FAQs
The motor uses a D (Delta) connection configuration suitable for 500 V line voltage. For IMB3 mounting, align the base to the IMB3/IM1001 footprint, position the top termination box for accessible wiring, and follow standard alignment and torque specs for the frame size 225. This approach ensures optimal torque delivery, reliable cooling, and straightforward electrical connection during commissioning.
At 50 Hz, the IE3-class motor delivers approximately 94.0% full-load efficiency, with about 93.8–94.2% at partial loads (50–75%). At 60 Hz, efficiency remains high, with ~93.6% full-load and about 92.0–93.2% at partial loads. These figures reflect the robust energy savings you gain under typical mining drive cycles and belt-conveying loads.
Yes. The 3GJM221210-AEK features Exdb explosion protection and an IP66 enclosure, providing the necessary protection in hazardous underground and surface mining environments. Its flameproof design and ICFL insulation with IC411 duty further support compliance with safety standards while maintaining reliable operation in tough conditions.
The motor provides a rugged cast-iron frame, bearings specified as 6313M/C3 and 6312M/C3, and a sealed enclosure that minimizes ingress. IP66 protection, top termination box, and IMB3/IM1001 mounting enable easier service access and reduced maintenance downtime, especially in dusty or humid mining sections and high-heat installations.
ROI is driven by premium IE3 efficiency, reducing energy costs across long-mining shift cycles, and by lowered downtime due to robust protection (Exdb, IP66) and durable components. Expect extended service life from a cast-iron frame and protected bearings, plus simpler installation and maintenance with IMB3 mounting, contributing to lower total cost of ownership in mining operations.
