A deep-dive technical overview of local application scenarios, harsh ambient climates, and geological challenges.
Kazakhstan's massive mining sector serves as a global cornerstone for raw mineral supply. From the extensive Karaganda coal deposits to the high-yield copper operations of Kazakhmys and KAZ Minerals, and the vast chromite complexes in Aktobe, the demands placed on mechanical systems are uniquely severe. Operating within these terrains requires electric motor machinery that complies fully with Eurasian Customs Union (EAC Ex / CU-TR) standards and can withstand extreme thermal ranges from -45°C in winter to +45°C in summer.
Underground operations in deep coal mines involve persistent threats of gas (methane) outbursts and highly explosive coal dust concentrations. Electric motors driving continuous miners, coal shearers, and heavy-duty armered face conveyors (AFCs) must be built with flameproof (Ex d / Ex de) enclosures capable of containing internal explosions. Furthermore, high starting torque and continuous thermal overload margins are essential to withstand the mechanical shocks caused by stalled shearer drums or fully loaded belt conveyors starting under load.
For open-pit operations in regions like Ekibastuz, equipment faces massive dust storms, high wind speeds, and extreme temperatures. Outdoor equipment like conveyor belts, stacker-reclaimers, and ventilation systems rely on low-voltage and high-voltage motors designed with IP66 dust-proof configurations, specialized bearing lubricants formulated for sub-zero performance, and integrated space heaters to prevent moisture condensation during shut-down phases.
Engineering electric drives that guarantee safety, efficiency, and compliance.
Fully certified and tested explosion-proof motors meeting CU-TR 012/2011 standards, guaranteeing smooth customs clearance and immediate operational legality within Kazakhstan, Russia, and Belarus.
Providing motors designed to match international energy standards IE3, IE4, and cutting-edge IE5 Permanent Magnet Synchronous Motors (PMSM) to optimize operation costs and reduce grid load.
Covering low, medium, and high voltage applications ranging from fraction-horsepower auxiliary drives to multi-megawatt heavy-duty blast furnace blower motors and coal shearers.
Unifying a century of motor engineering heritage to serve modern Kazakhstani industry.
Wolong Group’s growth has been defined by strategic acquisitions of the world’s most trusted industrial motor legacy brands. This consolidation integrates unparalleled engineering patents, design software, and materials science expertise into a unified global product line:
Acquired in 2011, Austria's ATB Group brings over a century of European industrial design excellence. Under its umbrella, Morley Motors has a 130-year legacy dedicated to underground coal mining. Morley is globally synonymous with high-torque, water-cooled, and air-cooled flameproof motors designed specifically for underground shearers and high-spec conveyor belts. Along with Laurence Scott’s low-starting-current motor technology, these designs are critical for operations connected to weak electrical grids.
Founded in Germany in 1882, Schorch has set the global benchmark for high-voltage, explosion-proof motors used in oil & gas, chemical processing, and pipeline compression. Likewise, Brook Crompton Motors provides a complete range of low-voltage and medium-voltage AC motors. Their motor designs focus on efficiency, reliability, and robust variable-frequency operation in high-duty cycle configurations.
Dating back to the strategic integration in 1999, OLI has held a leading global market share in high-efficiency concrete and material vibration systems. These heavy-duty vibration motors and Ex-certified vibration sensors are essential for ensuring smooth material flow through bins, hoppers, and screening decks in mineral processing mills throughout Kazakhstan.
In 2018, GE’s commercial and industrial motor division joined the Wolong Group. This integration introduced GE’s robust oil and gas, petrochemical, and large-scale mining engineering standards into our product line. It expanded our high-voltage motor portfolio to deliver reliable power under continuous operational stress.
Premium components designed for low maintenance, long service life, and optimal heat dissipation.
Utilizing high-mica tape insulated with polyester film and reinforced with glass cloth. Following the VPI (Vacuum Pressure Impregnation) process, the stator coils form a rigid, moisture-proof, and chemically inert block. This ensures exceptional dielectric strength, thermal dissipation, and resistance to high-frequency transients typical in VFD drives.
Cast aluminum rotors are manufactured using centrifugal casting or advanced high-pressure die-casting, creating a solid end-ring and bar assembly for reliable torque transmission. For high-power HV motors, copper-bar rotors with premium alloy bars are tig-welded to end-rings, featuring retention rings to handle high rotational inertia.
Engineered using multi-physics structural and fluid simulation platforms, our frames use high-tensile cast iron or fabricated structural steel. The design provides structural rigidity, high thermal dissipation area, and vibration dampening to ensure low mechanical wear and smooth shaft alignment.
Features an optimized aerodynamic shroud, internal sound-absorbing acoustic linings, and an IP22 protective screen. The design maintains clean airflow across the cooling ribs while reducing aerodynamic noise, complying with stringent OSHA and EU occupational noise limits.
Connecting state-of-the-art Chinese manufacturing directly to Kazakhstan's industrial centers.
Operating as a key partner of the Wolong Group, Shaanxi Nanfang Motor Technology Co., Ltd. utilizes a highly optimized supply chain that connects Chinese manufacturing directly to the Kazakhstan market. Geographically positioned near the Belt and Road logistics corridor, we export equipment through major land ports including Horgos and Alashankou, ensuring reliable transit times to industrial hubs like Karaganda, Pavlodar, Aktobe, and Almaty.
Our raw material sourcing, automated manufacturing processes, and integrated component testing allow us to maintain fast production timelines even for custom-engineered high-voltage motors. By bypassing long maritime shipping routes, we provide Kazakhstani operators with dependable lead times, rapid spare parts delivery, and swift access to engineering support.
Direct connection to the China-Europe railway, cutting transit time down to 10-15 days.
Pre-cleared certification protocols ensuring rapid clearance at Eurasian Union borders.

Aligning with local environmental policies and industrial digitalization.
As Kazakhstan moves toward modernization and carbon neutrality targets, industrial operators are looking for ways to optimize energy consumption and implement predictive maintenance. Our development roadmap integrates these objectives directly into the electric drive systems:
To reduce energy consumption in high-demand continuous applications, we are expanding the integration of our TBVF Series Permanent Magnet Motors. These motors maintain high operational efficiency across a wide range of load profiles and speed variants, offering a modern alternative to traditional asynchronous motor systems.
Deep-shaft mining and large-scale material transport depend on reliable component operation. By utilizing smart vibration sensors, RTD winding temperature probes, and predictive analysis systems, operators can monitor motor performance in real time. This allows maintenance teams to identify potential bearing fatigue or insulation degradation before a failure occurs.
Applying variable-speed drive configurations to conveyor systems, ventilation fans, and slurry pumps helps prevent mechanical shocks on startup. This limits peak demand on the local electrical grid, reduces wear on gearboxes, and cuts down on overall system maintenance requirements.
