Overview

Techtop Motors GR3-CI-TF-326TS-2-BR-F-50 is a 50 HP, 3-phase, 575V, 60Hz, 2-pole (3600 RPM) Totally Enclosed Fan-Cooled (TEFC) cast iron motor designed for industrial applications requiring high efficiency and reliability. This NEMA Premium IE3 motor delivers 93% nominal efficiency, ensuring energy savings and compliance with DOE regulations. With a service factor of 1.25, it handles temporary overloads up to 25% above rated load without derating. The motor features a 326TS frame size, IP55 rating for dust and water ingress protection, and Class F insulation with a 63.3°C temperature rise at full load. Certified to UL, CSA, and DOE standards, it is suitable for hazardous locations (Class 1, Div 2, Groups A-D) and operates reliably in ambient temperatures up to 40°C at altitudes up to 1000 meters. The motor includes a 1.25-inch removable cable entry, dual drilled feet for mounting flexibility, and 6312 C3 bearings on both drive-end (DE) and non-drive-end (NDE) sides for extended bearing life. With a locked rotor torque of 374 ft-lb and a breakdown torque of 304% of full load, it provides robust starting and running performance. The motor's tropicalized construction resists moisture and corrosion, making it ideal for harsh industrial environments. Applications include pumps, fans, compressors, conveyors, and machine tools where high efficiency, durability, and compliance with energy regulations are critical.
