Overview

The Techtop XR3-CI-TF-145TC-2-B-D-2 is a 2 HP (1.5 kW) three-phase cast iron TEFC (Totally Enclosed Fan Cooled) motor designed for industrial applications requiring high efficiency and reliability. This motor, part number T145T2U2B, features a 145TC frame size with a 2-pole configuration delivering 2860 RPM at 50Hz. It supports dual voltage operation at 190/380V (50Hz) and 230/460V (60Hz), making it versatile for global installations. Key electrical specifications include a rated current of 6.4/3.2 Amps (high/low voltage), a service factor of 1.0, and a nominal efficiency of 84.2% (IE4 - NEMA Premium). The motor is tropicalized for harsh environments, with an IP55 rating for dust and water ingress protection. Insulation class H ensures thermal durability, while the 7024 graphite grey coating provides corrosion resistance. Certified by UL, CSA, and DOE, this motor meets stringent safety and efficiency standards. Mechanical robustness is ensured with 6205ZZ sealed ball bearings on both the drive end (DE) and non-drive end (NDE) sides, supporting a rated altitude of 1000 meters. The motor includes a removable cable entry (1.25 inches) and shaft grounding for electrical safety. With a locked rotor torque of 135% of full load and a breakdown torque of 211%, it handles transient loads effectively. The motor’s tropicalization and Class 1, Division 2, Groups A-D hazardous location certification make it suitable for chemical, oil & gas, and manufacturing environments. Applications include pumps, fans, compressors, conveyors, and machine tools where consistent performance and energy efficiency are critical. The dual-voltage wiring diagram (9-lead, 3-phase) simplifies installation across different power systems. With a weight of approximately 53 lbs and a temperature rise of 78.6°C at full load, this motor balances power density and thermal management. Backed by Techtop Industries’ technical support and compliance with global standards, the XR3-CI-TF-145TC-2-B-D-2 delivers dependable operation in continuous-duty applications.
