Deploying safety-assured low-voltage electric motor units engineered for high-precision operations in harsh petrochemical, pharmaceutical, and chemical refinery plants across major Japanese industrial centers.
The Japanese industrial market operates under some of the world's most rigorous mechanical and electrical safety guidelines. Explosion-proof environments—ranging from chemical processing complexes in Chiba, Kanagawa, and Yokkaichi to municipal wastewater treatment facilities and LNG importing terminals—require absolute dependability. Historically governed by the strictly local Technology Institution of Industrial Safety (TIIS) guidelines, Japanese engineering firms and plant operators are increasingly adopting international IECEx and ATEX standards to facilitate seamless global project designs.
To bridge the gap between traditional Japanese specifications and global safety standards, modern plant operators demand highly adaptive, high-efficiency motors (IE3, IE4, and IE5 ratings) designed to perform reliably under variable frequency control (VFD) without overheating in restricted environments.
Shaanxi Nanfang Motor Technology Co., Ltd. is the premier authorized global distributor for Wolong Electric Drive Group Co., Ltd. Founded in 1984 and listed on the Shanghai Stock Exchange in 2002 (code SH600580), Wolong has advanced to become a dominant global force in industrial electric drives.
With a robust framework of 3 major manufacturing bases, 39 state-of-the-art production factories, and 3 localized R&D hubs worldwide, Wolong is uniquely positioned to deliver reliable safety motors that meet the rigorous engineering standards expected by Japanese and international procurement companies.
Every single motor line is tested to conform with complex global safety marks. Our variable frequency (VFD) setups and standard induction models are certified for Zone 1, Zone 2, Zone 21, and Zone 22 applications.
To support Japan’s stringent Energy Conservation Act, we provide IE3, IE4, and IE5 ultra-high-efficiency ratings, lowering operational expenses and cutting electricity grid draw substantially.
From standard horizontal frame designs to complex tunneling, mining, and customized high-voltage motor packages, our engineering team tailors motor mounts, shaft dimensions, and electrical outputs.
As a pivotal node in the global industrial drive supply chain, Wolong’s production plants operate under the digitalised Factory 4.0 paradigm. This manufacturing system integrates robotic precision winding, computer-controlled rotor dynamic balancing, automated Vacuum Pressure Impregnation (VPI), and real-time Quality Management Systems (QMS).
For Japanese partners, this Translates into a highly resilient and cost-optimized supply chain. Through modern smart logistics systems, real-time dispatch tracking, and centralized manufacturing coordination, we can compress manufacturing lead times by up to 30% compared to traditional regional builders, assuring safety-critical drives arrive on site precisely when needed.
By acquiring and integrating the world's most trusted electrical engineering names, Wolong has combined decades of European and American legacy expertise with modern high-volume Chinese manufacturing precision.
Acquired in 2011, ATB is a leading European motor manufacturer. This brand includes legendary mining division Morley (with 130 years of underground motor expertise) and Laurence Scott, renowned for low-starting-current naval and power plant generators.
Boasting over a century of technology development, Brook Crompton is a global pioneer in energy-efficient AC electric motors, specifically the signature high-durability "W" and "10" series engineered for hazardous zones.
Founded in 1882, Schorch sets the global benchmark for high-power, custom-engineered drive systems operating in heavy-duty petrochemical, waste management, and heavy tunneling operations.
Partnered with Wolong since 1999, OLI dominates the global industrial vibration motor and safety sensor markets, producing robust components for bulk material transport in explosive atmospheres.
Joining the Wolong family in 2015, CNE Nanyang is China's largest specialized explosion-proof scientific research and production group, catering directly to oil, gas, nuclear power, and marine fields.
Integrated into Wolong in 2018, General Electric’s medium and low-voltage industrial motor division provides vast technological support, enhancing our heavy-duty engineering capacity for materials handling and mining projects.
The core electromagnetic coils are wrapped using high-performance polyester film coupled with glass-cloth backing, integrated with medium-to-high powder mica tape. Through our closed-loop Vacuum Pressure Impregnation (VPI) system, the wound stators undergo complete epoxy penetration. This manufacturing sequence ensures high dielectric resistance, excellent thermal conduction, high mechanical strength, and moisture-proofing for high-humidity Japanese coastal facilities.
We utilize cast aluminum rotors constructed via automated centrifugal casting or high-pressure die-casting, fusing the rotor bars and end rings into a robust single-piece structure. For heavy-duty low-voltage applications with high startup torque loads, we employ high-grade copper bar rotors welded via automated CNC induction equipment. Integrated high-speed retaining rings secure the rotor assembly, assuring minimal dynamic imbalance and excellent operating life under continuous heavy vibration loads.
Our motor frames are engineered using multi-physics structural and fluid thermal simulation systems, utilizing high-grade cast iron or structural carbon steel. Coupled with our low-noise fan cover system containing internal silencer plates, air guide cylinders, and side-mounted air intakes, the design minimizes acoustic feedback caused by high-velocity cooling air. Rated at IP22 and IP55 options, the mechanical layout safely isolates critical rotating parts from direct human contact while maximizing heat-rejection rates.
The low-noise ventilation system integrates sound-absorbing composite sheets to redirect sound paths away from reflecting walls. This structure keeps noise output significantly below standard limits specified by industrial health guidelines, even during hard direct-on-line (DOL) starts or variable high-speed operations.
To support global projects designed by Japanese EPC contractors, our AC low voltage motors comply with every major certification agency worldwide, assuring hassle-free field inspections.
