Shaanxi Nanfang Motor Technology Co., Ltd. stands as the premium authorized distributor of Wolong (Wolong Electric Drive Group Co., Ltd., SH600580). Established in 1984, Wolong has expanded into a global powerhouse containing 3 major manufacturing bases, 39 specialized industrial factories, and 3 high-tech R&D centers worldwide.
By focusing relentlessly on motor R&D, drive control technology, and international safety compliance, Wolong delivers highly customized, robust foot-mounted induction motors (IM) designed to operate under hazardous, heavy-duty industrial parameters. With global distribution nodes, we provide unmatched local support, ensuring your operations remain up and running.
Industrial plants require more than just component procurement; they demand complete drive system solutions that reduce energy expenditure, maximize uptime, and guarantee worker safety.
In response to global decarbonization mandates, we offer IE3, IE4, and ultra-premium IE5 efficiency class foot-mounted induction motors. These machines minimize thermal losses and dramatically lower carbon footprints in continuous-duty applications.
Our VFD (Variable Frequency Drive) compatible series allow high-performance operations under dynamic torque loads. Incorporating advanced thermal monitoring, they avoid overheating at lower speeds, typical in pump and fan systems.
Fully compliant with international ATEX, IECEx, and EAC regulations, our flameproof series are specifically designed for hazardous Zone 1 and Zone 2 environments in oil refiners, offshore platforms, and coal mining fields.
Over the decades, Wolong has integrated some of the world's most prestigious and historic motor manufacturers, inheriting century-old design files, premium patents, and advanced fabrication technologies.
In 2011, WOLONG acquired 97.94% of the Austrian ATB Group, one of Europe's top three motor manufacturers. This major consolidation brought under Wolong's wings the iconic Morley brand, which carries over 130 years of history in underground coal mining equipment, and Laurence Scott, renowned for its low starting-current motors tailored for nuclear power generation and naval marine vessels.
Brook Crompton, a technological leader for over a century, has pioneered high-efficiency motor concepts. Their W-series provides exceptional reliability in severe environments. Similarly, Schorch (established 1882) joined Wolong in 2011, continuing to supply highly specialized driving systems for international oil & gas, chemical processing, and municipal wastewater infrastructures.
In 1999, Wolong forged a joint venture with OLI, the global leader in vibration motors. Later in 2015, CNE (Nanyang Explosion-proof Group), China's premier explosion-proof motor scientific base, joined Wolong. In 2018, General Electric (GE) industrial motor division was integrated, strengthening Wolong's dominance in heavy industrial mining, metallurgy, and global petrochemical applications.
Every foot-mounted induction motor is constructed using premium-grade materials and rigorous simulation platforms to withstand extreme continuous mechanical strain.
Engineered with centrifugal cast aluminum or precision die-cast pure aluminum for optimal startup torque. Larger industrial units utilize copper bar rotors with premium welding processes and protective containment rings for high-speed dynamic reliability.
Featuring polyester film reinforced with glass cloth, low-powder or medium-powder mica tapes. Every winding is treated via Vacuum Pressure Impregnation (VPI) to achieve exceptional moisture resistance, mechanical rigidity, and Class H thermal insulation.
Developed using multi-physics structural and fluid dynamic simulations. Made of high-grade cast iron or structural steel, our foot-mounting designs (e.g., B3 configuration) offer massive structural redundancy, isolating mechanical vibrations and maximizing heat dissipation.
Composed of an air guide cylinder, protective side-inlet windows, sound-dampening plates, and IP22-rated compliance. This compact structure redirects airflow to prevent recirculation and dramatically reduces structural wind-shear noise.
We export to over 58 countries by adhering strictly to global technical regulations, overcoming local trade barriers, and guaranteeing site compatibility.

To ensure optimal matching, Shaanxi Nanfang Motor evaluates the specific physical installation parameters of your site. The IM B3 (Foot Mounted) design is the foundation for mechanical coupling to high-inertia loads. Let us examine the technical parameters under specific localized applications:
| Application Environment | Primary Motor Configuration | Critical Performance Requirement | Protection & Mounting Standard |
|---|---|---|---|
| Underground Coal Mining | WOLONG YBSD/YBRB Flameproof | High starting torque, impact load resistance | IP66, Foot Mounted (B3), ATEX Zone 1 |
| Marine Auxiliaries & Pumps | YQ Low Voltage Marine Series | Salt-mist corrosion resistance, low vibration | DNV GL Type Approved, Cast Iron Frame |
| Petrochemical Refining | YZYKS High Voltage Positive Pressure | Gas leakage prevention, continuous S1 duty | Ex pxb / Ex d, CE Certification, IECEx |
| Heavy Ventilation & Fans | Brook WE Series / NEMA Standard | VFD speed regulation, low noise levels | IP55, Class F Insulation, NEMA MG1 |
As manufacturing paradigms move towards Industry 4.0, our foot-mounted induction motors are transitioning into smart nodes. By integrating high-resolution PT100 temperature sensors directly in the winding slots and bearings, and pairing them with vibration-sensing modules (such as OLI vibration sensors), we enable real-time cloud diagnostic monitoring. This allows operators to preemptively isolate bearing wear, stator insulation breakdown, or shaft misalignment, changing expensive emergency repairs into minor planned maintenance procedures.
