Feature → Business Impact → Application: The 25 HP output in a 284T frame provides ample torque with a compact footprint, reducing retrofit complexity in existing plant layouts and enabling straightforward replacement in Baldor-Reliance installations. This translates to lower downtime during maintenance and faster project turnaround for upgrading crushers and mills. Feature → Premium Efficiency (NEMA Premium) → Energy savings and lower operating costs, improving overall plant profitability in continuous-duty processes such as crushing and material handling. Feature → TEFC enclosure → Harsh-environment reliability and protection against dust and moisture, enabling operation in dusty mining sites and long-term uptime for conveyors and feeders. Feature → 60 Hz, 230/460 V, 3-phase supply → Broad compatibility with standard plant electrical systems, simplifying procurement and reducing on-site wiring complexity. Feature → 1.25 Service Factor → Improved torque reserve to handle brief overloads without tripping, beneficial for startup transients in crushers and grinding circuits. Feature → Foot-mounted, horizontal mounting (F1) → Easy installation with conventional bases, reducing commissioning time and enabling reuse in retrofit projects. Industry context shows that these design choices support reduced total cost of ownership and better Return on Investment for mineral processing and aggregate operations.
