Direct Factory Supply for OEM & ODM Applications Across Israel
In modern industrial engineering, continuous duty (IEC 60034-1 S1 rating) represents the ultimate benchmark for electric motor performance. S1 duty dictates that an electric motor must operate at a constant load for an indefinite period without exceeding its thermal equilibrium limit or suffering insulation degradation. When deployed in Israel’s demanding industrial hubs—ranging from high-salinity coastal seawater reverse osmosis (SWRO) desalination facilities in Ashkelon and Sorek to extreme heat agricultural pumping in the Negev and chemical processing at the Dead Sea—standard off-the-shelf AC induction motors frequently experience premature thermal breakdown, bearing seizure, and insulation fluting.
As a premier global OEM/ODM manufacturer and direct exporter serving Israeli original equipment manufacturers (OEMs), engineering procurement contractors (EPCs), and plant operations teams, Hoyer VMS Group combines over five decades of electromechanical application expertise with custom-engineered motor architectures designed specifically for the environmental and electrical grid requirements of the Eastern Mediterranean.
Designed with Class H vacuum pressure impregnated (VPI) insulation system, operating restricted to Class B temperature rise (80K max), allowing continuous duty at ambient temperatures reaching up to 50°C without thermal derating.
Multi-stage surface treatment complying with ISO 12944 C5-M High Marine Standard. Designed to withstand airborne salt fog along Israel's coastline and corrosive bromide gases at the Dead Sea.
Reinforced phase insulation, insulated non-drive end (NDE) bearings (SKF INSOCOAT), and shaft grounding brushes to completely eliminate high-frequency stray currents and bearing fluting.
Industrial machinery deployed across Israel must comply with rigorous electromechanical standards, including SI 60034 alignment, IEC 60034-30-1 efficiency classifications, and European EcoDesign Directives (EU 2019/1781). Hoyer AC continuous duty induction motors are engineered to meet and exceed these specifications, offering seamless drop-in mechanical replacement for standard IEC frames (B3, B5, B14, B35) and NEMA frame dimensions (140T through 449T).

Israel's industrial ecosystem is recognized globally for advanced engineering, precision agriculture, chemical extraction, and intense water infrastructure development. continuous duty AC motors form the electromechanical backbone of these mission-critical facilities, operating under unique local environmental stressors.
Desalination facilities across Ashkelon, Sorek, Hadera, and Palmachim require high-power 3-phase induction motors driving continuous high-pressure pumps. Our IE4/IE5 cast iron motors with 316L duplex stainless steel shafts and C5-M coatings deliver zero-downtime performance in high-humidity, high-salinity coastal environments.
From the Jezreel Valley to the arid southern Negev desert, Israel's agricultural infrastructure depends on booster pumps operating continuously for months. Hoyer S1 continuous duty motors handle wide voltage fluctuations (380V to 415V ±10% at 50Hz) and withstand intense solar radiation and high ambient ground heat.
Extraction plants operating at the Dead Sea present extreme challenges: fine mineral dust, high ambient temperatures exceeding 48°C, and aggressive chemical vapors. We supply custom explosion-proof (Ex db / Ex eb) and totally enclosed fan-cooled (TEFC) AC motors with IP66 dust-tight sealing.
Semiconductor fabrication plants in Kiryat Gat and tech manufacturing hubs in Yokneam require air handler motors operating with minimal acoustic and mechanical disturbance. Our precision-balanced rotors achieve Vibration Grade B (IEC 60034-14) to eliminate micro-vibrations in cleanroom environments.
Standard motors often fail to satisfy precise spatial, mechanical, or electrical constraints. As an established OEM/ODM manufacturing partner, Hoyer provides complete custom-design capabilities from initial CAD thermal modeling to batch production and rapid export fulfillment.
Technical guidance and commercial clarity for Israeli procurement officers, mechanical engineers, and equipment importers.
Motors imported into Israel must align with Israeli Standard SI 60034 (which harmonizes with IEC 60034-1) and energy efficiency regulations aligning with IEC 60034-30-1. Standard low-voltage motors from 0.75kW to 1000kW are generally required to achieve at least IE3 (Premium Efficiency) or IE4 (Super Premium) levels. Full documentation, CE certificates, and ISO 9001 factory test reports are provided with every Hoyer export shipment.
Standard motors are rated for 40°C ambient limits and suffer immediate power derating in extreme heat. Hoyer Levant-Spec motors utilize Class H insulation (rated to 180°C) but operate under Class B temperature rise limits (maximum 80K rise). This built-in thermal reserve allows continuous S1 operation at 50°C ambient temperatures without derating motor power output or shortening insulation lifespan.
Variable Frequency Drives (VFDs) generate high-frequency Common Mode Voltage (CMV), leading to electrical discharge machining (EDM) currents through motor bearings. For VFD-driven continuous duty applications above 110kW, Hoyer fits SKF INSOCOAT insulated bearings on the non-drive end (NDE) and a conductive micro-fiber grounding ring on the drive end (DE) to safely divert stray shaft voltage.
Yes. With over 70,000 standard motors held in strategic global inventories and dedicated fast-track OEM modification centers, we provide custom shafting, specialized painting, and sensor integration within accelerated turnaround windows, offering direct sea freight shipping to Haifa and Ashdod ports, or air freight to TLV Ben Gurion Airport for urgent MRO replacement.
For installations located within 5 km of the Mediterranean coast, we recommend our ISO 12944 C5-M (Marine High) paint system. This involves a epoxy zinc-rich primer, epoxy intermediate coating, and polyurethane topcoat with a total dry film thickness (DFT) exceeding 320 microns to resist salt spray corrosion.
Yes. We offer a full range of explosion-proof continuous duty AC motors certified under ATEX and IECEx standards for Zone 1, Zone 2, Zone 21, and Zone 22 hazards (Ex db, Ex eb, Ex ec, Ex tb), suitable for chemical refineries, fuel storage terminals, and Dead Sea mineral processing plants.
