Explore our high-efficiency low-voltage and high-voltage motors designed for explosion-proof applications, heavy industries, and hazardous sites.
A global leader in motor drive systems, unifying world-class heritage and innovation since 1984.
Shaanxi Nanfang Motor Technology Co., Ltd. is the authorized global distributor of Wolong Electric Drive Group Co., Ltd. (founded in 1984, listed on the Shanghai Stock Exchange in 2002 under code SH600580).
Today, Wolong commands a massive global network consisting of 3 main manufacturing bases, 39 advanced factories, and 3 state-of-the-art global R&D centers. Committed to a comprehensive global brand strategy, Wolong sets the gold standard for innovation, R&D, structural design, and efficiency optimization within the global electric drive market.
Through strategic acquisitions, Wolong integrated iconic, century-old industrial brands into a singular powerhouse:
Deep-dive research on energy transitions, global regulatory compliance, and OEM procurement resilience.
In the current industrial climate, electric motors consume over 45% of global electricity. As global regulations like the European Green Deal and US DOE mandates push for net-zero carbon footprints, low-voltage induction motors must evolve.
The standard choice for modern plants is transitioning from basic efficiency ranges to premium IE3, super-premium IE4, and ultra-premium IE5 performance levels. The emergence of permanent magnet-assisted synchronous reluctance motors (PMaSynRM) represents a critical shift, enabling significant energy savings under partial load profiles typical in HVAC and pumping operations.
Our smart manufacturing hubs employ advanced automation to guarantee production consistency and structural integrity. Through the integration of automated robotic winding, precision die-casting, and digitized quality inspection tracking, China Factory 4.0 delivers unmatched structural output.
Our localized supply chain controls major raw material inputs—such as high-grade cold-rolled silicon steel and 99.99% pure copper. This vertical integration allows Shaanxi Nanfang Motor to bypass supply shocks, keeping OEM lead times stable and cost-structures optimized.
Procuring motors for global projects demands rigorous validation of engineering credentials. Standard procurement matrices require:
Deconstructing the micro-features that deliver superior performance, structural safety, and operational reliability.
Our motor coils are insulated with high-grade polyester film reinforced with premium glass cloth. We utilize low-powder or medium-powder mica tape with high mica content to achieve superior insulation properties. Following coil insertion, the stator assembly undergoes the Vacuum Pressure Impregnation (VPI) process.
This creates a dense, void-free insulation barrier that prevents moisture ingress, enhances mechanical strength, and provides Class H thermal stability for continuous operation in harsh industrial environments.
We supply squirrel cage rotors featuring centrifugally cast aluminum or high-grade die-cast aluminum configurations. Molten aluminum is cast directly into the rotor slots, forming a integrated, highly durable component with integral end rings.
For high-capacity, high-torque industrial duties, copper bar rotors are utilized. These feature custom welded copper bars with robust end-ring reinforcement. Every rotor undergoes dynamic balancing to ensure vibration levels remain far below ISO 1940 standard guidelines.
The motor frame structural design is optimized using multi-physics finite element analysis (FEA) platforms. Formulated from premium gray cast iron or structural welded steel, our frames feature optimized cooling fin geometry.
This design offers extreme structural rigidity, high resonance margins, and thermal dissipation performance that ensures low operating temperatures and extended bearing life under heavy structural stress.
The cooling air system consists of an aerodynamic fan cover, flow guide cylinder, protective mesh, and noise-damping silencer plates. The optimized side-inlet geometry minimizes airflow restrictions behind the motor, reducing energy loss and turbulence noise.
Equipped with acoustic absorbing linings, the system keeps operational noise levels exceptionally low while maintaining an IP22/IP44 touch-safe safety barrier around moving fan elements.
Unlocking access to global markets and hazardous work sites with validated safety credentials.
Our global testing operations ensure all low voltage and explosion-proof motors fully satisfy international requirements:
