Feature → Business Impact → Application: The 326T frame and 50 HP rating deliver ample torque for air handling units and packaged HVAC equipment, reducing sizing risk and enabling reliable start‑up in demanding environments. This translates to measurable efficiency gains and energy cost reduction in continuous‑duty fans and blowers. The IE3 premium efficiency rating, along with a 87% power factor, lowers operating current and heat generation, improving motor life and reducing cooling load in control rooms. The OPSB enclosure provides superior protection against dust and moisture, enabling longer service intervals in dusty plants or humid environments and simplifying compliance with electrical standards. Direct On Line starting supports fast commissioning and minimized maintenance, while greasable bearings offer extended life in high‑vibration HVAC setups. Compatibility with 230/460 V and 60 Hz ensures seamless integration with existing drives and switchgear, avoiding costly reconfiguration. The 2.13 in shaft diameter and 1775 r/min nominal speed support standard coupling and belt drive designs, reducing installation costs and downtime. Overall, this motor aligns with lean maintenance practices and provides predictable performance for reliable facility operation.
