Feature Exdb flameproof protection is integrated into the Exd design, enabling safe operation in hazardous zones found in mining and processing plants. This directly reduces ignition risk and compliance overhead while simplifying installation because protective barriers are built in. Applications include conveyors, crushers, and pumping stations in underground mines where safety-critical performance is non-negotiable. Feature IE2 efficiency with IC411 insulation delivers high efficiency under S1 duty. This translates into lower energy costs and cooler motor operation across full-load and part-load conditions, improving plant-wide energy management. The combination is ideal for continuous mining drives and other heavy-duty operations where uptime and energy efficiency are priorities. Feature IP66 enclosure and Cast Iron Frame 250 ensure durability in dusty, wet, and extreme environments. The robust housing reduces maintenance needs and extends service life in outdoor or demanding installations. Fitment with top termination and IMB3 IM1001 mounting makes it straightforward to install on conveyors and mills. Feature Two-pole design with Exd protection and bidirectional rotation offers high starting torque and flexible installation. The IM class IMB3 IM1001 and the top-placed terminal box simplify maintenance, while the 524 kg net weight (534 kg gross) signals the ruggedness of a mining-grade motor designed for long-term operation. Feature Certifications and build quality support compliance and lifecycle value. With country of origin Finland and customs tariff 85015381, procurement teams benefit from traceability and standardized logistics for scale deployment in mining sites.

FAQs
Plan for Exdb compliance with local explosion protection standards and ensure the IP66 enclosure remains intact in dusty or wet environments. Use the top-terminal box configuration for easy access, verify IMB3 IM1001 mounting compatibility, and maintain clearances for cooling at ambient temperatures up to 40 °C and altitude up to 1000 m.
IE2 indicates standard efficiency with Full Load around 94.4% and Partial Load around 94.5% at 75% load, dropping to roughly 93.9% at 50% load. Coupled with IC411 insulation, this supports stable temperatures and energy savings during long, continuous runs typical of mining drives and conveyors.
Yes, the 2-pole design delivers strong starting torque suitable for conveyors and heavy-load starts. For particularly demanding starts, consider a soft-start or drive system compatible with hazardous-area installations, ensuring motor protection and flameproof compliance are maintained.
Key certifications include Exdb flameproof protection, IP66 ingress protection, IE2 energy efficiency, and IC411 insulation. Additional conformance comes from its IMB3 IM1001 mounting class and robust cast-iron frame, all of which support safe operation in mining and similar industries.
The rugged cast-iron frame, top-terminated box, and reliable bearings (6315M/C3 and 6313M/C3) minimize downtime and maintenance intervals. IE2 efficiency lowers energy costs over the motor’s life, while Exd/IP66 compliance reduces regulatory risk, contributing to a favorable return on investment in continuous mining operations.
