FAQs
This motor uses a D connection configuration with a 500 V supply at 50 Hz and 6 poles (Frame 355). It mounts on IMB5/IM3001 bases with a D-End top terminator box, suitable for ATEX/IECEx installations and rugged industrial layouts. Plan for space to accommodate the 1584 mm length, 968 mm height, and 700 mm width, plus a ballast of ~2215 kg gross for foundation design.
IE3 efficiency data shows Full Load around 95.8% at 50 Hz and 60 Hz, with similar partial-load performance (75% and 50%). This translates to meaningful energy savings in continuous-duty applications such as pumps and fans, reducing operating costs over the motor’s lifetime while maintaining required torque and starting profile.
Yes. The motor is Exdbeb protected, suitable for explosive atmospheres, and categorized for Gas Group IIB. This makes it appropriate for chemical, petrochemical, and refining environments where flameproof equipment is mandated to mitigate ignition risks.
Key dimensions include a 355 frame size with a 1584 mm depth, 968 mm height, and 700 mm width. It uses a Cast Iron frame with Bearings 6322/C3 and 6316/C3, and supports IMB5 IM3001 mounting. With a 2199 kg net weight and 2215 kg gross weight, ensure structural support and foundation are designed for heavy equipment and vibration control.
ROI benefits come from reduced energy consumption due to IE3 efficiency, lower maintenance from IP55 protection and robust bearings, and decreased downtime due to reliable Ex protection in hazardous zones. The combination of safer operation, longer service intervals, and compatibility with existing ABB drives reinforces long-term lifecycle value and predictable maintenance planning.
