FAQs
This motor uses IMB3/IM1001 mounting, cast-iron frame size 250, and a top terminator box in a 884x626x430 mm envelope. Its D connection configuration simplifies wiring for 500 V supply. For field installations, ensure compatible mounting pads, proper alignment with driven equipment, and adequate space for heat dissipation and service access. With these requirements, commissioning is straightforward and repeatable.
Exdb protection ensures ignition protection in explosive atmospheres, critical in underground coal and mineral-processing sites. The ABB 3GJM251210-AEL incorporates Exdb along with IP66 enclosure to guard against dust, moisture, and gas hazards. This combination enables safe operation in hazardous zones, supports regulatory compliance, and reduces the risk of equipment-driven incidents in mining environments.
At 50 Hz, the IE3 categorization yields full-load efficiency near 94.3% (100% load) with 75% and 50% load values also listed (93.7% and 93.6%, respectively). Higher efficiency translates to lower energy costs and cooler operation, reducing cooling requirements and extending bearing life. Over a mining plant’s life, these savings can substantially lower total cost of ownership, especially in high-duty cycles.
Durability is driven by a cast-iron frame (Size 250), IP66 enclosure, Exdb flame protection, and insulation class ICLF, all designed for rugged mining environments. The motor employs robust bearings (6315M/C3 and 6313M/C3) and IMB3/IM1001 mounting for vibration resistance. Together, these features support reliable operation, lower maintenance intervals, and predictable uptime.
The motor uses a 500 V input with a D connection configuration, aligning with common industrial power networks. Benefits include simplified wiring, reduced risk of misconnection, and faster commissioning. Its compact footprint (Frame 250) and top-entry terminator box streamline on-site installation, while compatibility with IMB3/IM1001 mounting accelerates OEM integration and service routines.
