Authorized Elite Distributor of Wolong Electric Drive Group Co., Ltd
Shaanxi Nanfang Motor Technology Co., Ltd serves as the premier authorized global channel partner and distributor of Wolong. Founded in 1984 and listed on the Shanghai Stock Exchange in 2002 (code SH600580), Wolong Electric Drive Group Co., Ltd has established itself as the absolute vanguard in global electric drive, power transmission, and motor manufacturing technologies.
Through more than three decades of aggressive expansion, strategic brand acquisitions, and dedicated technological iteration, Wolong now coordinates an unparalleled international network consisting of 3 main manufacturing bases, 39 advanced manufacturing factories, and 3 state-of-the-art R&D centers positioned globally. This infrastructure allows us to serve industrial giants in oil & gas, petrochemicals, mining, power generation, and automation, offering optimized solutions for three-phase vibration configurations, explosion-proof environments, and ultra-high-efficiency installations.
Deploying customized mechanical setups across 58+ countries, backed by international certifications and extensive proprietary research networks.
Through strategic global acquisitions and technical integration, Wolong brings together centuries of European, American, and Asian engineering heritage.
In 2011, WOLONG successfully acquired a 97.94% stake in the Austrian ATB Group, positioning the company as the absolute controller of three major European motor manufacturing giants. This consolidation integrated Morley, with its 130-year legacy of engineering explosion-proof underground coal mining motors, and Laurence Scott, celebrated for low starting current configurations and high-grade generators used by British naval vessels and nuclear power plants.
This was followed by the inclusion of Brook Crompton Motors, the historical pioneer of high-efficiency motor standardizations ("W" and "10" series), and Schorch (est. 1882), a premier German developer of heavy industrial drive systems for high-pressure oil & gas extraction and maritime environments. In 2015, China's research powerhouse, Wolong Electric Nanyang Explosion-proof Group Co., Ltd (CNE) joined the collective, followed by a monumental commercial partnership in 2018 with General Electric (GE), providing additional technological scalability across heavy industries worldwide.
In global materials processing, 3-phase vibration motors act as the primary kinetic source for vibratory feeders, screens, and separators. Operating on unbalanced eccentric weights, these motors transform rotational torque into controlled linear or circular harmonic oscillations.
From dry-bulk classification in Western Australian iron mines to coal flow control in North American rail terminals, high-capacity vibration motors must function with up to 99.9% duty-cycle reliability in extremely dusty, abrasive environments.
Chemical plants, grain storage hubs, and petrochemical labs encounter flammable vapors or explosive dusts daily. Sourcing high-performance vibration exciters that feature certified explosion-proof (Ex d, Ex tb) architectures is critical to operational safety.
China's industrial motor landscape has transitioned from high-volume production to a global leader in high-precision, premium-quality engineering. Backed by fully integrated supply chains, Chinese manufacturers can source specialized magnetic steels, copper wire, and heavy cast-iron housings locally, maintaining cost efficiencies that cannot be matched internationally.
Shaanxi Nanfang Motor Technology Co., Ltd leverages Wolong's vast production ecosystem to deliver advanced industrial drive systems. Our facilities feature:
Through a joint partnership established in 1999 with OLI Vibration Motors, the global leader in mechanical vibrator design, Wolong has combined Italian engineering with China's production capacity, offering unmatched performance per dollar.
Every 3-phase vibration motor and drive undergoes exhaustive load testing, insulation resistance validation, and sound profile calibration before shipment.
The rotor features the squirrel cage design, with cast aluminum rotors being widely utilized. These rotors are produced using either centrifugal aluminum casting or die-casting techniques, where molten pure aluminum is poured into the slots of the rotor core, resulting in a single-piece construction that integrates the rotor bars and end rings. The structural integrity and manufacturing process of cast aluminum rotors guarantee the motor rotor's reliability, and also endow the motor with outstanding torque properties. For larger capacity motors, copper bar rotors are employed, which benefit from dependable bar securing and end ring welding procedures. Additionally, the protective ring design of high-speed motors further ensures the reliable operation of the copper bar rotor.
The coil is crafted from polyester film and reinforced with glass cloth, utilizing either low-powder mica tape with a high mica content or medium-powdered mica tape with an abundance of mica. Following the VPI (Vacuum Pressure Impregnation) process, a pristine white coil emerges from the production line. After the billet is extracted from the wire, it proceeds through the VPI process to transform into a finished unit. The winding and insulation are meticulously engineered to provide exceptional electrical performance, mechanical strength, resistance to moisture, and thermal stability.
The motor frame employs a fully digital platform for structural and fluid multi-physics field simulations. This simulation platform retains the original patent's structure and design, utilizing mature, high-strength cast iron (or steel as an alternative). The frame boasts exceptional structural redundancy, outstanding heat dissipation properties, and ample inherent frequency isolation margins for the entire machine. It is engineered to endure significant mechanical shocks, maintain a superior vibration level, and ensure a lower temperature increase in the motor.
The low-noise fan cover system comprises a fan cover body, an air guide cylinder, a protective window, and a silencer plate. Its compact structure and lightweight design facilitate vibration reduction. The air inlet is situated on the side, which optimizes the avoidance of obstacles behind the motor, minimizing adverse effects on ventilation and reducing noise caused by energy loss during propagation path changes. The system also incorporates sound-absorbing materials that absorb noise, thereby lowering the overall motor noise. Additionally, the fan cover is rated IP22, ensuring that hands cannot come into contact with the fan.
Adhering to a comprehensive marketing strategy for the electric motor and the entire industry chain: WOLONG has secured the majority of product certifications, enabling it to penetrate the international market.
Our commitment to global standards includes the following key engineering and trade frameworks:
WOLONG's diverse range of motors finds application across a multitude of industrial sectors, serving equipment such as fans, water pumps, compressors, and engineering machinery. These motors are integral to various industries, including ventilation and refrigeration, construction, oil and gas, petrochemicals, coal chemistry, metallurgy, electric and nuclear power, maritime, and industrial automation. Our mission is to deliver optimal solutions and services to our customers.
Operating on shaker decks and vibrating screens to isolate coal grades. The inclusion of the Morley mining motor line provides the required dust-ignition-proof protection for underground work faces.
Utilizing flameproof (Ex d) motors, such as the YBX3 and YE5 series, to drive heavy fluid compressors and pumps safely in Zone 1 and Zone 2 environments.
Driving rotary bin activators and vibratory discharge cones, preventing material bridging in agricultural and cement silo structures.
Sourcing three-phase vibration motors or explosion-proof induction drives requires analyzing key physical and electrical characteristics:
1. Active Smart Monitoring: Modern plants are shifting to predictive maintenance. Implementing vibration sensors directly onto the motor housing enables real-time bearing wear, thermal load, and axis deviation tracking.
2. Transition to IE4 & IE5 Efficiency: With strict carbon compliance standards worldwide, industries are replacing legacy motors with premium-efficiency synchronous and asynchronous models to reduce long-term energy consumption.
3. Advanced Materials Research: Stators using high-grade polyester film reinforced with glass cloth and high-mica tapes withstand high voltage fluctuations and temperature rises (Class H insulation systems).
