Explore high-voltage, low-voltage, explosion-proof, and variable frequency three-phase AC asynchronous induction motors engineered for demanding industrial environments.
Shaanxi Nanfang Motor Technology Co., Ltd. is the authorized global distributor of Wolong. Wolong Electric Drive Group Co., Ltd. was founded in 1984 and successfully listed on the Shanghai Stock Exchange in 2002 (Stock Code: SH600580). Over the past three decades of targeted development, Wolong has expanded to encompass 3 main manufacturing bases, 39 advanced factories, and 3 premier R&D centers globally.
Wolong's core mission centers on the manufacture of electric motors and control systems, driven by a global brand strategy that positions it at the absolute forefront of R&D, manufacturing technology, safety certification compliance, and global sales distribution.
In 2011, WOLONG company acquired strong technical support by acquiring 97.94% of the Austrian ATB Group (ATB motor), becoming the controller of ATB Group, which includes:
In modern industrial applications, procuring 3-phase motors involves navigating strict environmental regulations, efficiency mandates, and supply chain complexities.
Over 95% of a motor's lifetime cost comes from electricity consumption. Upgrading from IE3 to IE4/IE5 ultra-high efficiency designs provides a rapid ROI, directly aligning with industrial decarbonization initiatives globally.
Leveraging our global footprint, including 39 factories and local warehousing partners across Europe, North America, and Australia, we significantly reduce shipping lead times and mitigate global logistics volatility.
Different jurisdictions enforce localized grid and safety codes. Our team offers a single, global point of contact for unified engineering designs meeting ATEX (Europe), Class/Division (US), SABS (South Africa), and TESTSAFE (Australia) criteria.
WOLONG's industrial three-phase induction and permanent magnet synchronous motors are critical components in heavy-duty machinery. These motors drive systems globally, from ventilation networks to high-pressure pump sets.
Highly volatile operating environments require positive pressure (YZYKS series) or explosion-proof (YBX5/YBBPX series) designs to prevent atmospheric gas ignition.
Underground operations utilize flameproof YBK3 and YBS/YBSD series motors to drive conveyor belts and ventilation fans, withstanding heavy dust, moisture, and mechanical shocks.
High-efficiency WE4 and WE3 series low-voltage asynchronous motors operate continuously in pump setups, reducing utility costs and carbon footprints.
A breakdown of the component engineering behind WOLONG's industrial motor lineup.
The rotor features a squirrel cage design, utilizing cast aluminum produced via centrifugal casting or die-casting techniques. Molten pure aluminum is injected into the rotor core slots, creating a unified single-piece structure integrating the rotor bars and end rings.
For larger capacity motors, copper bar rotors are used. These benefit from secure bar fastening and end-ring welding. A high-speed protective retaining ring design helps ensure safe copper bar rotor operation at high rotational speeds.
Stator coils are constructed from polyester film and reinforced with glass cloth. They utilize low-powder or medium-powder mica tape with a high mica content.
Following the VPI (Vacuum Pressure Impregnation) process, the finished coil assemblies emerge. The winding insulation system is engineered to provide high electrical insulation, mechanical strength, moisture resistance, and thermal stability.
The motor frame design is developed using digital platforms for structural and fluid multi-physics simulation. This platform optimizes the frame structure, which is manufactured from high-strength cast iron or structural steel.
The structural frame configuration supports heat dissipation and mechanical shock absorption, helping control overall machine vibration and operating temperatures.
The low-noise fan cover system consists of a fan cover body, air guide cylinder, protective window, and a silencer plate. Its compact structure helps damp resonance-induced noise.
The side-oriented air inlet design helps prevent blockages near the rear of the motor, optimizing airflow and reducing noise from turbulent energy loss. Sound-absorbing lining materials help manage ambient motor noise, and an IP22 rating prevents contact with the fan blades.
WOLONG electric motors comply with major international certifications, allowing installation in standard and hazardous locations worldwide.
WOLONG is an ISO 9001 certified Ex motor manufacturer. Compliance with ISO standards supports consistency in production quality and international trade processes, verifying that motors and control equipment meet industrial specifications.
To verify mechanical and electrical compliance with NEMA specifications, WOLONG conducts tests covering efficiency metrics, insulation resistance, starting current, torque profiles, vibration levels, and noise levels. Low-voltage models carry UL and CSA safety marks.
WOLONG's low-voltage, high-voltage, and explosion-proof motors hold IECEx and ATEX certification. These products are certified for safe operation in hazardous atmospheres (gas, vapors, and dust) across Europe and globally.
WOLONG holds TESTSAFE coal product certification, enabling export of underground mining motors to Australia and neighboring regions, supporting compliance with local environmental and safety requirements.
WOLONG's R&D centers focus on motor efficiency and digitization to support global sustainability goals.
Developing Permanent Magnet Synchronous Motors (PMSM) to achieve IE5 efficiency, reducing energy losses by up to 20% compared to standard induction models.
Integrating Variable Speed Drives (VSD) with the motor housing to optimize load adaptation and reduce external installation space requirements.
Installing embedded vibration and temperature sensors (such as OLI Ex sensors) to enable predictive maintenance and support cloud monitoring.
Evaluating bio-based resins, recycled steel laminations, and lead-free copper fabrication processes to minimize the carbon footprint of production.
To support international projects, Shaanxi Nanfang Motor and Wolong coordinate service and technical assistance through localized channels.
