Flameproof Exdb protection provides a robust safety envelope for hazardous mining environments, reducing ignition risk during startup and operation. Business impact includes lower incident-related downtime and easier regulatory audits, while the application spans underground and surface mining equipment where explosive atmospheres may be present. IE3 premium efficiency drives meaningful energy savings at both full and partial loads, which translates into lower operating costs and extended asset life on conveyors and crushers. IP66 enclosure and ICFL insulation ensure the motor resists dust, moisture, and temperature swings, enabling stable performance in harsh sites and reducing maintenance interventions. The 2-pole, 45 kW design at 500 V with 50 Hz input delivers strong torque characteristics for heavy-duty drives without sacrificing efficiency, easing integration with standard mine electrical infrastructure. Compatibility with D connection, IMB3/IM1001 mounting, and the top-termination box simplifies site wiring, speeding commissioning while maintaining safe clearances. Reversible rotation on both sides offers installation flexibility in tight underground layouts, minimizing the need for rework. Altitude capability up to 1000 m and ambient temperatures up to 40 °C support consistent uptime in variable mining environments. Bearing configurations 6313M/C3 and 6312M/C3 in a cast-iron frame 225 ensure rugged durability and predictable maintenance windows, reducing total cost of ownership over the motor’s life.

FAQs
Begin by confirming duty cycle (S1) and ensuring the environment matches IP66, Exdb, cabinet cooling, and 40 °C ambient ratings. Use the D connection configuration, mount with IMB3/IM1001, and follow top-termination box accessibility requirements for safe wiring. Align with frame size 225 and ensure correct sealing and cable glands to minimize commissioning risk and maximize uptime in harsh mining rooms.
Exdb indicates the enclosure provides flameproof protection to prevent ignition of surrounding explosive atmospheres. This supports safer operation in underground mines and aligns with regulatory requirements for equipment exposed to combustible dust or gas. Installations must use certified procedures and components, and periodic inspections should be documented to maintain compliance and insurance coverage.
The 45 kW output with 500 V, 50 Hz aligns with common mine electrical infrastructure, delivering strong torque for conveyors and crushers while staying within typical circuit limits. IE3 efficiency reduces losses across full and partial load conditions, lowering energy bills and heat generation. The 2-pole design also supports predictable speeds that match standard mine drive systems for robust performance.
Plan for bearings using 6313M/C3 and 6312M/C3, a cast-iron frame for durability, and IMB3/IM1001 mounting to simplify diagnostics. With ICFL insulation and IP66 protection, extended service intervals are feasible, decreasing downtime. Exdb flameproof construction reduces ignition risk, aiding warranty and insurance considerations. A preventive plan at 1000 m altitude and 40 °C ambient helps maintain uptime and control spare parts spend.
Yes. The motor is designed for IMB3/IM1001 mounting and is compatible with standard ABB drive systems, simplifying integration with existing mining drives. Its 225 frame, 2-pole configuration and D connection streamline wiring, while the top termination box location reduces installation complexity. Reversible rotation on both sides adds installation flexibility in constrained spaces.
