Engineered for high starting torque, low vibration levels, and continuous S1 duty cycles under extreme environmental parameters.
Authorized distributor of Wolong Electric Drive Group, operating a matrix of top-tier industrial electric motor brands across Europe, America, and Asia.
Shaanxi Nanfang Motor Technology Co., Ltd. serves as the premier authorized global gateway for Wolong Electric Drive Group Co., Ltd. Founded in 1984 and listed on the Shanghai Stock Exchange in 2002 (SH600580), Wolong has evolved over three decades into the absolute vanguard of industrial motor manufacturing. The group operates 3 primary manufacturing bases, 39 highly specialized factories, and 3 global R&D centers.
Through systematic, high-value cross-border acquisitions, Wolong has integrated legacy industrial motor manufacturers into a unified technology ecosystem. These include the Austrian ATB Group (incorporating Morley and Laurence Scott), Brook Crompton, Schorch, OLI, and GE Industrial Motors division. This combined industrial heritage provides unmatched capabilities in delivering CE-certified industrial air compressor motors for demanding oil & gas, petrochemical, mining, and power generation systems.
How we address the critical pain points of industrial compressed air applications—vibration control, thermal management, and explosive atmosphere safety.
Designed for Zone 1 and Zone 2 hazardous gas and dust environments. We provide complete certification compliance including ATEX, IECEx, CSA, and EAC (CU-TR) to meet stringent localized safety standards.
Meeting and exceeding international minimum energy performance standards (MEPS). We supply standard induction motors up to IE5 efficiency and ultra-efficient permanent magnet (PM) motors for Variable Frequency Drive (VFD) setups.
Access specialized engineering through Wolong's subsidiary portfolio. Rely on Schorch for heavy-duty gas compressors, Brook Crompton for modular light-industrial systems, and Nanyang ATB for explosion-proof applications.
Industrial air compressor motors require exceptional durability due to high-inertia starting and pulsating loading cycles. Here is a breakdown of our core construction details.
Designed with a cast aluminum or copper-bar squirrel cage configuration depending on frame sizes. Centrifugal casting processes eliminate air pocket voids inside the slots, guaranteeing highly uniform electrical resistivity and mechanical strength.
Stator coils utilize premium polyester-film and glass-cloth composite backings integrated with high-content mica tapes. The finished stator undergoes a Vacuum Pressure Impregnation (VPI) process to ensure a dense, moisture-proof structure.
Engineered using multi-physics structural and thermal simulations, our high-tensile cast iron frames are structurally optimized to minimize resonant frequencies and maximize convective heat dissipation.
Air compressors generate substantial sound pressure levels. Our low-noise fan cover system features integrated internal guides and sound-dampening plates, reducing the overall motor noise footprint.
Wolong's growth strategy centers on integrating century-old global manufacturing pioneers to create a unified technology portfolio.
Acquired in 2011, ATB Motor is one of Europe's three major electric motor manufacturers. Morley Motors brings a 130-year lineage of heavy coal-mining drive expertise, while Laurence Scott is renowned for low-starting-current designs and high-reliability systems utilized in British nuclear power generation and naval installations.
With over a century of technology development, Brook Crompton leads the industry in designing robust, energy-efficient motors for hazardous environments. Schorch, founded in Germany in 1882, is a benchmark for custom drives in large-scale oil, gas, and power plants, providing heavy-duty drive systems for large compressor applications.
In 2015, CNE, China's largest scientific research and manufacturing base for explosion-proof motors, joined Wolong. In 2018, General Electric (GE) Industrial Motors division joined the group, enhancing the technology stack for heavy process industries including petrochemicals, metallurgy, mining, and offshore platforms.
How Shaanxi Nanfang Motor leverages Chinese manufacturing scale and global technological shifts to offer high value for international procurement.

TESTSAFE
IECEx & ATEX Standards: Vital for exporting oil & gas or mining equipment to European markets, confirming that flameproof enclosures (Ex d, Ex de, Ex e) mitigate risks in explosive gas or dust environments.
NEMA Standards: Mechanical dimensions and electrical standards are tested to meet UL and CSA parameters for the North American market, including insulation resistance, vibration limits, and breakdown torque levels.
ISO 9001 Compliance: Ensures traceably consistent manufacturing processes from raw electrical steels to final dynamic balancing and insulation performance testing.
TestSafe Certification: Helps facilitate entry of coal mining motors and compressor systems into highly regulated markets such as Australia, providing validated safety compliance.
Our motors are configured to meet the design, ambient environment, and operating profiles of diverse industrial sites.
In facilities with flammable vapors, air compressor motors run continuously. We provide flameproof enclosures paired with thermistors and PT100 temperature sensors to monitor bearing conditions, helping to ensure safe operation in hazardous atmospheres.
Morley and Nanyang motors are built to withstand underground hazards, dust, and water spray. Featuring high structural margins and high torque curves, they provide reliable operation under varying coal and ore dust conditions.
Aeration blowers require continuous motor operation in humid, corrosive environments. We configure these motors with IP56 weatherproofing, anti-condensation heaters, and specialized paint coatings to prevent corrosion.
Answers to common technical questions from engineering managers and global procurement departments.
Rapid voltage rise times (dV/dt) from VFD pulse-width modulation can cause voltage spikes that degrade typical phase insulation. To address this, we use high-grade mica wind coatings, Class H glass-cloth insulation, and a complete Vacuum Pressure Impregnation (VPI) process to ensure void-free insulation protection.
CE conforms to European standards, typically testing under IEC 60034 parameters with metric mounting dimensions. NEMA conforms to North American specifications, specifying mechanical frame shapes and operating service factors (typically 1.15 SF). We supply both metric (IEC) and imperial (NEMA) frame designs to match varying system specifications.
Compressor systems generate high mechanical loads. High rotor vibration can lead to bearing wear and premature seal failure. Our rotors are dynamically balanced to Grade G1.0/G2.5, helping to maintain structural alignment and extend bearing life under continuous operation.
We recommend specifying an IP56 or IP65 rating, C5-M high-corrosion paint coatings, internal anti-condensation space heaters to prevent moisture buildup, and insulated bearings (such as hybrid ceramic bearings) to protect against electrical currents.
High-efficiency, low-voltage, and high-voltage motors designed for industrial blowers, pumps, and process air compressors.
