Feature Exdb flameproof protection and IP66 enclosure provide safe operation in hazardous zones, reducing ignition risk and equipment failure. Business Impact This directly translates to higher uptime, lower maintenance costs, and better compliance with ATEX/IECEx-style standards in mining, chemical, and oil and gas sites. Application This is ideal for open-pit and underground mining conveyors, crushers, and other continuous-duty drives that demand rugged protection and long service life. Feature Cast-iron frame, 225 frame size, and 398 kg net weight deliver exceptional rigidity and vibration damping, enabling precise alignment and reduced bearing wear. Business Impact Reduced downtime, easier installation, and extended motor life when mounted on heavy-duty equipment in harsh environments. Application Suitable for gearboxes, couplings, and drive trains where robust mounting is essential. Feature 12-pole configuration and IMB5 IM3001 class bearings enhance torque stability and thermal capacity, supporting reliable continuous operation. Business Impact Improves process stability and motor cooling under full-load conditions, lowering maintenance frequency and energy waste. Application Mine conveyors, milling circuits, and other single-speed drives requiring solid torque control. Feature Ambient ratings of 40 °C and altitude up to 1000 m ensure reliable performance in outdoor and elevated installations. Business Impact Expands deployment options in open pits and high-altitude workplaces with consistent efficiency. Application Remote sites and surface operations where ambient conditions vary. Feature Insulation Class IC411 and Exdb protection deliver strong electrical robustness against moisture and heat. Business Impact Minimizes insulation breakdown risks, enabling safer operation in wet or dusty environments. Application crucial for long-term electrical integrity in mining plants. Feature Duty Type S1 confirms continuous operation capability, aligning with uninterrupted process requirements. Business Impact Supports steady production, predictable maintenance planning, and improved overall equipment effectiveness. Application Continuous-process motors in mills, crushers, and material handling systems.

FAQs
Install using the 225 frame with a top terminator box, compatible with standard couplings and mounts. Ensure Exdb enclosure and IP66 protection are preserved during mounting, and follow proper fastening torques. Align the shaft precisely to minimize vibration, and integrate with compatible VFDs or drives while maintaining safe clearances for explosive atmospheres.
Exdb is flameproof protection suitable for hazardous areas, while IP66 seals protect against dust and powerful water jets. IC411 insulation indicates a robust insulation system designed for demanding temperatures and moisture. Together, they ensure safer operation, reduced ignition risk, and reliable electrical integrity in mining and chemical plants.
Yes. The Exdb explosion protection and IP66 enclosure are specifically designed for hazardous-area use, supporting safe operation in mining environments. Combined with a cast-iron frame, 12-pole configuration, and robust bearings, it provides the reliability needed for continuous, demanding mining and processing applications.
Expect diligence on bearing checks (6313/C3 and 6312/C3 variants) and periodic inspection of the top terminator box. The IMB5 IM3001 class and cast-iron frame contribute to long life with low vibration. Maintain clean cooling paths, monitor for heat under load, and perform routine inspections aligned with continuous-duty (S1) operation.
The motor’s rugged Exdb/IP66 protection, high-torque 12-pole design, and continuous-duty capability reduce unplanned downtime and maintenance intervals. While upfront costs are higher, the improved uptime, safety compliance, and extended service life typically translate to lower total cost of ownership and faster payback in demanding mining environments.
