125 HP, 460 V, and 1775 rpm meet the requirements of standard industrial drives while the 405TC frame provides a familiar mounting footprint. This combination delivers consistent mechanical power for mid-duty loads, enabling reliable operation of pumps, fans, and conveyors without costly redesigns. In practice, users experience smoother starts and predictable load profiles, improving line efficiency and uptime. An OPSB enclosure protects the windings in open environments, reducing maintenance cycles in production lines with ambient contaminants. With C-Face drive end flange and a foot-mounted base, installation aligns with common in-house practices, minimizing mounting adapters and alignment time. Premium Efficiency at 95.40% and a power factor around 0.86 translate into tangible energy savings, especially in high-duty cycles. The 1.15 service factor provides a comfortable margin for peak loads, while insulation class F offers better heat resistance in moderate ambient temperatures. Starting of Motor is Wye Start - Delta Run, which helps reduce inrush during startup and extend drive life. Durability is reinforced by bearings of 6316 and a 2.88 in shaft, while the steel frame and OPSB enclosure are built to endure the vibrations and temperatures typical of continuous operation in manufacturing settings. With a synchronous speed of 1800 r/min and a rated speed of 1775 r/min, the motor delivers a smooth, near-synchronous performance ideal for belt-drive systems and conveyors. This motor also benefits from standard stocking across multiple warehouses, enabling faster project kickoff and reduced lead times for upgrades and new installations.
