Feature → Business Impact → Application: The 350 HP, 460 V, 1785 r/min, 3-phase, 60 Hz specification delivers high torque and favorable compatibility with common industrial power systems, enabling reliable performance in crushers and conveyors. This is paired with a TEFC enclosure and a robust 449T frame, which reduces dust ingress and moisture exposure, extending service life in harsh processing environments. The motor achieves Premium Efficiency (96.20%) to lower energy consumption and operating costs during continuous-duty cycles typical in mining and material handling facilities. A service factor of 1.15 provides tolerance for short overloads during peak loading or startup surges, supporting smoother operation of crushers and grinding mills. Ball bearings (6318 | NDE) and a standard drive-end flange contribute to reduced maintenance intervals and longer bearing life, improving total cost of ownership. Direct-on-line starting simplifies electrical installation and minimizes soft-start equipment needs, while stock availability across US and China warehouses accelerates project timelines. With a foot-mounted, horizontal mounting orientation and the 449T frame size, installation is straightforward in retrofit or new-built plants, aligning with existing NEMA design practices for reliable, scalable operation.
