Engineered for extreme reliability, functional optimization, and global energy efficiency compliance.
Electric motors represent the heart of global heavy industry, accounting for approximately 45% to 50% of the world's total electricity consumption. As international emissions standards tighten under Net Zero 2050 directives, energy-efficient electric motors have evolved from operational optimizations into legal imperatives. The transition from legacy IEC standard motors to IE4 (Super Premium Efficiency) and IE5 (Ultra-Premium Efficiency) is reshaping industrial procurement requirements across the globe.
For heavy industrial sectors, including oil and gas refining, chemical manufacturing, deep mining operations, and utility power generation, selecting an optimal energy efficient motor translates directly to operational cost reductions. In addition to reducing systemic carbon footprints, these next-generation motor systems offer superior thermal control, lower mechanical vibrations, and significantly extended operational life cycles, resulting in lowered Total Cost of Ownership (TCO).
Modern electric motor infrastructure focuses on maximizing efficiency rates over variable load demands. Chinese manufacturers, using advanced rare-earth components and automated tooling, now lead the international market in making high-end custom motor systems widely accessible.

Industrial drive solutions engineered to operate reliably in hazardous locations and harsh process environments.
We supply explosion-proof motor systems certified by leading international testing bodies, ensuring safe installation in hazardous zones containing combustible gases, vapors, or dusts.
Offering a complete range of IE3, IE4, and IE5 asynchronous and permanent magnet motors, our products lower daily power usage while keeping installation dimensions compact.
From low-voltage flameproof motors to custom high-voltage non-sparking drive systems, we cover requirements across oil & gas, mining, water treatment, and industrial ventilation.
How Wolong integrated premier global motor brands to build an authoritative network of manufacturing and design expertise.
2011: The Acquisition of ATB Group (Austria)
WOLONG acquired 97.94% of the Austrian ATB Group (ATB motor), one of Europe's top three motor manufacturers. This acquisition integrated decades of Western European drive technology and incorporated specialized sub-brands including Morley (rugged coal mining motors) and Laurence Scott (high-power, low starting current systems).
Morley & Laurence Scott Heritage
With a history spanning nearly 130 years in underground mining, Morley represents a standard of durability in extreme underground atmospheres. Laurence Scott, a pioneer in supplying motors for naval vessels and nuclear power facilities, brought deep expertise in low starting current generators and motors to the group.
Integration of Brook Crompton
As an established name in electric motor design with over a century of experience, Brook Crompton joined the Wolong Group. Brook Crompton is recognized for high-efficiency motor innovations, including the "W" and "10" series low, medium, and high-voltage AC motors designed for harsh or hazardous environments.
Schorch Electric Motors (Acquired 2011)
Founded in Germany in 1882, Schorch specializes in heavy-duty drive systems for oil & gas, chemical processing, wastewater management, and tunnel ventilation. Its engineering integration strengthened the group's custom manufacturing capabilities for high-output, low-noise systems.
OLI Vibration Technology Partnership
Since 1999, Wolong has partnered with OLI to produce specialized industrial vibration motors and sensors. Today, OLI is a leading global supplier of industrial vibration equipment, serving bulk material handling, concrete compaction, and industrial sorting systems.
2015: CNE Nanyang Explosion-proof Group & 2018: General Electric (GE) Partnership
In 2015, China's largest explosion-proof research and production base, Nanyang Explosion-proof Group (CNE), officially joined Wolong. In 2018, Wolong acquired General Electric's (GE) commercial and industrial motor division, integrating GE's medium and high-voltage motor engineering experience into our international supply chain.
A look inside the materials, manufacturing processes, and design features that differentiate our industrial motors.
Built with squirrel-cage designs using centrifugal or high-pressure aluminum die-casting. The cast aluminum structure integrates the rotor bars and end rings, providing high starting torque. Larger capacity motors utilize copper bar configurations with welded end rings for high-speed reliability.
Windings use high-grade copper wire protected by polyester film and glass-fiber tape, built using low- or medium-powder mica tape. Coils undergo a comprehensive Vacuum Pressure Impregnation (VPI) process to ensure moisture resistance, mechanical strength, and high thermal stability.
Designed using multi-physics structural and fluid dynamic simulations. Cast in high-strength grey iron or fabricated steel, our frames provide excellent heat dissipation, rigid vibration dampening, and the structural integrity required to withstand mechanical shock in heavy industries.
Our fan covers combine high-efficiency air routing with built-in noise silencers. Using side-entry air inlets and sound-absorbing linings, this design reduces aerodynamic noise. The system is IP22 rated to prevent accidental contact with moving parts.
To support global supply chains, Shaanxi Nanfang and Wolong maintain certifications for major regional markets. Our motors comply with international quality, safety, and hazardous-area performance standards, enabling smooth import processing and plant commissioning.

Where our high-efficiency and explosion-proof motor systems are deployed globally.
In petroleum refineries and upstream extraction, explosion-proof motors (such as the YBX5 and YBXKK series) drive heavy compressors, multiphase pumps, and heat exchangers. These units are built to resist atmospheric corrosion and prevent internal sparks from igniting external gases.
Our specialized mining motors, built on the heritage of the Morley brand, drive coal shearers, scraper conveyors, and continuous haulage machinery. These systems are designed to operate under dust loading, moisture, and high starting-torque requirements.
Low-noise fan motor systems are designed for large cooling towers, smoke extraction fans, and industrial ventilation. Integrated Variable Frequency Drives (VFD) allow for precise speed adjustments, optimizing airflow while reducing energy draw.
