FAQs
The 3GJM253220-BDG uses a 250 frame with a cast iron construction and IMB5 IM3001 mounting class, designed for standard foot or flange mounting in industrial drives. Verify foundation size and alignment, ensure top terminator box access for wiring, and confirm filter-free clearance for service and cooling. This minimizes retrofit risk and speeds installation.
IE2 efficiency for, example, Full Load (100%) is 92.9%, with Partial Load (75%) around 93.3% and Partial Load (50%) near 93.1%, indicating strong energy performance across load profiles. This translates to steady energy savings in conveyors and processing lines, reducing operating costs over the motor’s life while maintaining reliable torque delivery.
Yes. The motor features Exdb explosion protection and IP66 ingress protection, making it appropriate for hazardous mining zones and dusty, washdown environments. Combined with IC411 insulation and IE2 efficiency, it supports safe operation, regulatory compliance, and long service intervals in demanding underground and surface applications.
Plan for a solid foundation compatible with a 250 frame, top terminator box, and a 521 kg net/531 kg gross weight profile. Check bearing life with 6315/C3 and 6313/C3, ensure proper cooling and ventilation, and confirm the integral alignment with IMB5 IM3001 mounting. These steps reduce vibration, simplify maintenance, and ensure reliable startup.
Key standards include IP66 protection, Exdb hazardous-area protection, IC411 insulation, and IE2 efficiency under IEC norms. The motor is designed for S1 duty with a 40 °C ambient limit and 1000 m altitude, supporting regulatory compliance in mining and heavy industry while delivering predictable, energy-efficient operation.
