Israel's industrial ecosystem is undergoing a major technological transformation, characterized by large-scale desalination initiatives (such as IDE Technologies projects in Sorek, Palmachim, and Ashdod), extensive offshore gas extraction (Leviathan and Tamar gas fields), and advanced chemical operations in the Negev Desert (Dead Sea Works). These installations require continuous power and extreme motor reliability. The demands on heavy industrial equipment are severe: high ambient temperatures, saline-corrosive environments, and high operational safety constraints.
This is where specialized AC High-Voltage (HV) induction and synchronous motors become essential. Engineered to handle operations between 3kV and 11kV, these motors power massive high-pressure intake pumps, large-scale gas compressors, and heavy cooling towers. By integrating international manufacturing capabilities with local engineering requirements, we supply reliable powertrain solutions designed specifically for Israel's key industrial sectors.
Explore our main selection of medium and high-voltage AC electric motors configured for Israeli industrial infrastructure standards, featuring low starting currents, high efficiency, and robustness against corrosive environments.
Shaanxi Nanfang Motor Technology Co., Ltd is the authorized distributor of Wolong. Wolong Electric Drive Group Co., Ltd was founded in 1984 and listed on the Shanghai Stock Exchange in 2002 (code SH600580). Over the past 30+ years, Wolong has built a global manufacturing footprint consisting of 3 major manufacturing bases, 39 factories, and 3 global R&D centers. Dedicated entirely to motor manufacturing and control system innovation, Wolong has become a leader in global market supply, tech R&D, and quality assurance.
WOLONG’s growth is built on integrating established global motor manufacturers. By incorporating leading European and American electric motor heritage brands into our global operational architecture, we deliver robust solutions across various industries.
Acquired in 2011, ATB is a leading European motor manufacturer. The group includes specialized brands like Morley (underground coal mining motors with a 130-year legacy) and Laurence Scott (known for low starting current systems used in naval generators and nuclear facilities).
Since 1882, Schorch has been a standard-setter in German heavy industry engineering, providing heavy-duty drive systems for petrochemical and oil & gas operations, marine shipbuilding, and municipal water management systems.
Brook Crompton's energy-efficient designs (W & 10 series) and the integration of General Electric’s (GE) Commercial and Industrial Motors division in 2018 have expanded our high-voltage portfolio to cover international NEMA and IEC standards.
Every medium and high-voltage AC electric motor is designed to meet strict operating tolerances and maximize uptime. Here is a detailed look at our core component architecture:
Our rotors use squirrel cage designs configured for high-torque startups. Centrifugal aluminum casting and high-pressure die-casting processes integrate the rotor bars and end rings, creating a single-piece construction that resists thermal distortion and mechanical stress.
For high-capacity, heavy-duty applications, we construct copper bar rotors with induction-brazed end rings. High-speed running models feature carbon fiber or alloy containment rings to protect the rotor head under high centrifugal forces, ensuring long-term bearing and rotor integrity.
The stator coil is insulated with high-grade, double-wrapped polyester film and reinforced with woven glass-cloth mica tapes. After winding, the stator core undergoes a complete Vacuum Pressure Impregnation (VPI) cycle using solventless epoxy resin.
This process cures the stator into a moisture-resistant, chemically inert structure. The finished stator has excellent dielectric strength, high thermal dissipation properties (Class F standard, Class H upgrade options), and resistance to environmental moisture, preventing partial discharges under high-voltage stresses.
Using digital simulation platforms (FEA structural analysis and CFD thermal fluid modeling), the motor frame structures are optimized for strength and heat dissipation. Cast iron (minimum Grade GG25) or heavy fabricated structural steel provides rigid support for the core.
This design maintains alignment under high torsional startups, minimizes natural resonance issues, and protects against external shocks, keeping operational vibration levels well within ISO 10816 standards.
Our noise reduction design features an aerodynamic intake profile, silencer baffles, and non-turbulent air direction guide channels. By integrating sound-deadening insulation, noise generation is reduced without restricting cooling airflow.
The entire housing meets IP22 or IP55 specifications, preventing contact with moving parts. This allows high-velocity cooling air to circulate quietly over the cooling fins, protecting municipal and plant working zones from noise pollution.
Exporting industrial systems to Israel requires strict compliance with international safety and quality standards. Our product catalog is verified by major testing houses, allowing seamless integration into projects with strict compliance needs:
Explosion proof certification for EU and Mediterranean hazardous zone classifications.
Verification of North American electrical standard safety and performance parameters.
Full conformance with European Union health, safety, and environmental protection rules.
Compliance with core quality standards and manufacturing process controls.
Our motors are manufactured in ISO 9001 certified facilities. For applications in explosive atmospheres, we offer motors certified under both IECEx and ATEX. These motors feature robust containment frameworks and strict temperature classifications (T3, T4, T5, or T6), making them suitable for refineries, oil platforms, and gas terminals.
We also provide a complete range of NEMA standard motors, certified by UL and CSA, alongside IEC standard models. This dual engineering capability ensures that whether your project is built to European or American design criteria, our products will drop into place without alignment or voltage issues.
Through our TestSafe certified mining motors, we support demanding underground extraction and processing lines. Our marine motors, certified by DNV, Lloyd's Register, and ABS, are designed for the corrosion challenges of offshore gas fields and coastal port infrastructure, featuring specialized anti-corrosion coatings and salt-spray resistant seals.
High-voltage motors must be configured for the specific operating conditions of their deployment location. Here is how we support Israel's primary industries:
Challenge: Continuous operation, high humidity, salt-spray exposure, and high pressure requirements for reverse osmosis membranes (e.g., Sorek II).
Solution: YKS water-cooled high-voltage motors with marine-grade double-barrier paint systems, anti-condensation space heaters, and duplex stainless steel shaft upgrades to prevent corrosive wear.
Challenge: Hazardous gas atmospheres (Zone 1 / Zone 2), high-torque loads, and thermal stress on compressor shafts.
Solution: TAW and YBK3 flameproof, increased safety synchronous/asynchronous motors. These units prevent electrical arcs and sparks from contacting ambient gas mixtures, meeting strict ATEX / IECEx requirements.
Challenge: Fine phosphate and potash dust, high desert temperatures, and abrasive wear on bearings.
Solution: IP55/IP66 enclosure ratings, labyrinth bearing seals, and Class H insulation derated for Class F temperature rises, ensuring reliable operation in harsh environments.
Today's competitive landscape requires a balance of engineering quality and cost efficiency. Manufacturing high-voltage motors in China offers significant advantages in lead times, material sourcing, and production capacity:
Vertically Integrated Supply Chains: By utilizing local steel mills for high-permeability silicon steel and operating dedicated in-house copper wire drawing lines, we maintain complete control over raw materials. This integration reduces delays and stabilizes costs, helping us mitigate global supply chain fluctuations.
Advanced Production Automation: Our facilities feature robotic stator winding, automated VPI chambers, and CNC machining centers. This automation ensures precision, reduces human error, and allows us to offer shorter manufacturing lead times than traditional Western competitors.
Full-Load In-House Testing: Every motor undergoes testing before dispatch. Our testing centers can perform full-load tests up to 15MW, measuring vibration, noise, temperature rises, and harmonics under simulated operating conditions to guarantee field performance.
