Through strategic worldwide acquisitions and technology partnerships, Wolong offers deep expertise under well-known industry brands.
Acquired in 2011, Austria-based ATB Motor Group stands as a key European motor designer. Under this label, Morley boasts a 130-year legacy in extreme underground coal mining, delivering high-performance explosion-proof underground equipment built to handle rigorous mining cycles.
Laurence Scott is respected globally for heavy-duty motors featuring exceptionally low starting currents, commonly used in nuclear applications and naval defense. Brook Crompton leads energy-efficient industrial AC motor designs, providing robust, low-maintenance motors for harsh conditions.
Dating back to 1882 in Germany, Schorch sets high standards in petrochemicals, oil & gas, and water management. Alongside OLI, the global leader in industrial vibration motors and sensors, Wolong provides complete system solutions for process control and bulk handling.
In 2018, General Electric's commercial and industrial motor division joined Wolong. CNE (Nanyang Explosion-Proof Group) is China's largest testing and production center for explosion-proof motors, supporting defense, nuclear power, and hazardous industrial pipelines.
Modern industrial operations face strict targets to reduce energy loss and cut operating costs. Global markets, including the EU under Eco-design Regulation 2019/1781, require high-efficiency performance for general-purpose three-phase induction motors. Our CE certified motors are designed to help operators transition smoothly to higher energy standards.
In hazardous locations like oil extraction platforms, LNG processing plants, and petrochemical lines, safety standards like ATEX and IECEx are non-negotiable. Wolong's three-phase asynchronous motors are built with robust flameproof enclosures, advanced cooling channels, and high-performance insulation systems to prevent ignition hazards while maintaining reliable power delivery.
Our industrial motors are certified by leading global agencies, allowing smooth integration into international markets and hazardous regions.

To overcome international trade barriers and meet diverse national grid standards, we offer a range of product compliance profiles:
A detailed look at the premium materials and design choices that ensure long operational life and durability.
Our squirrel-cage rotors feature robust cast-aluminum and copper-bar configurations. Cast-aluminum rotors are manufactured via centrifugal and high-pressure die casting to form integrated conductor bars and end rings, delivering stable startup torque. For larger, heavy-duty applications, copper bars are secured and welded to the end rings, supported by dynamic balance tuning to minimize vibration.
The stator windings are constructed using high-grade copper wires insulated with premium mica and polyester tape. The complete assembly undergoes a Vacuum Pressure Impregnation (VPI) process to seal the coils. This creates a solid winding structure with excellent moisture resistance, high dielectric strength, and reliable thermal dissipation, supporting stable Class F and Class H operation.
Designed using multi-physics simulation platforms, our heavy-duty motor frames are cast from premium gray iron or fabricated structural steel. The high-rigidity design features optimized cooling fins for heat dissipation, helping to absorb mechanical shock, isolate natural frequencies, and maintain alignment under heavy loads.
The ventilation system utilizes an aerodynamic fan cover, air guide cylinder, protection grilles, and sound-damping plates. By drawing air through side-mounted inlets, the system reduces turbulences and noise associated with air direction changes. Rated to IP22, the fan cover provides reliable protection against contact while ensuring constant cooling airflow.
We design our technology lines to support energy-efficient industries and advanced automation systems.
Deploying advanced permanent magnet assisted synchronous reluctance motors (PMaSynRM) to meet high-efficiency expectations and comply with strict carbon reduction rules.
Integrating compact vibration, temperature, and magnetic flux sensors directly onto the motor housing to enable predictive maintenance alerts, minimize downtime, and extend operating life.
Applying specialized ceramic and resin coatings to protect windings from high-voltage spikes, while optimizing internal airflows to ensure reliable performance in extreme environments.
Key technical details regarding CE marking compliance, installation parameters, and motor customizability.
