High-reliability asynchronous drive solutions designed to withstand extreme underground and surface environments in major mining fields across Pakistan.
Pakistan is exceptionally rich in natural mineral resources, hosting vast reserves of coal, copper, gold, salt, iron ore, and chromite. The modernization of the mining sector is currently spearheaded by projects such as the Thar Coalfields (Blocks II, VI, and VIII) in Sindh, the world-class copper and gold deposits at Reko Diq in Balochistan, and the extensive underground salt mines in the Salt Range of Punjab. These projects present unique mechanical challenges, calling for next-generation electric motor drive systems.
Operating conditions in these environments are extreme. Thar Coalfields, for instance, experience high ambient temperatures exceeding +50°C and contain massive concentrations of fine abrasive dust. Underground environments pose significant hazards with volatile mixtures of methane gas and airborne coal dust, necessitating strictly certified explosion-proof (Ex d / Ex de) motor systems. Traditional motors frequently face insulation failure, mechanical wear, and premature bearing breakdowns due to insufficient environmental protection. High-efficiency, certified explosion-proof induction motors, therefore, serve as critical machinery to prevent accidents and optimize continuous mining processes.
Shaanxi Nanfang Motor Technology Co., Ltd. is the authorized distributor of Wolong Electric Drive Group Co., Ltd. Founded in 1984 and listed in 2002 (SH600580), Wolong has grown to establish 3 main manufacturing bases, 39 advanced factories, and 3 global R&D centers.
With an extensive history of strategic international acquisitions, WOLONG group integrates century-old European motor engineering heritage, providing unmatched technical support through its consolidated brands:
Tailored electrical architectures designed to maximize uptime and efficiency across critical mining systems in Pakistan.
Severe friction load starting requires high-torque flameproof motors. Our YBSS, YBSD, and YBS motor series deliver high torque, low starting currents, and are certified under global standards (ATEX/IECEx/Nemko) to handle heavy start-stops on long-distance belt conveyors.
Unmatched mechanical shock load tolerance. The YBC series coal shearer motors are engineered using highly durable copper-bar rotor configurations and class-H vacuum pressure impregnated insulation, ensuring continuous, spark-free mining output.
Continuous ventilation is critical for underground safety. YBRB pump motors and YBF fan motors deliver dependable IP65/IP66 performance, ensuring continuous extraction of hazardous mine gas and water accumulation.
A detailed breakdown of the high-grade metallurgy and insulation systems designed for maximum duty cycles.
Our rotors utilize squirrel cage dynamics, incorporating centrifugally cast pure aluminum or specialized copper bars based on performance requirements. Copper bar rotors are processed via rigorous induction welding on the end-rings to ensure high mechanical integrity under extreme centrifugal stress and reverse rotation torque spikes.
Using premium polyester-imide enameled copper wire insulated with high-grade mica tapes, our stators undergo full Vacuum Pressure Impregnation (VPI). This treatment produces a void-free structure with Class H temperature limits, protecting windings against moisture, chemical corrosion, and abrasive mining dust.
Constructed using cast iron with advanced heat-dissipation rib placement, the frame design undergoes structural and fluid dynamics multi-physics modeling. This ensures excellent thermal performance and structural rigidity to handle mechanical shock loads from mining operations.
Equipped with optimized fan structures and acoustic silencing plates, the low-noise ventilation hood delivers high air throughput at low decibel levels. The IP22-protected system is designed to prevent structural dust accumulation while providing effective heat dissipation.
As Pakistan scales up its infrastructure projects through the China-Pakistan Economic Corridor (CPEC), sourcing mining equipment with high cost-to-performance efficiency is vital. Our Wolong intelligent manufacturing plants deploy Factory 4.0 automation systems, ensuring precision assembly and standardized quality checks across production lines.
