Feature → Business Impact → ApplicationTEFC enclosure and 256T frame provide robust protection for windings in dusty or humid environments, reducing maintenance and extending motor life. This translates to longer uptime for conveyors, pumps, and fans in packaging lines and process plants. The 256T frame also supports straightforward mounting and swap-in replacement in existing installations.Premium Efficiency (93%) delivers meaningful energy savings over the motor’s lifecycle, lowering operating costs in continuous-duty applications such as conveyors, pumps, and blowers, while meeting corporate sustainability goals. Ideal for facilities targeting energy-per-HP improvements and utility rebates.3-phase, 60 Hz operation with 4-pole design delivers predictable, steady speed (1770 r/min) and simple control for standard industrial drives, minimizing torque ripple and improving process stability. This is advantageous for mixers, agitators, and centrifuge systems.Direct On Line starting keeps automation simple with minimal components, reducing upfront costs and installation time; where service power quality permits, a soft-start option can be considered to manage inrush for sensitive equipment.Stocked at multiple warehouses with 0 day lead time, this motor enables rapid procurement and project scheduling, reducing downtime during maintenance or expansion projects and supporting peak demand planning.Foot-mounted, horizontal mounting (F2) and the 1.63 in shaft diameter simplify installation and retrofits in existing belt conveyors and material-handling setups, while 256T size ensures robust coupling and alignment flexibility.
