FAQs
Plan for a 3-phase, Y-connected configuration with 400 V supply and 50 Hz frequency. Use IMB5/IM3001 mounting, top terminator box, and ensure IP66 enclosure and Exdb protection. Verify ambient conditions up to 40 °C and altitude up to 1000 m. The frame size 280, bearing 6316/C3, and cast-iron construction support robust on-site installation and long service life.
Exdb protection enables safe operation in potentially explosive atmospheres, reducing ignition risk during starts and loads. This lowers the need for frequent retrofits and safety interlocks, simplifying maintenance planning and ensuring compliance with hazardous-area standards while maintaining continuous operation in conveyors and crushers.
Yes. The motor’s IP66 enclosure, Exdb protection, IE3 efficiency, and 37 kW rating are well-suited for underground conveyors and processing lines. Its 8-pole, 400 V, 50 Hz setup with robust IMB5/IM3001 mounting supports reliable, heavy-duty operation with predictable torque and reduced lifecycle costs.
Key standards include IE3 efficiency class, IP66 ingress protection, IC411 insulation, and Exdb explosion protection. The motor is designed for flameproof use in mining environments and features IMB5/IM3001 mounting for secure installation, with a North European origin and Finland production lineage noted in the specification.
The premium IE3 efficiency reduces energy costs across high-load cycles, while Exdb and IP66 protections minimize maintenance and downtime in hazardous zones. Cast-iron frame and durable bearings extend service life, enabling longer intervals between repairs and a favorable return on investment through lower operating expenses and higher uptime.
