Explore our top-tier industrial electric motors engineering high-efficiency performance for hazardous locations and industrial automation environments.
In modern heavy industry, the transition toward high-speed three-phase AC motors is key to optimizing mechanical systems. Demanding operations like chemical processing, power plants, and underground mining require equipment that minimizes size and weight while achieving superior rotational speeds and torque. Today's industrial motors utilize advanced electromagnetic design, precision structural VPI (Vacuum Pressure Impregnation) treatments, and integrated thermal-fluid dynamics to guarantee long-term operational survival.

A broad product line covering low-voltage, medium-voltage, and high-voltage three-phase motors. These designs meet the needs of varying industries, load dynamics, and hazardous areas.
Integrating R&D networks with century-old industry brands to deliver advanced engineering quality.
Wolong has established motor and drive control R&D centers in China, Europe, and Japan, and established a central research institute in Shanghai. It is committed to research on motor and control technologies, with several products leading the international market.
Wolong owns leading domestic brands such as Nanyang Explosion, alongside internationally renowned century-old brands including Brook Crompton, Morley, Laurence Scott, Schorch, and ATB. This delivers high brand reputation and service networks in oil, gas, and mining.
As a leading motor manufacturer, Wolong has significant advantages in explosion-proof performance, reliability, and durability. Widely utilized in demanding oil, chemical, and coal mining operations, our products pass ATEX, IECEx, CU-TR, and other authoritative certificates.
How Wolong integrated premier global motor technologies to build a world-class manufacturing powerhouse.
In 2011, WOLONG acquired 97.94% of the Austrian ATB Group, one of the three major European motor manufacturers, becoming its actual controller. This acquisition added Morley (with nearly 130 years of underground coal mining expertise) and Laurence Scott (renowned for low starting current designs and naval generators) to the group's brands.
Brook Crompton joined the WOLONG group, bringing over a century of mastery in motor technology and design. Known for developing energy-efficient low, medium, and high-voltage AC motors (such as the premium Brook Crompton 'W' and '10' series), they provide reliable drive packages for harsh and hazardous environments.
Acquired by WOLONG in 2011, Schorch has set high standards for premium heavy-duty drive systems since 1882. Schorch provides motor technologies globally across oil and gas, chemicals, power generation, water management, steel processing, tunnels, and shipbuilding industries.
Wolong partnered with OLI, a leading global name in vibration motors. In 2015, China's largest explosion-proof research and production base, Nanyang Explosion-Proof Group (CNE), joined Wolong. This integration expanded the group's capacity for high-voltage and low-voltage flameproof motors used in oil, coal, metallurgy, and nuclear power fields.
In 2018, General Electric (GE) industrial motor division entered a deep strategic cooperation with WOLONG. As a historic manufacturer of commercial and industrial electrical systems, GE's integration with Wolong strengthens global sales, service networks, and technology capabilities across heavy processing industries.
We maintain international quality certifications to help cross-border purchasers meet local regulatory requirements.

WOLONG implements an all-in-one industrial chain strategy, securing primary safety and performance certs to ease market entry:
Premium raw materials and design practices built to withstand severe physical stresses.
Our squirrel-cage rotors rely heavily on centrifugal aluminum casting or die-casting techniques. This integrates rotor bars and end rings, delivering high mechanical strength and torque properties. For larger capacity systems, copper bar rotors are used with high-integrity welding. A retaining ring design is added to high-speed models to ensure stability against centrifugal forces.
Our stator coils are constructed using polyester film reinforced with glass cloth and high-mica-content tapes. The complete stator assembly undergoes Vacuum Pressure Impregnation (VPI), turning into a cured unit that offers high electrical insulation, mechanical strength, moisture resistance, and thermal stability under cycling loads.
Designed using digital structural and fluid multi-physics simulation platforms, the frame uses high-strength cast iron or structural steel. It offers generous thermal dissipation and vibration isolation margins. This lets the assembly absorb mechanical shocks, run with lower temperature rises, and maintain low noise levels.
This compact system integrates a fan cover body, air guide cylinder, protective window, and silencer plate. Side-located air inlets optimize airflow, avoiding obstructions behind the motor and reducing turbulence noise. Sound-absorbing lining inside dampens operational frequencies, and an IP22 rating prevents accidental contact with the blades.
Discover how Shaanxi Nanfang Motor and Wolong optimize costs and support localized operations.
Working with Wolong allows us to leverage China's deep raw material supply chains. By sourcing high-grade silicon steel sheets, copper windings, and specialized castings directly from verified partners, we mitigate cost fluctuations. Our 39 global factories allow regional allocation of projects to balance delivery schedules and avoid high shipping costs.
