Explore our highly-engineered, CE-compliant replacement options for diverse global industrial settings.
Analyzing procurement expectations, regulatory compliance, and carbon footprint reduction strategies for modern industries.
Global industrial operations consume over 40% of standard grid power through electric motor systems. Upgrading older, inefficient motors to state-of-the-art IE4 and IE5 standards dramatically reduces operational expenses and keeps facilities aligned with localized net-zero parameters.
Replacing standard utility motors in heavy processing domains (such as refineries, mining operations, or chemical processing environments) requires deep adherence to strict global benchmarks: CE mark, ATEX directives, and IECEx certifications for explosive dust and gas threats.
A primary friction point in electric motor replacement is mechanical footprint configuration. Our optimized designs support precise direct fitments, ensuring matching shaft heights, bolt circles, flange configurations, and terminal box locations to replace legacy units with zero downtime.
Shaanxi Nanfang Motor Technology Co., Ltd. stands as the premier authorized distributor of the Wolong Electric Drive Group Co., Ltd. Founded in 1984 and listed on the Shanghai Stock Exchange in 2002 (code SH600580), Wolong has achieved massive international growth over the last 40 years. Today, the corporation commands 3 key manufacturing hubs, 39 individual production factories, and 3 advanced global R&D centers, positioning itself at the leading edge of electric drive manufacturing.
Through strategic acquisitions, Wolong has integrated some of the world's most historically significant industrial names into its industrial ecosystem. This includes the acquisition of the Austrian ATB Group in 2011 (incorporating mining heavyweights Morley and marine excitation specialists Laurence Scott), UK-based Brook Crompton Motors, German high-voltage manufacturer Schorch, global vibration expert OLI, and Nanyang Explosion Protection Group (CNE). In 2018, Wolong acquired the Industrial Solutions division of General Electric (GE), further elevating its engineering capability and capacity to manufacture commercial and industrial electrical units for complex heavy industries worldwide.
Targeted solutions developed for specific hazards, efficiency targets, and demanding environmental conditions.
Explosion protection is at the heart of our technical competency. Leveraging Nanyang Explosion Protection Group's technology, we design systems that safely manage threats in Zones 1, 2, 21, and 22, ensuring complete security in oil & gas, mining, and petrochemical setups.
Providing custom asynchronous induction layouts along with advanced variable frequency speed Regulation PM motors (WEPM/TBVF series). Offering efficiencies up to IE4 and IE5 classifications, which significantly reduces energy losses during high-capacity variable speed processes.
We manage replacement profiles ranging from low-voltage workhorse units to high-voltage, non-sparking, positive-pressure induction installations. No matter how challenging the setting, our replacement solutions fit without structural modifications.
By bringing historic entities like Brook Crompton, Schorch, Laurence Scott, and ATB under the Wolong umbrella, we've established a global knowledge center. The team combines Laurence Scott’s expertise in low starting currents with Schorch’s deep understanding of critical marine and refinery processes, offering customers high-quality electrical engineering solutions across international borders.
Additionally, with our joint developments alongside OLI in vibration motor manufacturing and GE in heavy-duty commercial motor drives, we deliver exceptional reliability to users managing bulk material sorting, mineral extraction, and steel processing.
A closer look at the key component structures designed for extended service life in demanding industrial applications.
Our rotors feature robust squirrel cage geometries, utilizing premium cast-aluminum cores for smaller applications, produced via centrifugal casting or high-pressure die-casting. This single-piece construction integrates both bars and end rings, delivering high mechanical strength and stable torque output.
For high-capacity, high-torque systems, we use heavy-duty copper bars with reliable mechanical bracing and welded end-ring designs. High-speed rotors also feature custom alloy retaining rings, ensuring dynamic stability and preventing conductor deformation under high rotational stress.
The stator windings are wound using high-grade polyester-imid or polyamide-imid enameled wires, insulated with premium-grade glass-backed mica tapes. The assembled core then undergoes a comprehensive Vacuum Pressure Impregnation (VPI) cycle using solventless epoxy resins.
This process eliminates microscopic air pockets in the slots, creating a solid, moisture-resistant block with excellent dielectric strength and thermal dissipation properties. The insulation system is rated Class F or Class H, providing an ample safety margin against temperature spikes.
Developed using comprehensive multi-physics structural and thermal flow simulations, our motor frames are constructed from high-tensile cast iron or fabricated steel plates. This ensures maximum rigidity, high resonance isolation, and structural stability against pipe-end loads and external shocks.
The external cooling fins are optimized for efficient airflow, helping to maintain uniform temperature distribution and reduce thermal gradients that can shorten bearing life.
Our low-noise cooling systems include aerodynamically optimized fan shrouds, directional guide cylinders, and specialized acoustic dampeners. Designed for bidirectional operation, the fan geometry reduces air turbulence and energy losses, keeping noise levels well within strict workplace standards.
With an IP22/IP55 rated protective mesh, the intake system prevents foreign particles from entering, ensuring consistent cooling performance in dusty environments.
Facilitating seamless deployment across regions with fully certified and compliant designs.
To support global trade and simplify project integration, WOLONG motors hold approvals from leading international safety and certification bodies. From standard low-voltage applications to specialized hazardous location equipment, our motors are built to meet the requirements of your operating region.
