Premium industrial drives certified for Austria's chemical hubs, refineries, and demanding gas storage systems.
Austria's industrial sector operates under some of the most rigorous environmental and safety guidelines in Europe. Key sectors such as petrochemical refining, deep tunnel ventilation, chemical synthesis, and underground mineral extraction demand motors that deliver maximum operational reliability while complying strictly with EU directives. Environmental elements—ranging from sub-zero Alpine winter temperatures in pump-storage hydro plants to critical atmospheres inside gas transportation nodes—necessitate top-tier AC high voltage explosion-proof motors.
For local operations, standard industrial equipment is not sufficient. Explosion hazards in zones with flammable gases, mists, vapors, or combustible dust require explosion-proof ratings under Directive 2014/34/EU (ATEX). Additionally, Austria's commitment to the European Green Deal shifts the technological baseline toward high-efficiency systems. Transitioning to IE3, IE4, and customized IE5 permanent magnet synchronous structures has become the standard mechanism to control operational costs and reduce carbon footprint under strict regulatory frameworks.
A global heavy-duty machinery collaboration bridging European motor engineering with state-of-the-art Chinese manufacturing.
Shaanxi Nanfang Motor Technology Co., Ltd. is the authorized global distributor of Wolong. Founded in 1984, Wolong Electric Drive Group Co., Ltd. successfully listed on the Shanghai Stock Exchange in 2002 (code SH600580). With over three decades of engineering innovation, Wolong now manages 3 major global manufacturing bases, 39 advanced factories, and 3 global R&D centers.
In 2011, Wolong significantly expanded its European capabilities by acquiring 97.94% of the Austrian ATB Group (Spielberg and Zeltweg manufacturing facilities), one of the three major motor manufacturers in Europe. This integration combined Austrian precision engineering with Wolong's global production resources. Today, the group's portfolio features world-renowned historical brands:
ATB possesses over a century of Austrian engineering heritage. Laurence Scott specializes in low-starting-current engineering solutions, having provided generators and critical drive units for British naval vessels and nuclear facilities.
Founded in Germany in 1882, Schorch sets quality standards in oil & gas and petrochemical systems. Brook Crompton is a pioneer in energy-efficient motors, offering comprehensive low-to-high voltage variable frequency drive packages.
As one of China's largest scientific research and production bases for explosion-proof drives, CNE's technologies are widely implemented in heavy industrial installations, mining, and high-safety military projects.
Ex-proof structural design, premium insulation technologies, and Smart IoT diagnostics engineered to withstand extreme conditions.
The coils are insulated with high mica-content tapes reinforced with polyester film and glass cloth. Using Vacuum Pressure Impregnation (VPI), the finished stator assembly provides excellent moisture resistance, high mechanical strength, and thermal stability in humid Alpine valleys.
Utilizing squirrel-cage configurations with centrifugal cast aluminum or die-cast techniques to form a rigid, single-piece core. For mega-scale high voltage units, custom copper bar designs are used with reinforced end-ring welding, protecting against thermal expansions under frequent starting sequences.
Motor frames are simulated via structural and fluid dynamics models to optimize heat dissipation, vibration margins, and structural integrity. Paired with an IP22 side-inlet silencing fan cover system, it keeps operating noise low while preventing structural resonance.
Balanced dynamics utilizing centrifugal cast aluminum or copper bar welding designed to resist high torque fluctuations.
Polyester film wrapped with glass cloth and impregnated under high pressure to ensure reliable dielectric performance.
High-strength cast iron frame modeled to isolate frame frequencies and survive high thermal stress.
Side-inlet aerodynamic geometry lined with acoustic absorption elements to minimize energy loss and noise.
Streamlined safety certifications and dedicated engineering support to ensure seamless compliance for your next project.
WOLONG's industrial footprint is backed by international certifications that allow direct integration into Austrian and global supply chains. With active engineering centers across Austria (ATB Spielberg/Zeltweg), Germany (Schorch, Mönchengladbach), and China, we deliver certified motors ready for immediate operation.

By combining our China Factory 4.0 production infrastructure with Austrian technical offices, we offer a balanced supply chain. Customers benefit from local engineering consultations, compliance verification, and fast-response technical support alongside the cost efficiency and scale of our primary manufacturing facilities.
Ex-proof motors and synchronous system solutions designed to integrate with major industrial applications.
Technical answers regarding installation, compliance, and custom engineering in Europe.
All motors intended for hazardous locations in the Austrian market comply with European Directive 2014/34/EU (ATEX) and the international IECEx system. Wolong works with recognized notified bodies (such as Nemko, PTB, and CESI) to issue certificates verifying Ex d (flameproof), Ex e (increased safety), Ex p (pressurized), and Ex tD (dust ignition protection) markings.
Wolong's acquisition of the Austrian ATB Group combines ATB's historical design archives and engineering expertise with Wolong's global production capacity. This integration provides domestic customers with local technical support and engineering offices in Austria, alongside cost-efficient manufacturing capabilities.
We offer specialized engineering packages for extreme Alpine conditions. These include anti-condensation space heaters, low-temperature grease and seals rated down to -40°C, custom protective paints resistant to high humidity, and reinforced bearings designed to handle high external structural vibrations.
Every stator processed via our Vacuum Pressure Impregnation (VPI) system undergoes standard quality control tests. This includes dielectric testing, dissipation factor measurement, and insulation resistance measurement to verify the stator's ability to resist high moisture, thermal stress, and voltage surges.
