Explore our certified heavy-industry asynchronous, permanent magnet, and flameproof electric motors. Custom engineered for extreme operational reliability.
Inheriting over five decades of electromechanical expertise from Italian powerhouses OME Motors (O.M.E. Motori Elettrici s.r.l.) and Elettrotecnica H. Orsatti, our manufacturing group represents the global benchmark in heavy industrial electric motor design.
Every industrial process demands tailored mechanics. We specialize in custom frame dimensions, special shaft extensions (tapered, double-extension, spline), non-standard voltage/frequency combinations (up to 15kV), and extreme environment thermal insulation systems.
Our flameproof and explosion-proof series are rigorously tested and certified under international standards including ATEX (2014/34/EU), IECEx, UL/CSA (Class I Div 1 & 2), and GOST-R. Designed for safe operation in explosive gas (Zone 1 & 2) and combustible dust (Zone 21 & 22) zones.
Engineered for subzero, marine offshore, and highly wash-down industrial environments. Featuring precision-machined labyrinth oil seals, dual-lip viton shaft seals, cast-iron seal plates, and anti-corrosive epoxy polyurethane paint systems tested to C5-M marine endurance specs.
In high-hazard process industries—such as offshore oil platforms, hydrocarbon processing, underground coal mining, and grain handling facilities—the electric drive motor is often exposed to a harsh combination of explosive gas/dust atmospheres and aggressive physical weathering. Achieving absolute operational safety requires dual-layer protection: Ex d / Ex de flameproof containment paired with true IP66 total dust-tight and heavy water jet resistance.
While standard industrial motors are rated IP55 (dust protected, water splash resistant), custom OEM IP66 motors guarantee complete protection against dust ingress (dust-tight) and protection against powerful water jets (100 liters per minute at 100 kPa pressure from a 12.5mm nozzle). This prevents moisture accumulation inside stator windings, eliminating insulation breakdown in humid or marine washdown environments.

Driven by global decarbonization mandates and Industry 4.0 automation, OEM electric motor sourcing is undergoing a dramatic shift. Key trends every procurement manager must evaluate include:
Historically, explosion-proof motors lagged in energy efficiency due to thick casting walls and high mechanical friction from flameproof seals. Modern FEA electromagnetic design allows OEM manufacturers to deliver IE4 Super Premium and IE5 Permanent Magnet Synchronous Motors (PMSM) within certified Ex d housings, reducing plant operating expenses by up to 18% annually.
Unplanned downtime in petrochemical plants can cost millions per hour. Procurement contracts increasingly specify pre-installed Ex-certified IIoT sensors (vibration, bearing temperature PT100s, winding thermistors, and air-gap monitoring). Real-time telemetry allows predictive maintenance without opening flameproof enclosures in hazardous zones.
Replacing mechanical gearboxes with direct-drive Permanent Magnet High-Torque Motors powered by Variable Frequency Drives (VFDs) is rapidly growing. OEM buyers require motor winders to incorporate reinforced insulated bearings (ceramic/hybrid ball bearings) and sinusoidal output filters to mitigate bearing fluting currents.
Global EPC contractors are standardizing on multi-certified dual-branded motors (e.g., simultaneous ATEX + IECEx + UL/CSA + CE marking). This enables global equipment manufacturers to build standard machine skids in Asia or Europe and export directly to North America or the Middle East without motor retrofitting.
The next generation of custom OEM explosion-proof drive systems focuses on ultra-lightweight alloys, advanced heat dissipation modeling, and permanent-magnet-assisted synchronous reluctance motors (SynRM).
Combining magnet-free rotors with extreme high-efficiency stator winding architecture. SynRM eliminates rotor losses completely, delivering cool-running operating temperatures that allow higher power density within compact Ex d flameproof frames.
Developing cryogenic steel housings, synthetic arctic grease lubrication, and internal automatic space heaters to ensure flawless cold-start torque in Siberian or Arctic LNG liquefaction terminals, alongside high-temp desert refinery installations.
3D-printed internal air-to-water cooling jacket channels (IC81W / IC611 cooling methods) integrated directly into high-voltage explosion-proof stator housings, maximizing heat dissipation while maintaining complete IP66 containment.
Explosion-proof motors powering offshore drilling mud pumps, crude oil transfer pumps, gas compressors, and refinery cooling towers. Our Ex d IIC T4 IP66 design resists hydrogen sulfide (H2S) gas corrosion and marine salt fog.
Driving chemical agitators, polymer reactors, and centrifugal blowers. Features special Viton mechanical seals, anti-acid epoxy coatings, and PT100 thermal sensors in both windings and bearings for absolute safety.
Group I Ex d I M2 mining motors built with heavy ductile iron housings capable of resisting falling rock impacts and continuous firedamp methane / coal dust exposure in mine ventilation fans and armored face conveyors.
Combustible dust atmospheres (Zone 21 & 22) require Ex tb dust-ignition-proof motors. IP66 seals prevent superfine organic dust from infiltrating bearing races, eliminating frictional hot spots and dust explosion risks.
