Explore our high-performance low, medium, and high voltage three-phase motors engineered for global compatibility and extreme industrial environments.
Electric motors designed in accordance with GOST standards (such as GOST 183-74, GOST 31606, and related regional specifications) represent the backbone of heavy industrial infrastructure across Eastern Europe, Russia, and Central Asia (Eurasian Economic Union - EAEU). Unlike European IEC or North American NEMA frames, GOST standard motors feature unique dimensional configurations, specific shaft alignments, core lengths, and electrical output characteristics tailored to legacy and modern regional grids operating under extreme climatic variants.
Globally, the integration of GOST-compliant machines is surging due to heavy infrastructure modernization, energy-efficiency regulations, and international investments in pipelines, extraction sites, and maritime shipping channels. Shaanxi Nanfang Motor Technology Co., Ltd, as the authorized partner of global industrial powerhouse Wolong, delivers key technologies configured precisely to these standards, bridging advanced global R&D with regional compliance parameters.

Through strategic acquisitions, Wolong integrates legendary brands such as ATB, Brook Crompton, Morley, Laurence Scott, Schorch, OLI, and the commercial/industrial motor division of General Electric (GE). This robust ecosystem guarantees top-tier performance for custom projects requiring strict EAC, ATEX, IECEx, and GOST compliance.
Delivering high-efficiency solutions and rugged motor configurations for hazardous and heavy industrial applications.
We provide a comprehensive range of explosion-proof certificates including TR CU (EAC) for the Eurasian Union, ATEX for Europe, and IECEx for global operations, covering zones 1, 2, 21, and 22.
State-of-the-art asynchronous and permanent magnet synchronous motors (PMSM) configured to reduce operating costs and support green decarbonization initiatives globally.
Spanning low, medium, and high voltage options, our portfolio satisfies demands across mining, chemical processing, oil & gas, metallurgy, and industrial automation.
With R&D centers located in Europe, China, and Japan, plus the Central Research Institute in Shanghai, we pioneer drive systems that establish international benchmarks.
Integrating global expertise from renowned legacy brands like Brook Crompton, Morley, Laurence Scott, Schorch, ATB, and GE to provide unmatched engineering depth.
Nanyang Explosion-Proof Group (CNE) provides key engineering strength, assuring highly reliable motors built to withstand critical atmospheric and mechanical shocks.
As heavy industry shifts toward digitalization, the technological roadmap for GOST standard motors is undergoing a paradigm shift. Standard three-phase asynchronous motors are transitioning into integrated smart drive systems. Our engineering focuses on three main pillars:
Tracing our path of industrial development and technical acquisitions that shaped our global capabilities.
Accumulated with abundant assets and brilliant experiences in manufacturing, Wolong reached for higher targets by acquiring prominent overseas groups to become a leading manufacturer of AC motors & drives worldwide.
In 2011, Wolong acquired 97.94% of the Austrian ATB Group (including Morley and Laurence Scott), obtaining key technology platforms. Morley, with its nearly 130-year history, is a renowned brand in underground coal mining. Laurence Scott is highly regarded for low starting current designs and specialized naval applications.
In 2011, Schorch joined Wolong, bringing a reputation established in 1882 for top-tier motors in oil & gas, chemicals, and water treatment. In 2015, China's largest explosion-proof base, Nanyang Explosion-Proof Group (CNE), joined Wolong. In 2018, General Electric's (GE) industrial motor division was integrated, strengthening Wolong's overall industrial capabilities.

GOST standard motors are engineered to operate in specific environments typical of EAEU oil and gas terminals, metallurgical mills, and chemical plants. Our customized OEM configurations meet these specific localized demands:
Exploring the internal engineering and materials that support the performance of our three-phase motors.
Featuring a squirrel cage design with cast aluminum rotors produced via centrifugal or die-casting techniques. For larger capacities, copper bar rotors with secure bar locking and end ring welding are utilized. The protective ring design on high-speed motors supports reliability and stable torque characteristics.
Coils are insulated with glass cloth reinforced polyester film and high-mica content tapes. Following the VPI (Vacuum Pressure Impregnation) process, the stator core achieves high electrical insulation resistance, mechanical strength, moisture resistance, and thermal stability.
Frames are designed using multi-physics structural and fluid simulation platforms. Cast in high-strength iron or fabricated steel, the frame provides robust heat dissipation, mechanical redundancy, and vibration damping margins.
Consists of a body cover, air guide cylinder, protective window, and silencer plate. Incorporating sound-absorbing materials and a side air inlet design, it reduces energy loss, minimizes noise, and carries an IP22 rating to prevent internal contact.
Providing custom drive configurations across various manufacturing plants and engineering projects worldwide.
Wolong maintains 39 manufacturing facilities and 4 R&D centers globally across China, Vietnam, the United Kingdom, Germany, Austria, Italy, Serbia, Mexico, and India.
Our motors serve as primary drives for fans, water pumps, compressors, and heavy engineering machinery. These solutions support key operations in refrigeration, commercial construction, oil & gas extraction, petrochemical refining, coal chemistry, metallurgy, nuclear power generation, marine transport, and automated industrial plants.
A dimensional and electrical overview comparing regional motor standard frameworks.
Addressing key queries related to standard compliance, mechanical installation, and operations.
The differences are primarily mechanical and dimensional, alongside specific documentation requirements. Although both operate on metric scales, GOST motors specify different shaft extensions, center heights, and frame mountings (e.g., IM1081 foot mounting, IM2081 flange-foot mounting) compared to IEC equivalents of the same power rating. Additionally, GOST motors must comply with TR CU certificates (EAC certification) for deployment in EAEU markets.
Our motors are constructed with low-temperature materials, high-tensile cast iron or carbon steel frames, and low-temperature grease. We install internal anticondensation space heaters inside the stator wind cavity to prevent frost buildup, assuring startup and operation at ambient temperatures as low as -60°C.
Yes. By utilizing our advanced WEPM series permanent magnet motors or YVF series variable frequency induction motors, users can deploy variable speed regulation. It is essential that the stator winding insulation utilizes VPI processing with reinforced mica tapes to withstand voltage spikes from VFD pulses.
Vacuum Pressure Impregnation (VPI) ensures that the insulating varnish penetrates the stator windings completely, eliminating air pockets. This process provides high dielectric strength, resistance to moisture and chemical agents, and improved thermal conductivity, supporting the motor's operation in harsh environments.
Yes. Modern units can be fitted with vibration sensors and temperature RTDs within the windings and bearings. When connected to digital monitoring systems, these sensors provide telemetry data that helps detect early imbalances, prevent mechanical damage, and optimize maintenance schedules.
