ABB 7BEM3157T General Purpose Motor - OPSB IE3
Part Number: 7BEM3157T
Quick Summary
ABB 7BEM3157T General Purpose Motor powers general-purpose drives in conveyors and pumps. Engineers often confront downtime and energy waste from undersized motors, and this model blends reliability with efficient operation. CSA, UR, and RoHS listings support safe, regulatory-compliant use, while IE3 efficiency and NEMA B design help reduce operating costs. Ideal for industrial automation, it complements standard 3-phase drives, and the OPSB enclosure simplifies installation and service in open plant environments. Operating at 230/460 V, 60 Hz with a 145T frame and a 1.15 service factor, it supports flexible integration across a range of equipment. The motor’s robust bearings and regreasable lubrication minimize maintenance downtime and extend service life.
