Feature → Business Impact → Application: Exdb flameproof protection provides enhanced safety in potentially explosive atmospheres, reducing risk of ignition and ensuring regulatory compliance in underground mining or chemical processing. This protection translates to lower total cost of ownership through fewer unplanned shutdowns and safer maintenance operations, ideal for long-wall conveyors and ore handling. Feature → IEC IE2 efficiency class delivers improved energy performance and reduced running costs over legacy motors, which is critical for continuous-duty processes in mineral processing plants and bulk material handling. Feature → IP66 enclosure and rugged cast iron frame withstand dust, water ingress, and harsh environments, improving uptime in outdoor installations and dusty underground sites. Feature → 8-pole, 3JM2__M3JM_IE2 Group I Flameproof Exd design with IMB5 IM3001 mounting ensures reliable slow-speed torque and stable operation for hoists, crushers, and winches. Feature → Top terminator box location simplifies electrical connections during installation and service, reducing downtime and enabling safer field maintenance. Feature → Bearing combination 6315/C3 and 6313/C3 with IM class IMB5 IM3001 supports long bearing life and smoother operation under high-load mining tasks, such as belt conveyors and fans. Feature → Altitude up to 1000 m and ambient temperature 40 °C capability ensures reliable performance at remote, elevated mining sites, including ore processing facilities and mobile equipment environments. Feature → Compliance with WEEE and international classifications ensures responsible end-of-life handling and alignment with corporate sustainability goals across global operations.

FAQs

This model uses a top termination box and IMB5 mounting, with a 250 frame and bearings 6315/C3 and 6313/C3. Plan for a rugged, cast-iron enclosure, ensure IP66 sealing, and verify ambient temperature and altitude (40 °C, up to 1000 m). Confirm Exdb flameproof protection and Exd classification for safe operation in hazardous zones.
Key electrical specs include IE2 efficiency, 8-pole configuration, voltage code S, and S1 duty. It is a 3-phase squirrel cage motor with Exdb protection and IP66 enclosure, designed for continuous operation in demanding environments. Use with compatible drives and wiring practices to maintain performance and safety margins.
Yes. The motor is designed with Exdb flameproof protection and Exd flameproof characteristics suitable for group I mining applications. Its rugged cast iron frame and IP66 enclosure help ensure safe operation in explosive atmospheres and dusty, damp underground locations.
Expect Exdb explosion protection, IP66 enclosure rating, IC411 insulation class, and IE2 efficiency. The unit is built to withstand harsh industrial environments, with WEEE categorization for waste handling and Finland-origin manufacturing. Warranties and local regulatory conformity should be verified with the supplier.
The motor’s cast iron frame, heavy-duty bearings (6315/C3 and 6313/C3), and IMB5 IM3001 mounting support long service life and reduced maintenance intervals. IE2 efficiency lowers energy costs, and Exdb/IP66 protection minimizes downtime due to environmental exposure. Overall, this translates to lower lifecycle costs and greater asset availability in conveyors, crushers, and shaft equipment.
