing foundations without needing expensive civil engineering reworks.
Through Shaanxi Nanfang Motor and the Wolong Group, Russian procurement departments gain access to a direct supply of heavy-duty AC drives. These systems match or exceed the frame standards and electrical specifications of legacy European components. Our engineering team specializes in retrofitting projects, adjusting shaft extensions, terminal box orientations, and foot-mounting dimensions to seamlessly integrate into existing industrial networks.
Providing optimal torque control, high thermal capacity, and specific certification pathways.
How strategic acquisitions bring specialized global industrial motor design to Russian enterprises.
By acquiring major European and domestic brands, Wolong has integrated centennial motor research and development capabilities into its standard manufacturing processes. When sourcing from Shaanxi Nanfang Motor, clients receive products that combine global manufacturing efficiency with highly specialized industrial heritage.
Acquired in 2011, Austria's ATB is a leading European motor developer. The Morley brand brings over 130 years of underground coal mining expertise, producing flameproof and heavy-conveyor drives recognized for durability and reliability in dangerous mining zones.
Dating back to 1882 in Germany, Schorch sets high standards for heavy-duty drive systems in oil, gas, and power generation. Laurence Scott provides low-starting-current motor designs, historically supplied to nuclear facilities and heavy naval vessels.
The acquisition of GE's medium and high-voltage industrial motor division enhanced Wolong's design capabilities for chemical and processing industries. Alongside OLI's global leadership in vibration motor technologies, we deliver specialized drive solutions for complex setups.
Premium components designed for maximum durability and thermal isolation under challenging conditions.
Utilizes squirrel-cage construction with cast-aluminum or copper-bar configurations. Cast aluminum rotors are produced using centrifugal or die-casting techniques for a single-piece design that integrates rotor bars and end rings. Copper-bar rotors feature secure bar placement and welded end rings, reinforced with alloy retaining rings to withstand high centrifugal forces in high-speed, variable-frequency drives.
Coils are insulated with polyester film and glass cloth tape containing premium mica content. The entire assembly undergoes Vacuum Pressure Impregnation (VPI) with solventless resins, followed by thermal curing. This process eliminates micro-voids, providing protection against moisture, chemicals, and mechanical vibrations while ensuring high dielectric strength.
Manufactured from high-strength cast iron (HT250/HT300) and engineered using multi-physics structural and fluid simulation software. The frame design features optimized cooling fins for heat dissipation and robust mounting feet to absorb mechanical shock. Rigidity limits structural resonance and keeps motor vibration levels within safe limits.
Features an aerodynamic fan cover with built-in air guides, protective grilles, and noise-damping internal linings. Side-entry air intakes minimize negative impacts from rear obstructions. Rated to IP22/IP55, the hood prevents foreign particles from contacting the fan blades while maintaining cooling air velocity across the frame.
Deploying electrical machinery in hazardous zones within the Eurasian Economic Union (EAEU) requires strict compliance with Technical Regulations. All explosion-proof motors supplied by Shaanxi Nanfang Motor hold valid CU-TR 012/2011 (safety of equipment in explosive environments) and CU-TR 004/2011 (low-voltage safety) certificates.
Our motors display the EAC mark on their nameplates. The terminals, cable glands, and flameproof enclosures comply with GOST R IEC 60079 standards. This ensures smooth registration of dangerous industrial objects (OPO) with Rostekhnadzor and simplifies the local engineering inspection processes.

How our team adapts motor parameters to match existing site electrical and physical requirements.
Custom stator winding insulation prevents voltage spikes when powered by variable frequency drives. Optional insulated bearings (e.g., SKF hybrid bearings) on the non-drive end prevent shaft currents, avoiding bearing wear and extending maintenance intervals.
Flameproof (Ex d), increased safety (Ex e), non-sparking (Ex nA), and pressurized (Ex p) enclosures conform to safety requirements for gas zones 1 and 2, and dust zones 21 and 22. Enclosures utilize weather-resistant coatings and corrosion-proof hardware.
Specialized shaft dimensions, double shaft extensions, high-strength alloy steels, and custom flange sizes (DIN/NEMA/GOST standards) simplify installation. Standard monitoring includes PT100 temperature sensors and vibration sensors.
