As the authorized distributor of Wolong and Wolong Electric Drive Group Co., Ltd. (founded in 1984 and listed in 2002, SH600580), we serve as a major conduit for global supply chains seeking optimal industrial drive economies. Wolong operates 3 R&D centers, 39 manufacturing factories, and 3 high-volume production bases worldwide.
Wolong has systematically integrated premier legacy brands into a unified industrial drive powerhouse. By consolidating technological methodologies from century-old brands—such as Brook Crompton, Laurence Scott, Schorch, Morley, and General Electric's commercial/industrial unit—Wolong guarantees unparalleled technological scale, ensuring optimized initial CAPEX and minimal operational OPEX for large-scale engineering projects globally.
A comprehensive breakdown of variable costs, efficiency grade impacts, and certification premium valuations for institutional procurement officers.
The manufacturing cost of high-voltage and low-voltage electric motors is heavily determined by copper stator windings (comprising roughly 20-30% of standard motor material costs) and cold-rolled silicon electrical steel sheets (35-40%). Scale procurement and optimized supply chains mitigate volatility, passing material savings directly to end-users.
Upgrading from IE3 (Premium Efficiency) to IE4 (Super Premium) and IE5 (Ultra-Premium, Permanent Magnet PMSM) increases initial capital expenditure. However, with motor energy use accounting for over 90% of lifecycle costs, purchasing highly efficient motors yields dramatic return-on-investment (ROI) by slashing operating expenditures.
Explosion-proof motors (such as ATEX, IECEx, and CSA certified lines like YBX5 or WEBP3) command cost premiums due to thicker flameproof enclosures, labyrinth seals, and exhaustive safety validation. Wolong’s in-house testing minimizes third-party processing lead times and associated margin markups.
Engineering projects within the oil, gas, chemical, mining, power generation, and marine sectors require customized drive solutions that operate safely in extreme environments. Shaanxi Nanfang Motor Technology delivers specialized configurations developed by Wolong's global R&D network:
Certified drive platforms that safely contain internal explosions or prevent electric spark propagation, specifically engineered for combustible gas (Zone 1/Zone 2) and dust hazardous locations.
Advanced variable-frequency permanent magnet motors (WEPM series) designed to dramatically lower grid load and operational utility costs in industrial ventilation, municipal pumping, and raw material conveyance.
Vast portfolio of motor housings tailored for tough environments, featuring high-strength cast-iron shells, custom fan ventilation setups, and water-cooled systems (YBBP series).
Institutional procurement is shifting focus from initial purchase price (CAPEX) to lifecycle economics (TCO) and compliance verification. Our electric motor solutions offer several distinct strategic benefits:
Wolong's growth is driven by the strategic integration of the world's most trusted motor manufacturers. This collective legacy of engineering expertise guarantees high reliability and keeps production costs highly competitive.
Acquired in 2011 (97.94% holding), ATB is one of Europe's top three motor manufacturers. This acquisition integrated the famous Morley mining drive brand (boasting over 130 years of underground mining engineering heritage) and Laurence Scott (historic manufacturers of specialized low-starting-current marine and nuclear utility drives).
As a global leader in high-efficiency design with a century of experience, Brook Crompton joined the Wolong Group to expand its premium line of low-voltage and medium-voltage AC motors. This includes the highly robust Brook Crompton "W" and "10" series, engineered specifically for aggressive chemical environments.
Founded in 1882 and acquired in 2011, Schorch sets the standard for high-power drive installations in petrochemical, metallurgical, and heavy industrial facilities. Additionally, the partnership with OLI provides industry-leading technology in industrial vibration motors and explosion-proof vibration sensors.
In 2015, CNE—China's largest research and production base for explosion-proof motors—officially merged with Wolong to secure high-performance manufacturing advantages for oil, coal, and nuclear power utilities. This was further strengthened in 2018 when General Electric (GE)'s commercial and industrial motor division integrated into Wolong. This partnership provides robust technological support and extensive engineering expertise to global heavy industry clients.
A close look at the design choices and manufacturing quality that define our electric motors.
Features a robust squirrel-cage design using centrifugal cast-aluminum and premium die-cast options to integrate the rotor bars and end rings into a single piece. For larger high-voltage applications, copper bar rotors with high-spec bar-securing and end-ring welding are used, alongside protective rings to ensure safe operation at high speeds.
Coils are insulated with polyester film, glass cloth, and high-mica content tape, then treated with the Vacuum Pressure Impregnation (VPI) process. This advanced engineering delivers exceptional dielectric strength, mechanical toughness, moisture resistance, and thermal stability in extreme ambient temperatures.
Designed using structural and fluid multi-physics simulations, the high-strength cast-iron or steel frame boasts excellent heat dissipation and natural frequency isolation margins. It is engineered to absorb mechanical shocks, minimize vibration, and keep operating temperatures low.
This lightweight system includes a fan cover, air guide cylinder, protective window, and silencer plate. A side-entry air inlet helps bypass obstacles behind the motor, reducing turbulent noise. The design features sound-absorbing materials and is rated IP22, keeping fingers and tools safely away from moving parts.
To ensure smooth international trade and meet strict local safety rules, Wolong motors comply with all major global industry standards. Our products have passed testing by leading certification bodies:
ISO 9001 Ex Standard: Wolong maintains certified facilities under the ISO 9001 framework, establishing a solid foundation for top-tier quality management, consistent raw material testing, and reliable product tracking.
NEMA Standard (North American Markets): To ensure electrical and mechanical compatibility, our motors undergo strict efficiency tests, insulation resistance checks, starting current evaluations, and noise/vibration testing. We also carry UL and CSA certifications for our low-voltage lines.
IECEx & ATEX Standards (European & International Hazardous Zones): Essential for safety in potentially explosive atmospheres, our high-voltage and low-voltage flameproof designs are fully certified to ATEX and IECEx standards for safe operation in Zone 1 and Zone 2 areas.
TESTSAFE (Australian Coal Mining): The acquisition of Testsafe certification has opened the door for our mining motors to enter Australia and other major global markets, demonstrating the exceptional durability of Wolong coal mining equipment in tough conditions.
As global industries move toward carbon neutrality, we are adapting our technology to meet new eco-friendly goals, reduce energy losses, and implement predictive maintenance systems.
By integrating wireless vibration, temperature, and current sensors directly into the motor housing, we enable continuous status monitoring. This allows maintenance teams to spot potential issues early, preventing costly downtime and optimizing operating expenses.
We are expanding production of our premium WEPM series permanent magnet motors. These drives offer excellent torque even at lower speeds and achieve efficiency ratings beyond the new IE5 standard, saving energy across a wide range of industrial applications.
By streamlining our production lines, sourcing recycled electrical steel, and transitioning to eco-friendly varnishes, we are significantly lowering the carbon footprint of each motor before it even reaches your facility.
Key insights on pricing variables, lead times, custom configurations, and certification requirements.
Pricing is mainly driven by copper winding volume, the grade of silicon steel laminations used, frame size, and target efficiency levels (IE3 vs IE4 vs IE5). Additional factors include protective coatings, specialized bearings, and custom explosion-proof certifications (such as ATEX or IECEx) which require more robust enclosures and strict quality testing.
While high-efficiency motors like the WE3 or WEPM series have a higher upfront cost, they significantly lower energy use. Since energy consumption makes up over 90% of a motor's lifetime costs, upgrading to IE4 or IE5 can pay for itself within 12 to 24 months of heavy operation.
Yes, we offer extensive customization. This includes custom shaft dimensions, specialized bearing options (such as insulated bearings for VFD use), unique terminal box placements, mounting configurations, integrated heaters, and custom RTDs for real-time temperature tracking.
Our explosion-proof motors are certified by leading global bodies to meet ATEX, IECEx, CSA, and SABS standards. This means they are constructed with robust flameproof housings and tight seals designed to safely contain internal sparks and withstand harsh operating conditions.
