Wolong owns leading domestic brands such as Nanyang Explosion, as well as internationally renowned century-old brands, such as Brook Crompton, Morley, Laurence Scott, Schorch, ATB, etc., boasting peerless reputation in oil, gas, and mining.
As a prominent manufacturer, Wolong excels in explosion-proof performance, reliability, and durability, widely deployed in oil refineries, chemical complexes, and underground coal mines, fully certified by ATEX, IECEx, and CU-TR.
Accumulated with abundant assets and brilliant experiences in manufacturing, WOLONG started to reach for higher milestones. To become the leading manufacturer of AC motors & drives worldwide, WOLONG strategically acquired prominent overseas groups, bringing unprecedented engineering prowess under one umbrella.
ATB Group (Austria): In 2011, Wolong successfully acquired 97.94% of the Austrian ATB Group, one of the three major European motor manufacturers. This brought legendary heritage brands like Morley and Laurence Scott into the group. Morley, with a nearly 130-year history, is globally synonymous with ultra-reliable underground coal mining electrical equipment. Laurence Scott, a pioneer supplying motors for British nuclear power plants and naval vessels, has consecutively won the prestigious Queen's Award.
Brook Crompton Motors: Boasting over a century of mastery in motor design and innovation, Brook Crompton joined WOLONG to pioneer high-efficiency low, medium, and high-voltage AC motors, setting industry benchmarks for energy conservation.
Schorch & OLI: Established in 1882 in Germany, Schorch sets the gold standard for heavy-duty industrial motors across oil, gas, and power generation. Meanwhile, collaboration with OLI solidified global leadership in vibration motors (MVE) and explosion-proof vibration sensors.
Nanyang Explosion Protection & GE Industrial Integration: In 2015, CNE (China's largest explosion-proof research and manufacturing base) joined Wolong. In 2018, General Electric's (GE) commercial and industrial electrical motor business integrated into Wolong, reinforcing unparalleled engineering expertise across heavy industries worldwide.
International procurement managers across oil & gas, mining, and water treatment increasingly demand integrated drive systems that meet stringent international standards (ATEX, IECEx, NEMA) while offering lifecycle cost optimization and guaranteed supply chain continuity.
Leveraging fully digital multi-physics simulation platforms, automated robotic winding, and Vacuum Pressure Impregnation (VPI) systems, Wolong’s smart manufacturing bases deliver unmatched production scalability, strict quality consistency, and rapid lead times.
From offshore marine platforms and deep underground coal mines to hazardous chemical refineries and nuclear power installations, Wolong’s specialized motors are tailored to withstand extreme thermal, corrosive, and explosive environments.
Features squirrel cage designs utilizing centrifugal aluminum casting or die-casting for robust reliability and outstanding torque properties. Large capacity models employ high-grade copper bar rotors with protective rings for high-speed performance.
Coils are crafted from polyester film reinforced with glass cloth and high-mica content tape. Subjected to advanced Vacuum Pressure Impregnation (VPI), they deliver exceptional electrical performance, moisture resistance, and thermal stability.
Engineered using digital fluid and structural simulation platforms with high-strength cast iron or steel. Provides superior structural redundancy, excellent heat dissipation, and minimal vibration levels under heavy mechanical shock.
Comprises an air guide cylinder, silencer plate, and sound-absorbing materials to drastically reduce operational noise while ensuring IP22 safety compliance against accidental fan contact.
