Overview

The TechTop XR3-AL-TF-145T-4-B-D-2 is a 2 HP, 4-pole (1800 RPM) three-phase induction motor designed for industrial applications requiring high efficiency and reliability. This motor features a 145T frame size, Totally Enclosed Fan-Cooled (TEFC) enclosure, and dual-voltage operation at 230/460V (60Hz) or 190/380V (50Hz). With a nominal efficiency of 85.3% (IE4 - Super Premium), it meets DOE and NEMA Premium efficiency standards, reducing energy consumption and operational costs. Key electrical specifications include a rated current of 6.52A (230V) / 3.26A (460V), service factor of 1.15, and a locked rotor current of 21 times rated current. The motor is designed for continuous duty (Cont.) with a temperature rise of 31°C at full load. It features Class H insulation, tropicalization for harsh environments, and shaft grounding to protect against bearing currents. The IP55 rating ensures protection against dust and water jets. Mechanically, the XR3-AL-TF-145T-4-B-D-2 includes 6205ZZ sealed ball bearings on both the drive end (DE) and non-drive end (NDE) sides, with a removable cable entry of 1.25 inches. The motor weighs approximately 44.02 lbs and is coated in graphite grey (7024) for corrosion resistance. Certified to UL, CSA, and DOE standards, it is suitable for hazardous locations (Class 1, Div 2, Groups A-D) and operates reliably up to 1000 meters altitude. Ideal for pumps, fans, compressors, and material handling equipment, this motor delivers consistent performance with low maintenance requirements. Its dual-voltage wiring (9-lead configuration) allows flexible installation in both 230V and 460V systems, while the TEFC enclosure ensures durability in dusty or wet environments. The motor's high efficiency and robust construction make it a cost-effective choice for industrial OEMs and end-users seeking long-term reliability.
