Explore our premium grade products built on cutting-edge electromagnetic designs, high performance rotors, and certified mechanical configurations.
In the modern industrial landscape, electric motors consume over 45% of global electrical energy. Low voltage AC motors serve as the workhorses of manufacturing, municipal water facilities, petroleum mining, and ventilation systems. As carbon neutrality targets tighten worldwide, procurement teams must look past nominal prices. Choosing an elite Low Voltage AC Motor manufacturer requires balancing high efficiency, structural robustness under explosive environments, international standard alignments, and reliable global distribution.
We provide comprehensive solutions meeting IE3, IE4, and advanced IE5 standards. Premium steel laminations and dynamic slot packing configurations keep losses to an absolute minimum.
Certified by ATEX, IECEx, EAC, and TESTSAFE. Our flameproof (Ex d) and increased safety (Ex e) low voltage designs guarantee safe operations in extreme mine, gas, and oil settings.
Incorporating international acquisitions like GE, ATB, Brook Crompton, and Schorch to provide a global product portfolio compliant with both NEMA and IEC standards.
Shaanxi Nanfang Motor Technology Co., Ltd is the authorized distributor of Wolong Electric Drive Group Co., Ltd. Founded in 1984 and listed on the Shanghai Stock Exchange in 2002 (code SH600580), Wolong has expanded its footprint through three decades of dynamic industrial development.
Through rigorous technology research and aggressive strategic acquisitions, Wolong has unified several century-old motor brands under its industrial portfolio. Our combined production scale, design database, and testing capabilities enable us to resolve complex mechanical challenges and deliver standard and specialized low voltage AC motor units to clients across 58 countries.
ATB, Morley & Laurence Scott: In 2011, Wolong acquired the Austrian ATB Group, including Morley (founded 130 years ago, synonymous with underground coal mine motors) and Laurence Scott (famed for low starting currents, nuclear applications, and naval vessels). This combined engineering wisdom guides our high-durability low-voltage mine conveyor and blower solutions.
Brook Crompton & Schorch: Brook Crompton stands as a pioneer in energy-efficient motors (featuring the legendary "W" and "10" series). Schorch, established in Germany in 1882, provides custom drive systems for heavy petrochemical and shipbuilding fields. These systems ensure stable operation under severe low-voltage grid fluctuations.
CNE Nanyang Explosion-proof Group: Joining Wolong in 2015, CNE is China's largest scientific research and production center for explosion-proof motors. By bringing CNE into the fold, we gained market-leading manufacturing advantages in low and high voltage flameproof asynchronous motors.
General Electric (GE) Partnership: In 2018, GE's commercial and industrial motor division became part of the Wolong Group. This integration brought advanced NEMA testing practices, premium insulating materials, and high-efficiency low-voltage industrial designs into our global production ecosystem.
Our low voltage AC motors are engineered for long service life, minimum noise emission, and high reliability under heavy mechanical stresses.
The rotor features a squirrel cage design utilizing cast aluminum, produced through high-pressure centrifugal casting or precision die-casting. This forms a single-piece structure that integrates the rotor bars and end rings, ensuring high structural integrity and excellent starting torque characteristics.
For heavy-duty applications, copper bar rotors with premium welding techniques are used, preventing bar rupture during rapid starts or reversing cycles. High-speed options feature a protective ring design to control centrifugal force deformation.
We craft our coils using polyester film reinforced with glass cloth, wrapped in medium or high-content powdered mica tape. The stator assembly undergoes the Vacuum Pressure Impregnation (VPI) process to eliminate microscopic air pockets and moisture.
This rigorous insulation scheme provides excellent electrical integrity, mechanical stability, and thermal resilience (Class F/H rating), allowing the motor to withstand high VFD-induced voltage spikes.
Our cast iron and steel motor frames are developed using digital platforms for structural and fluid multi-physics simulations. These designs provide ample structural margins, high natural frequencies, and excellent thermal dissipation.
This rigid frame structure helps isolate internal vibration harmonics, maintains bearing alignment, and protects critical motor components from external mechanical shocks.
Our low-noise fan cover system integrates a compact fan cover body, air guide cylinder, protective window, and silencer plates. The side air inlets reduce noise generated by changes in airflow direction.
Combined with internal sound-absorbing materials, the system keeps noise levels low. Rated at IP22, the fan cover prevents accidental contact with the rotating fan blades.
Unifying manufacturing scale, raw material vertical integration, and deep compliance testing to deliver global industrial products.
Our domestic Chinese supply network provides direct access to high-grade silicon steel sheet rolls, high-purity electrolytic copper, and casting facilities. This vertical integration keeps quality high and lead times short.
Our facilities employ robotic winding lines, CNC machining, and automated varnish dipping systems. By minimizing manual production variations, we achieve tight geometric tolerances and long motor life.
We leverage efficient engineering structures and advanced supply chain management to deliver premium IE3 and IE4 low voltage AC motor packages at competitive price points.
To support global supply chains, our low voltage and explosion-proof AC motors are certified to cross international borders easily.

Our high-efficiency YE3 and YE4 series motors run continuously in large municipal pumping stations, wastewater treatment plants, power generation cooling loops, and high-volume ventilation systems.
Find answers to common questions about selection, compliance, and custom engineering for low voltage AC motors.
Low voltage AC motors typically operate at voltages below 1000V (e.g., 220V, 380V, 400V, 460V, or 690V). They are widely used in commercial and general industrial applications due to their simplified safety requirements, lower installation costs, and ease of maintenance. High voltage motors operate above 1000V and are typically reserved for large-scale pumps, compressors, or mill systems that require high power outputs.
The Vacuum Pressure Impregnation (VPI) process places the dry wound stator under a vacuum to extract air pockets, then injects resin under high pressure. This results in a void-free structure with excellent moisture resistance, high mechanical strength, and good heat dissipation, which protects the stator windings from premature failure under harsh operating conditions.
IE4 (super premium) and IE5 (ultra-premium) motors feature optimized rotor laminations and stator winding layouts that reduce internal energy losses. Over the motor's operating life, the reduction in electricity consumption can offset the higher initial purchase price, especially in continuous-duty applications like municipal pumps and cooling fans.
Yes. Our YBBP and YVF series variable frequency three-phase asynchronous motors are designed to operate with VFDs. They feature reinforced winding insulation to handle high voltage spikes and, when required, auxiliary cooling fans to maintain proper motor temperature at lower operating speeds.
