FAQs
To install, ensure a secure foundation for the 785 kg net weight motor and proper mounting to a 280 frame. Use the top terminator box for wiring with correct conduit entries, keeping cable routes clear of moving parts. Verify ambient conditions (40 °C max) and altitude (up to 1000 m) before commissioning. Align shaft carefully and follow IEC practices for hazardous-area installations due to Exdb protection.
This is a 3-phase, 4-pole motor with IE2 efficiency. Full-load efficiency is 94.7%, with approximately 95% efficiency at 75% load and 94.5% at 50% load. It operates under S1 duty (continuous) for sustained operations, making it suitable for long-running conveyors, crushers, and processing lines in demanding environments.
Yes. The motor features Exdb flameproof protection and an IP66 enclosure, designed for hazardous atmospheres and dusty, humid mining sites. Its IC411 insulation class and robust cast-iron frame further support safe operation in harsh conditions, while meeting essential standards for explosion protection and electrical safety.
Key certifications include IP66 ingress protection, Exdb explosion protection, and IC411 insulation. The motor also supports IE2 efficiency and IMB3 IM1001 mounting class, with a 4-pole design suitable for safe, continuous operation in heavy industrial environments. All material choices and packaging align with heavy equipment compliance and WEEE category guidance.
The rugged, cast-iron 280 frame, top-entry box, and high-grade bearings (6316/C3) contribute to long service life and reduced maintenance intervals. Expect lower downtime due to protection ratings, improved energy efficiency, and predictable performance under S1 duty. Combined with reliable supply from Finland (FI), the unit supports lower total cost of ownership in mining and processing facilities.
