The Slovak Republic, positioned as a central European industrial powerhouse, maintains a highly demanding mineral extraction, processing, and heavy civil construction sector. From the deep magnesite operations in Jelšava and Lubeník to the complex brown coal deposits in the Upper Nitra region, Slovakia’s geological parameters present high ambient humidity, elevated levels of abrasive mineral dust, and explosive gas mixtures (methane and combustible dusts). Furthermore, major tunnel building projects across the Slovak Carpathian ranges require massive, highly reliable infrastructure drives.
To safely navigate these hazards, Slovak mine operators require electric drive platforms engineered with certified explosion-proof casings, optimized torque curves, and strict compliance with European safety legislation. Operating under severe environmental profiles dictates that every rotor assembly, stator winding, and cooling shroud must deliver maximum operational efficiency and thermal endurance. Our high-voltage and low-voltage electric motor ranges provide custom engineering solutions for Slovak mine conveyors, ventilation systems, water drainage systems, and shearers.
High-output explosion-proof drives engineered for continuous conveyor transport and coal mining extraction equipment under ATEX specifications.
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 in 2002 (code SH600580). Over decades of systematic expansion, Wolong has built 3 key manufacturing bases, 39 advanced factories, and 3 global R&D centers. Concentrating on high-precision electric motor manufacturing and digital control drive systems, Wolong executes a multi-brand strategy that positions it at the leading edge of global technology, R&D, and industrial sales.
In 2011, Wolong acquired a 97.94% controlling stake in the Austrian ATB Group (ATB Motor), incorporating historic brands such as Morley (nearly 130 years of underground coal mining expertise) and Laurence Scott (low-starting-current naval/nuclear class systems). This was followed by the integration of Brook Crompton Motors (pioneers of energy-efficient industrial AC motors), Schorch (founded in 1882, providing heavy petrochemical/gas systems), OLI (vibration technology market leader), Nanyang Explosion Protection Group (China's leading explosion-proof base), and a strategic partnership with General Electric (GE) industrial motors in 2018.
Our industrial mining motors are designed utilizing multiphysics simulation software to guarantee stable operation, explosion safety, and low vibration levels.
Features squirrel cage design configurations, utilizing centrifugal cast aluminum or die-casting techniques. The molten pure aluminum is poured under high pressure into the laminated rotor core slots, integrating rotor bars and end rings. For large-capacity drives, copper bar rotors are dynamically balanced and joined using advanced end-ring welding procedures. This structural redundancy prevents copper bar detachment under high start-up torque loads.
Our stator coils are insulated with high mica-content tapes reinforced with polyester film and glass cloth. Following precise winding insertion, the entire stator core undergoes Vacuum Pressure Impregnation (VPI) with premium thermosetting resins. This chemical treatment seals the windings, providing high mechanical strength, resistance to chemical moisture, and class-leading thermal insulation margins.
Engineered using 3D structural and fluid simulation programs, the heavy-duty cast iron (or structural steel) frame features deep cooling ribs for optimized thermal heat dissipation. The frame structure provides generous natural frequency isolation margins, allowing the motor to absorb extreme shock loads and operate with exceptionally low vibration amplitudes under rough underground mining conditions.
Consists of a custom aerodynamic fan cover body, internal air guide cylinders, protective windows, and acoustic silencer lining. The air intake is positioned on the side to optimize air flow paths, preventing debris from blocking ventilation. Sound-absorbing materials inside the hood reduce windage noise. The IP22 system prevents accidental contact with the rotating fan blades.
Integrating historic European electric machine brands to create a comprehensive and unified product portfolio for mining, oil & gas, and heavy manufacturing.
Acquired in 2011, Austrian-based ATB group is a cornerstone of European industrial drive engineering. Under ATB, Morley boasts nearly 130 years of history dedicated to the underground coal mining sector. Known for ruggedness, high torque margins, and reliability, Morley flameproof drives are globally recognized as the standard for high-performance extraction machinery.
Laurence Scott is legendary for pioneering low-starting-current motors for critical sectors like nuclear power stations and marine generators. Schorch (founded in 1882 in Germany) provides high-voltage drive systems for gas, petrochemical, and municipal water management. Together, they represent unmatched electrical engineering and process-safety expertise.
Nanyang Explosion Protection Group (CNE), China's premier explosion-proof research and manufacturing base, joined Wolong in 2015, integrating specialized designs for explosive gas and dust hazards. Brook Crompton, with over a century of experience, is at the forefront of high-efficiency motor designs, providing complete sets of energy-efficient low and medium voltage systems.

Our comprehensive international certification strategy enables smooth integration with Slovak heavy industry projects:
Providing highly specialized drive systems designed to withstand the harsh, dusty, and wet conditions of heavy processing plants, mining shafts, and tunnels.
High start-up load capacity requires motors with high pull-up torque and specialized cooling configurations. Our flameproof synchronous and asynchronous motors deliver steady torque profiles, ensuring continuous operations across steep underground slopes.
To handle high flow rates, dewatering drives must withstand constant dampness and high humidity. Our YBRB series flameproof water pump motors are engineered with IP55/IP66 enclosure protection to operate reliably in underground wet sumps.
Designed for continuous operation under S1 duty cycles. Wolong's variable frequency speed regulation systems adjust airflow dynamically based on real-time gas monitoring data, reducing overall industrial energy consumption.
Industry 4.0 is reshaping European industrial operations. Traditional induction drives are evolving into smart, connected devices that feature integrated multi-physics sensors. Our technical roadmap for the Slovakia market focuses on three key areas:
Our complete range of low, medium, and high-voltage industrial drives designed to deliver high reliability under harsh operational environments.

Under Slovak mining safety guidelines and European Union legislation, all electric motors deployed in potentially explosive atmospheres must have ATEX directive (2014/34/EU) and IECEx certification. For underground environments with high methane levels, motors must meet the 'Ex d I Mb' or 'Ex de I Mb' classifications. Sh陕西南方电机 (Nanfang Motor Tech) provides comprehensive certificates issued by notified bodies such as Nemko and TestSafe, verified by Technická inšpekcia.
Yes, our YBBP water-cooled and TBVF permanent magnet synchronous motors are specifically engineered for VFD operation. These motors feature reinforced insulated windings and vacuum pressure impregnation (VPI) treatment to handle voltage spikes, along with insulated bearings to prevent EDM (Electrical Discharge Machining) currents.
Water cooling provides superior thermal management compared to traditional air-cooled motors, keeping operating temperatures low even in high-ambient-temperature environments like deep shafts. This prevents thermal degradation of the stator windings and ensures reliable performance under continuous load conditions.
Standard industrial motors can typically be shipped within 8 to 12 weeks. Custom high-voltage motors requiring engineering modifications (e.g., custom shaft dimensions, specialized mountings, or specific ATEX certifications) generally have a lead time of 16 to 22 weeks. Deliveries are coordinated via major European sea and rail networks directly to Slovak project sites.
Our design process utilizes finite element analysis (FEA) to simulate structural and fluid dynamics. Motor frames are cast from high-strength iron with integrated structural ribs to absorb mechanical vibrations. Dynamic balancing of the rotor assemblies ensures overall vibration levels remain well within ISO 10816 standards.
