Understanding the environmental challenges and electric drive requirements in the world’s leading copper and lithium mining destination.
In Chile's Altiplano and the Andes mountains (e.g., Escondida, Collahuasi, and El Teniente), mining operations often take place at altitudes exceeding 3,000 meters above sea level. Standard electric motors operating in these regions face a major physical obstacle: atmospheric air density decrease.
With thinner air, the heat dissipation capability of self-ventilated (TEFC) motors drops significantly. Without appropriate engineering adaptations, a standard motor will overheat, leading to insulation failure and unscheduled downtime. To combat this, our technical team uses precise altitude derating factors and thermal modeling. We supply water-jacket-cooled motors (such as the YBBP series) or oversize the frame design with high-performance Class H insulation (run at Class B temperature rise limit) to ensure reliable continuous performance in thin air.
The Atacama Desert is characterized by extremely dry conditions, fine abrasive silica dust, and large temperature fluctuations between day and night. Silica dust can penetrate standard motor bearings and stator windings, causing rapid wear and insulation breakdowns.
Our Chilean mining-spec motors feature standard IP66 ingress protection, heavy-duty labyrinth seals (e.g., Inpro/Seal), and specialized rust-preventative epoxy coatings. These features prevent fine particulates from entering the motor, while internal anti-condensation space heaters eliminate moisture buildup during cold desert nights.
How our strategic acquisition of legendary industrial brands delivers unparalleled technical expertise to your mining operation.
Wolong acquired a 97.94% stake in the Austrian ATB Group, one of Europe's top three motor manufacturers. This acquisition integrated ATB's premium electrical designs into our global portfolio, bringing along the specialized capabilities of Laurence Scott and Morley.
With a history dating back nearly 130 years, Morley is a leading name in heavy-duty underground coal and mineral mining motors. Morley motors are engineered to survive hazardous, confined spaces and represent high-specification electrical design worldwide.
Pioneering motor supply for critical applications like British nuclear power plants and naval vessels, Laurence Scott is renowned for low-starting-current designs and high-voltage motor engineering, receiving the Queen's Award for three consecutive years.
With over a century of electric motor design expertise, Brook Crompton is a pioneer in energy-efficient motor technologies. Their portfolio includes premium "W" series low, medium, and high-voltage AC motors designed for harsh industrial applications.
Founded in 1882, Germany's Schorch sets the standard for high-power, heavy-duty industrial motors. Schorch motors are widely used in critical sectors like oil & gas, chemicals, water treatment, and large tunnel ventilation systems.
Since establishing a joint venture with OLI in 1899/1999 in China, Wolong has become a major supplier of vibration motors (MVE series) and Ex-proof vibration sensors for aggregate processing and screening plants.
Nanyang (CNE), China's largest scientific research and production base for explosion-proof motors, integrated with Wolong. This cooperation brought robust, certified ex-proof low/high-voltage motors to global mining, petroleum, and nuclear power projects.
Wolong acquired General Electric's commercial and industrial motor division. Combining GE's design expertise in medium/high voltage motors and digital drive packages with Wolong's production capacity created a comprehensive global industrial motor solution.
Engineered components designed to withstand constant vibration, voltage spikes, and dusty atmospheres.
Our rotors feature a robust squirrel-cage design. We utilize high-quality cast aluminum rotors, produced via centrifugal or die-casting techniques to form a single, integrated component with the rotor bars and end rings. For larger, heavy-duty mining motors, copper-bar rotors are employed. These use high-strength welding on the end rings and protective ring designs to prevent centrifugal distortion during high-speed VFD operation.
Our coils are insulated with high-grade polyester film, reinforced with glass cloth and high-mica-content tape. Through the Vacuum Pressure Impregnation (VPI) process, the entire stator is treated with solventless epoxy resin, creating a solid winding structure. This process provides excellent dielectric strength, resistance to moisture, and mechanical protection against copper-to-copper vibration.
Using digital multi-physics simulation platforms (fluid dynamics and structural analysis), our motor frames are constructed from high-tensile cast iron or fabricated structural steel. The design provides excellent heat dissipation, high structural rigidity to absorb external mechanical shocks, and low vibration levels to prolong bearing life.
The low-noise ventilation system consists of an engineered fan cover body, air guides, a protective mesh window, and silencer plates. The side-entry air intake minimizes blockages behind the motor and reduces noise caused by air turbulence. Integrated acoustic absorption materials help lower overall decibel levels, and the IP22 protection rating ensures safety.

Enabling green mining and digital transformation through advanced technology and high-efficiency drives.
As Chilean mining corporations work to align with global environmental goals, energy efficiency has become a critical operational requirement. Electric motors account for the majority of electricity consumed in mineral processing plants. By shifting from older IE2/IE3 motors to modern IE4 and IE5 (Super Premium Efficiency) designs, mining operators can significantly reduce carbon emissions and lower energy costs.
Our permanent magnet synchronous motor technology (such as the TBVF series) features advanced rotor magnets that eliminate rotor copper losses, providing high efficiency even under partial loads.
Unplanned downtime in a mine can cost thousands of dollars per hour. Our future technical roadmap integrates wireless IoT vibration and temperature sensors directly onto the motor frame. These sensors transmit real-time performance data to a centralized control room, allowing engineers to track temperature spikes, bearing wear, and winding insulation degradation before failures occur. This transition from reactive to predictive maintenance helps maximize plant availability.
