Built to NEMA Premium IE3 standards, this motor delivers 85.5% nominal efficiency at 3500 RPM, ensuring energy savings and reduced operating costs. The 145TC frame size provides compatibility with standard mounting configurations, while the Totally Enclosed Fan-Cooled (TEFC) enclosure protects against dust and moisture ingress (IP55 rating), making it suitable for harsh environments. Key electrical specifications include dual-voltage operation at 230/460V (60Hz) or 230/460V (50Hz), with rated currents of 5.18A (230V) and 2.59A (460V). The motor features a service factor of 1.25, allowing temporary overloads up to 25% without damage. With a locked rotor torque of 294% of full load and a breakdown torque of 332%, this motor provides robust starting and running performance for demanding applications. The aluminum construction reduces weight by 31.57 lbs compared to cast iron alternatives, while the Class F insulation and tropicalization ensure durability in high-temperature and humid conditions. Certified to UL, CSA, and DOE standards, the GX3-AL-TF-145TC-2-B-D-2-BRK is ideal for pumps, fans, compressors, and material handling equipment. The 9-lead dual-voltage wiring configuration simplifies installation and compatibility with variable frequency drives (VFDs). Additional features include shaft grounding for bearing protection, removable feet for flexible mounting, and a brake voltage of 205V DC with 16 N·m brake torque for precise stopping in positioning applications. The motor meets Class 1, Division 2 hazardous location requirements, expanding its use in potentially explosive atmospheres.
