Exdb explosion protection provides enhanced safety for hazardous environments, reducing risk and enabling compliant operation in mining facilities. This translates to lower insurance costs, safer maintenance routines, and uninterrupted production along conveyors, pumps, and hoists. IP66 ingress protection guards against dust and water exposure, increasing uptime in harsh outdoor and underground applications while reducing maintenance intervals. IC411 insulation supports continuous operation at high ambient temperatures and in challenging atmospheres, improving reliability in 40°C conditions and at up to 1000 m altitude, where cooling can be a concern. IE2 efficiency delivers meaningful energy savings across full and partial loads, lowering operating costs without sacrificing performance. The 315 cast-iron frame and 2-pole design offer rugged mechanical robustness and high bearing life (6316/C3), ensuring durable service in demanding mining drives with top-entry terminator box for simpler installation. IMB5 IM3001 alignment and mounting compatibility simplify retrofits and new builds alike, while the Exd/Exdb protection supports compliant commissioning. Overall, this motor balances safety, efficiency, and durable construction for long-term ROI in mining and heavy industry.

FAQs
Yes. The 3GJM311230-BEG uses a 315 frame with a cast-iron enclosure and a top-entry terminator box, aligning with common IEC/industrial mounting patterns. Its IMB5 IM3001 class supports reliable mounting in new builds or retrofits, while the bearing arrangement (6316/C3) offers durable alignment for continuous duty environments.
The motor adheres to IE2 efficiency. Full load efficiency is 95.4%, with partial-load efficiencies of 95.2% at 75% load and 94.2% at 50% load. This performance supports energy savings across conveyors, pumps, and fans, reducing operating costs in mining and processing applications without compromising output.
Ideal for hazardous-area drives, the Exdb protection combined with IP66 ingress protection makes it suitable for underground conveyors, ore processing pumps, and hoists. The 315 frame, top-entry box, and robust cast-iron construction withstands tough ambient conditions up to 40°C and altitudes up to 1000 m, delivering dependable performance in demanding mining environments.
Key certifications include Exdb explosion protection, IP66 ingress protection, IC411 insulation, and IE2 efficiency. It is designed for hazardous areas in mining, with a durable cast-iron frame and a WEEE category classification for large equipment, ensuring regulatory compliance and waste management considerations across installations.
Top-entry terminator box, IMB5 IM3001 mounting, and a robust 6316/C3 bearing arrangement simplify installation and alignment. The rugged cast-iron frame reduces maintenance cycles, while IE2 efficiency lowers energy costs. These features collectively shorten downtime, extend service intervals, and deliver favorable total cost of ownership in continuous mining operations.
