Optimized heavy-duty AC electric drive systems built to withstand hazardous conditions in Eastern Europe. Standardized under IEC/ATEX protocols.
Romania represents one of the fastest-growing industrial corridors in South-Eastern Europe. The consolidation of heavy manufacturing, petrochemical refining (e.g., in the Ploiești, Constanța, and Midia regions), and regional water treatment infrastructure demands robust electrical drivetrains. Romania's commitment to modernization requires upgrading legacy medium and high voltage electrical machinery to meet the EU's strict safety and decarbonization mandates.
Whether powering high-volume pipeline compressors in gas corridors, driving massive slag pumps in metallurgy plants like Galați, or operating high-pressure fans in regional power stations, high voltage (HV) AC induction motors serve as the operational backbone of these enterprises. As Romanian industries transition to energy-efficient platforms, selecting the right partner for ATEX-certified, IEC-compliant, and high-reliability HV motors becomes essential for long-term growth.
Analyzing the global high-voltage motor market and the rising demands for low carbon emissions, digital twins, and harsh environment endurance.
Global climate goals and strict EU regulations demand motors with lower energy losses. We supply high-voltage induction motors and permanent magnet systems that lower operating costs and reduce carbon footprints.
Modern petrochemical and oil-gas refineries require strict safety standards. The motor lines feature ATEX, IECEx, and EAC certifications, allowing them to operate safely in Zone 1 and Zone 2 hazardous gas and dust environments.
By using temperature, vibration, and acoustic sensors, modern heavy duty systems enable real-time health monitoring. This prevents unexpected downtime and supports predictive maintenance programs.
Shaanxi Nanfang Motor Technology Co., Ltd is the authorized global 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 rapid expansion, Wolong operates 3 manufacturing bases, 39 advanced factories, and 3 R&D centers globally. Wolong remains dedicated to manufacturing top-tier electric motors and control systems, establishing itself as a global leader in motor design, performance, and international supply chains.
Through strategic acquisitions, Wolong has integrated several renowned global industrial motor brands. This allows us to supply Romanian industries with solutions backed by generations of European engineering excellence.
By bringing together elite motor brands under one parent company, Shaanxi Nanfang provides specialized technical support and direct factory pricing for the following historical powerhouses:
Designed for reliable operation, low vibration levels, and efficient thermal dissipation in heavy industrial environments.
Our rotors feature high-grade squirrel-cage designs. For smaller and medium capacities, centrifugal cast aluminum or die-cast aluminum is used, casting the rotor bars and end rings into a single, durable piece. This design provides high structural strength and reliable starting torque.
For larger high-voltage applications, we use hand-inserted copper bar rotors. The copper bars are securely fitted into the slots and joined to the end rings using high-frequency induction brazing. High-speed models also include high-strength non-magnetic retaining rings to keep the rotor stable under high centrifugal force.
The stator windings are insulated using high-grade polyester film, glass cloth, and high-purity mica tape. After winding, the entire stator core goes through the Vacuum Pressure Impregnation (VPI) process with Class H solventless resin, followed by oven curing.
The VPI process removes air voids and moisture from the insulation system. This results in a solid winding block with high electrical resistance, structural stability, excellent heat transfer, and long-lasting protection against moisture and chemical corrosion.
The motor frames are designed using advanced structural and fluid multi-physics simulations to optimize mechanical strength and heat dissipation. Built from high-grade cast iron or fabricated steel plates, the frames offer high structural stiffness and low vibration levels.
The external cooling fins or internal heat exchange tubes are designed to prevent resonant vibrations and handle mechanical shock. The frame includes ground connections, lifting lugs, and separate IP55/IP66 terminal boxes for high-voltage power cables and internal monitoring sensors.
Our motors feature optimized cooling layouts to match different operating conditions. IC411 models use external cooling fans under high-efficiency fan hoods, while IC611 (air-air heat exchangers) and IC81W (air-water heat exchangers) designs are used for more demanding setups.
The low-noise fan hood system includes a lightweight cover, air guides, protective grilles, and sound-absorbing acoustic panels. These panels direct airflow over the frame while reducing windage noise, ensuring compliance with local workplace safety laws.
Our high-voltage AC motors comply with strict international standards, ensuring safe installation in hazardous zones and high-demand applications worldwide.
We work closely with major international testing bodies to certify our motors for chemical, petrochemical, oil, gas, and coal mining applications:
