Explore our elite range of explosion-proof conveyor and mining cutter motors designed for operational stability under extreme tropical conditions.
The Central African Republic is highly recognized for its extensive reserves of diamonds, gold, uranium, copper, and iron ore. Developing these resources requires heavy excavation machinery operating continuously under harsh sub-Saharan environmental conditions.
Mining operations in key areas like Lobaye, Mambéré-Kadéï, and Bria demand equipment that can withstand high relative humidity, intense rain seasons, and severe dust infiltration. In addition, the domestic electricity grid remains developing, meaning local operators face frequent voltage dips, power surges, and phase imbalances.
To prevent costly downtime, mining companies require heavy-duty electric motors equipped with high IP ratings (IP56/IP66), premium winding insulation (Class H), and dynamic starting capabilities that accommodate erratic local generator feeds. Our customized industrial motors address these localized challenges with unparalleled mechanical resilience.
Your Premier Global Distributor of Wolong Electric Drive Solutions
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). After more than 30 years of development, Wolong has 3 manufacturing bases, 39 factories, and 3 R&D centers worldwide now.
Wolong has always focused on the manufacture of motors and control systems, committed to a global brand strategy, making Wolong a leader in R&D, technology, process, manufacturing, and sales in the global market.
Through acquisitions of century-old industrial motor brands like ATB, Brook Crompton, Morley, Laurence Scott, Schorch, OLI, and GE Industrial Motors, we offer the most extensive technical expertise in high-voltage, low-voltage, and certified explosion-proof drive platforms globally.
Exceeding international standards for dangerous and high-stress industrial operations
We provide a comprehensive range of explosion-proof certificates (Ex d, Ex de, Ex e, Ex nA) tailored specifically for hazardous gas and dust environments in your specific industry and market.
IE3, IE4, and ultra-premium IE5 efficiency options are available, alongside advanced permanent magnet motor systems that significantly lower electricity overhead in remote off-grid operations.
A massive global production matrix covering high-voltage, low-voltage, variable speed regulation drives, and vibration-proof motors designed to operate reliably in hazardous mine structures.
Combining over a century of European design with world-scale manufacturing capabilities
WOLONG successfully acquired 97.94% of the ATB Group, one of the three major European motor manufacturers. This brought Morley and Laurence Scott into the family. Morley has over 130 years of history in underground coal mining equipment, manufacturing high-performance, high-specification electrical equipment. Laurence Scott pioneers low starting current designs, supplying motors for British naval vessels and nuclear plants.
Founded in 1882, Schorch sets the standard for high-power drive systems across oil and gas, shipbuilding, and chemical fields. Brook Crompton contributes over a century of electric motor expertise. Together, they helped establish a complete range of low, medium, and high-voltage AC systems including the premium Brook Crompton 'W' and '10' series.
China's largest explosion-proof motor research and manufacturing base officially merged with WOLONG. This integration consolidated our leadership in explosion-proof technology for oil and gas, mining, chemical processing, and nuclear power utilities.
The industrial and commercial motor division of General Electric (GE) joined WOLONG. With its extensive experience in manufacturing robust, high-performance machines for heavy industries, GE provided a huge technology expansion to our global production matrix.
An inside look at our robust design engineering built for hazardous conditions
The rotor features a rugged squirrel cage design. Cast aluminum rotors are produced using centrifugal casting or die-casting techniques, creating a solid single-piece construction integrating rotor bars and end rings. This guarantees outstanding torque properties.
For larger capacities, copper bar rotors with reliable end-ring welding are employed. High-speed models include an additional protective ring design to ensure high rotational reliability under variable loads.
The stator coil is constructed from advanced polyester film reinforced with glass cloth and high-mica-content tape. Following a rigorous Vacuum Pressure Impregnation (VPI) process, a moisture-proof, chemically resistant, and thermally stable stator system is delivered.
This design secures high dielectric strength, structural integrity, and long service life under thermal stress, meeting Class H or F standards.
Our frames utilize digital simulation platforms (structural and fluid multi-physics fields) to optimize strength. Using premium cast iron or structural steel, they feature high structural redundancy, excellent heat dissipation, and natural frequency isolation.
This ensures the motor survives severe mechanical shocks and operates with minimum vibration levels in mining installations.
Comprising a fan cover body, air guide cylinder, protective window, and silencer plate, this system utilizes sound-absorbing materials to lower high-frequency airflow noise.
The system features an IP22 rating, preventing structural contact with moving parts and protecting maintenance staff working in close proximity.

ISO 9001 standard: Represents our core foundation for quality control, managing development and testing consistency across all global factories.
NEMA standard: We conduct thorough testing including insulation resistance, starting current, torque limit curves, and vibration tests. We have successfully acquired UL and CSA certifications for our low-voltage motors.
IECEx & ATEX: For hazardous locations, our high and low-voltage motors are fully certified, facilitating import and installation across Europe and Africa.
TESTSAFE: This certification has established the foundation for our coal mining motors to enter the Australian and oceanic mining regions, highlighting the adaptability of our machinery in global markets.
Adapting to the future of smart, sustainable, and high-efficiency operations
With local CAR electricity supplied primarily through isolated generator hubs or limited lines, we offer customized synchronous brushless excitation motors (TAW series). These provide power factor correction and stability under grid fluctuations.
Our collaboration with OLI and integration of Ex-proof vibration sensors allows mining operators in remote CAR locations to run predictive maintenance protocols. This helps prevent sudden machinery failure before it happens.
Transitioning from standard induction to permanent magnet (PM) synchronous systems (TBVF and WEPM series) can reduce energy consumption by up to 15%. This matches global carbon reduction trends and reduces reliance on expensive imported diesel.
A comprehensive selection of explosion-proof variable frequency, permanent magnet, and high-voltage motors for pumping and heavy ventilation.
Navigating logistics and import regulations in the Central African Republic requires experienced coordinators. Since CAR is landlocked, heavy machinery shipments are typically routed through Cameroon's Port of Douala before traveling via the overland transit corridor to Bangui and final mine sites in Yaloké, Bria, or Lobaye.
We work with international logistics providers to ensure our motors are packed in robust, seaworthy structural timber crates. These are protected against tropical humidity using desiccants and heavy vacuum barrier foils.
We provide comprehensive import documentation including Certificate of Conformity (CoC), ATEX/IECEx compliance certificates, and detailed installation schematics. This facilitates smooth customs clearance and rapid on-site commissioning by field engineering teams.
