Engineered in compliance with AS/NZS 60079, IECEx, and MEPS high-efficiency standards. Ready for OEM/ODM custom shaft, mounting flange, and voltage configurations (380V/400V/415V 50Hz).
In modern process industries across New Zealand—ranging from massive dairy spray-drying powder towers in the Waikato to high-temperature geothermal power plants in the Taupo Volcanic Zone—industrial drive systems operate under extraordinary environmental and safety pressures. Choosing an OEM/ODM Explosion-Proof Low Voltage Electric Motor supplier requires far more than matching horsepower and frame size; it demands absolute compliance with the joint Australian/New Zealand standard AS/NZS 60079, severe ambient weather protection, and optimal electrical design for the local 415 Volt / 50 Hertz three-phase utility grid.
Combining over 50 years of Italian electromechanical heritage (O.M.E. Motori Elettrici s.r.l.) with advanced custom manufacturing, our explosion-proof low voltage motor lineup delivers unmatched operational safety in hazardous atmospheres classified under Zone 1, Zone 2 (Explosive Gas/Vapor), and Zone 21, Zone 22 (Combustible Dust). By offering flexible OEM/ODM modifications—including custom mechanical shaft machining, specialized mounting configurations (B3, B5, B14, B35), anti-corrosive C5-M marine coatings, and reinforced VFD-rated inverter insulation—we provide New Zealand plant managers, original equipment manufacturers (OEMs), and EPC contractors with high-efficiency, risk-free motor replacement and greenfield integration.

From South Island timber mills to North Island dairy evaporators, our explosion-proof motors are specifically engineered to withstand harsh local operating conditions.
New Zealand produces over 3% of global milk output. In spray-drying powder towers and bagged milk powder handling, fine organic dust poses severe explosion risks (Zone 21/22). Our Ex tb / Ex tc dust ignition-proof low-voltage motors featuring IP66 sealing and stainless steel hardware prevent dust ingress, withstand daily high-pressure chemical washdowns (CIP), and comply fully with dairy hygienic standards.
Operating in volcanic zones like Rotorua and Taupo exposes electric motors to high atmospheric concentrations of Hydrogen Sulfide (H2S), high ambient steam heat, and corrosive condensate. Our OEM geothermal-spec motors incorporate C5-M epoxy painting, fluororubber dual-lip shaft seals, anti-H2S stator varnish, and Class H insulation to ensure uninterrupted power generation and cooling tower pump reliability.
Sawmills in Northland and the Central North Island generate hazardous combustible wood dust and resinous vapors. OME’s low-voltage explosion-proof motors deliver high starting torque to handle heavy inertia wood chippers, band saws, and dust extraction blowers, preventing thermal overload and thermal ignition under continuous heavy load (S1 duty rating).
In coastal logistics hubs such as Port of Auckland, Port of Tauranga, and Lyttelton, fuel bunkering pumps and chemical loading winches operate in hazardous marine environments (Zone 1 Ex d IIB T4). Our flameproof motors offer IP66 saltwater tightness, stainless steel fasteners, and internal anti-condensation heaters to eliminate moisture build-up during maritime idle periods.
Extractive operations and chemical synthesis facilities across New Zealand utilize toxic and explosive compounds. OME custom-engineers explosion-proof drives with Ex d / Ex db flameproof enclosures, reinforced bearing housing, and customized mechanical face flanges for seamless drop-in fitment onto heavy mixers, slurry pumps, and mine ventilation fans.
WorkSafe New Zealand and local electrical safety inspectors require absolute verification for electrical equipment operating in hazardous locations. All explosion-proof motors supplied into New Zealand must carry accredited IECEx Certification of Conformity (CoC) or direct compliance with AS/NZS 60079.0 (General Requirements), AS/NZS 60079.1 (Flameproof Enclosures 'd'), and AS/NZS 60079.31 (Dust Protection 't'). OME guarantees full traceability with certified nameplates, localized test documentation, and flameproof joint clearance validation.
Under New Zealand’s Energy Efficiency and Conservation Authority (EECA) and GEMS regulations, industrial low-voltage motors must meet or exceed IE3 Premium Efficiency thresholds. To help New Zealand manufacturing operations achieve ambitious net-zero carbon targets, OME offers advanced IE4 Super Premium induction motors and IE5 Permanent Magnet Synchronous Motors (PMSC) that drastically cut annual kilowatt-hour consumption and operational thermal loss in continuously running pumps and fans.
Modern NZ industrial plants heavily adopt Variable Frequency Drives (VFDs) to optimize flow control and save energy. Operating explosion-proof motors on VFD power introduces high peak voltage spikes (dv/dt) and localized rotor heating. OME’s custom low voltage Ex motors feature inverter-duty reinforced magnet wire, insulated bearings (to eliminate shaft currents), and thermistor protection (PTC 130°C/150°C) linked to drive safety loops.
New Zealand’s unique maritime geography exposes equipment to high atmospheric salt content, high humidity, and intense ultraviolet radiation. OME incorporates high-grade cast iron (GG25/EN-GJL-250), polyurethane topcoats rated for C5-M high marine exposure, stainless steel hardware, and protected breather drain plugs to ensure 20+ years of maintenance-free mechanical life.
Combining over 50 years of electromechanical innovation with rapid custom manufacturing for demanding engineering contractors across New Zealand.
Originating from Brescia, Italy, OME Motors (O.M.E. Motori Elettrici s.r.l.) inherits decades of specialized European electromechanical expertise, producing robust explosion-proof drives for global industrial leaders including Eni, Shell, and ArcelorMittal.
We provide full technical flexibility: custom drive shaft dimensions, special keyways, non-standard mounting flanges (B3/B5/B14/B35), custom terminal box orientation (top, left, right), and tailored winding voltages (380V/400V/415V/690V).
Every motor undergoes stringent quality control prior to shipment, including 100% surge testing, flameproof gap micro-measurement, dynamic balancing (ISO 1940 Grade G1.0/G2.5), noise testing, and full load temperature rise testing.
