TEFC enclosure and 404T frame deliver rugged protection against dust, moisture, and heavy shaft loading, reducing wear and extending service life in harsh environments such as conveyors and crushers. This translates to lower maintenance costs and shorter downtime. Regreasable bearings (80BC03J30X) enable scheduled lubrication, cutting maintenance frequency and total cost of ownership while maintaining peak performance in pumps and compressors. A 60 Hz, 460 V, 3-phase design with 50 HP output, 89.5% efficiency, and 1.15 service factor provides reliable torque with energy savings for continuous-duty applications like fans, pumps, and material-handling equipment. The motor is designed to meet NEMA Design D and insulation Class F standards, delivering strong starting torque and thermal resilience for demanding startup demands in heavy-industry lines. Stocked at multiple warehouses with 0-day lead times supports rapid deployment on project timelines, reducing capital lock-in and accelerating ROI. With a foot-mounted 404T frame and a 2.88 in shaft, installation is straightforward, minimizing commissioning risk and ensuring compatibility with existing mechanical baselines. These features collectively reduce unplanned outages and improve plant-wide reliability for critical processes.
