Flameproof Exdb protection and IP66 enclosure combine to prevent ignition in hazardous mining environments, reducing risk of explosions and simplifying regulatory compliance for asset owners. This feature translates to lower downtime and safer operations, especially where dust and water ingress are ongoing concerns, such as underground galleries and surface processing lines. The motor’s IE3 premium efficiency delivers tangible energy savings across continuous operations at 50 Hz, lowering total cost of ownership and supporting sustainability reporting for mining sites. The 500 V, 4-pole, 75 kW configuration provides robust torque with a smooth, reliable start-up for heavy-load drives, while the D connection supports straightforward electrical integration with standard 3-phase systems. Cast Iron frame 280 and bearings 6316/C3 ensure rotordynamic stability, enhancing longevity in rugged environments and reducing maintenance intervals. IMB3/IM1001 mounting compatibility simplifies retrofits and new installations, and the IC411 insulation plus 40 °C ambient rating up to 1000 m enable operation in hot, elevated sites. Altogether, the design supports predictable maintenance planning and fleet standardization for mining operations.

FAQs
Follow IMB3/IM1001 mounting guidelines using the D-End top terminator box and aligned shaft positioning. Wire the motor to a 500 V, 50 Hz three-phase supply with the D configuration, verify bearing preload and torque settings per the ABB installation sheet, and secure the terminal box to maintain IP66 integrity. Use shielded cables and proper grommets to prevent ingress and ensure serviceability.
At 50 Hz full load, the motor delivers 75 kW with IE3 efficiency. IE Class data indicate Full Load (100%) efficiency around 95.0%, with 75% and 50% loads at 95.2% and 94.8% respectively. The 4-pole design provides a stable torque curve suitable for continuous S1 duty in mining drives, supporting consistent performance across load variations.
Yes. The Exdb flameproof protection and IP66 enclosure are specifically intended for explosive atmospheres common in underground mining. With IC411 insulation and a 40 °C ambient rating up to 1000 m, it maintains safe, reliable operation under hot, elevated conditions. The IMB3/IM1001 mounting supports typical mining drive assemblies, simplifying integration in confined spaces.
The motor features Exdb flameproof protection and IP66 sealing, aligning with IECEx/ATEX expectations for mining equipment. It also carries IE3 premium efficiency, IC411 insulation, and a flameproof Exd protection profile. These certifications support regulatory compliance, safer operation, and consistent performance across mining sites with demanding safety requirements.
The premium IE3 efficiency reduces energy consumption, delivering measurable ROI over the motor’s life. Robust bearings (6316/C3) and a cast iron frame enhance uptime and lower maintenance intervals. Exd flame protection and IP66 enclosures extend service intervals in harsh environments, while high-altitude and hot-site ratings enable predictable maintenance planning for mining fleets and lifecycle cost savings.
