Discover our elite line of European standard compliant medium and high-voltage AC electric motors configured for the Polish heavy industrial sector.
Poland represents one of the most dynamic and resilient industrial markets in Central and Eastern Europe. Driven by extensive manufacturing sectors, mineral mining complexes, and a strategic energy transition agenda, Polish enterprises require highly efficient and resilient powertrain systems. As a leading AC high voltage motor exporter, we understand the specific commercial, ecological, and technical landscapes that shape equipment procurement in this region.
Upper Silesia's coal fields and KGHM Polska Miedź's world-class copper mines present harsh, damp environments prone to explosive methane gas and dust. Explosion-proof, high-efficiency medium-voltage motors are crucial for ventilation, massive skip hoists, and continuous slurry pump operations.
Poland's thermal power infrastructure (such as Bełchatów and Kozienice) is undergoing a major transition to meet stringent EU efficiency standards. Modernizing auxiliary feed pumps, boiler draft fans, and scrubbers demands heavy-duty high-voltage induction motors with optimized start-up profiles.
With massive refining hubs operated by Orlen and Grupa Azoty, the Polish chemical sector requires safe, dependable operations. Motors serving these facilities must bear strict ATEX, IECEx, and CE certifications to ensure safe operational continuity within Zone 1 and Zone 2 environments.
In addition to heavy industry, municipal water management, waste treatment facilities along the Vistula River, and regional cement factories require continuous duty high-voltage machines. The push for decarbonization and energy savings makes switching to IE3, IE4, and IE5 efficiency classes a primary concern for procurement teams across Poland.
The high voltage motor market is undergoing a technical evolution centered on energy efficiency, structural durability, and digital process optimization.
By pairing high voltage motors (such as the Wolong YVF series) with state-of-the-art variable frequency drives, global plants are saving up to 30% of energy. This reduces mechanical stress during motor starts, protecting gearboxes and operational mechanisms from structural shocks.
Modern high voltage machines integrate smart temperature, vibration, and insulation tracking sensors. Industrial operators can assess motor health in real-time, executing predictive maintenance to mitigate costly unplanned production downtime.
Utilizing high-mica tape and high-grade polyester film, along with advanced Vacuum Pressure Impregnation (VPI), motors are capable of handling significant electrical stresses, moisture ingress, and thermal fluctuations while maintaining long operational life.
Combining local technical services with global manufacturing supremacy to bring premium motor solutions to the European continent.
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.
WOLONG successfully acquired 97.94% of the Austrian ATB Group (ATB motor), one of the three major European motor manufacturers, becoming the actual controller of ATB Group. This acquisition integrated the century-old UK mining motor brand Morley and naval power specialist Laurence Scott, drastically boosting technical R&D capabilities for hazardous applications.
Brook Crompton stands as a venerable and profoundly skilled participant within the electric motor sector, boasting over a century of mastery in motor design. Driven by technology and innovation, Brook Crompton has developed a complete range of low, medium, and high voltage AC motors, including the premium "W" and "10" series suitable for operation in hazardous and harsh environments.
Established in Germany in 1882, Schorch joined WOLONG in 2011. Schorch has set the standard for high-quality motors, providing driving systems across various heavy industries, including oil & gas, chemical engineering, water treatment, shipbuilding, and steel processing.
Dating back to the year of 1999, WOLONG started a successful joint venture with OLI, the global leader in industrial vibration motors (MVE) and Ex-proof vibration sensors, securing major global market shares.
As China's largest scientific research and production base for explosion-proof motors, Nanyang Explosion Group (CNE) joined Wolong. Their product ranges are widely integrated in nuclear power plants, military applications, deep mines, and coal-processing facilities worldwide.
Wolong acquired General Electric's commercial and industrial motor business. Combining GE's design heritage with Wolong's lean manufacturing capacity has reinforced our capability to support heavy industries globally, including materials processing, paper, cement, and petrochemicals.
Our motors are engineered using multi-physics simulation platforms and high-strength raw materials to guarantee structural integrity and long life.
The rotor features the squirrel cage design, with cast aluminum rotors being widely utilized. These rotors are produced using either centrifugal aluminum casting or die-casting techniques, where molten pure aluminum is poured into the slots of the rotor core, resulting in a single-piece construction that integrates the rotor bars and end rings. The structural integrity and manufacturing process of cast aluminum rotors guarantee the motor rotor's reliability, and also endow the motor with outstanding torque properties.
For larger capacity motors, copper bar rotors are employed, which benefit from dependable bar securing and end ring welding procedures. Additionally, the protective ring design of high-speed motors further ensures the reliable operation of the copper bar rotor.
The coil is crafted from polyester film and reinforced with glass cloth, utilizing either low-powder mica tape with a high mica content or medium-powdered mica tape with an abundance of mica. Following the VPI (Vacuum Pressure Impregnation) process, a pristine white coil emerges from the production line. After the billet is extracted from the wire, it proceeds through the VPI process to transform into a finished unit. The winding and insulation are meticulously engineered to provide exceptional electrical performance, mechanical strength, resistance to moisture, and thermal stability.
The motor frame employs a fully digital platform for structural and fluid multi-physics field simulations. This simulation platform retains the original patent's structure and design, utilizing mature, high-strength cast iron (or steel as an alternative).
The frame boasts exceptional structural redundancy, outstanding heat dissipation properties, and ample inherent frequency isolation margins for the entire machine. It is engineered to endure significant mechanical shocks, maintain a superior vibration level, and ensure a lower temperature increase in the motor.
The low-noise fan cover system comprises a fan cover body, an air guide cylinder, a protective window, and a silencer plate. Its compact structure and lightweight design facilitate vibration reduction. The air inlet is situated on the side, which optimizes the avoidance of obstacles behind the motor, minimizing adverse effects on ventilation and reducing noise caused by energy loss during propagation path changes.
The system also incorporates sound-absorbing materials that absorb noise, thereby lowering the overall motor noise. Additionally, the fan cover is rated IP22, ensuring that hands cannot come into contact with the fan.
Our electric motors are accredited with premium global certifications, removing trading barriers and ensuring seamless regional implementation.
Procuring heavy industrial motors from our Chinese manufacturing lines gives Polish and European enterprises a distinct competitive advantage.
