Overview

The Techtop GR3-AL-TF-145JM-2-B-D-2 is a 2 HP, 145JM frame, 2-pole (3600 RPM) TEFC industrial motor designed for reliable performance in demanding applications. Rated for dual-voltage operation at 230/460V and 60/50 Hz, this NEMA Premium IE3 motor delivers 85% nominal efficiency with a service factor of 1.25, ensuring optimal energy savings and extended operational life. The motor operates at a rated current of 5.2/2.6 Amps (high/low voltage) and features a temperature rise of 47.4°C at full load, meeting NEMA Design B-E standards for consistent torque and current characteristics. Built with a robust TEFC (Totally Enclosed Fan-Cooled) enclosure rated IP55, the GR3-AL-TF-145JM-2-B-D-2 is protected against dust ingress and water jets, making it suitable for harsh industrial environments. The motor’s graphite grey 7024 coating provides additional corrosion resistance, while its tropicalized design ensures reliable operation in elevated temperature conditions. Certified to UL, CSA, and DOE standards, this motor complies with Class 1, Division 2, Groups A-D hazardous location requirements, offering versatility for use in potentially explosive atmospheres. Mechanically, the motor is equipped with 6205ZZ sealed ball bearings on both the drive end (DE) and non-drive end (NDE) sides, ensuring low friction and long service life. The shaft grounding feature is not included, but the motor’s design includes a removable 1.25-inch cable entry for flexible wiring options. With a rated altitude of 1000 meters and a noise level compliant with NEMA standards, this motor is optimized for continuous duty in industrial machinery, pumps, fans, and material handling systems. Key electrical data includes a locked rotor torque of 283% of full load, a breakdown torque of 362%, and a pull-up torque of 169%, providing strong starting and acceleration capabilities. The motor’s insulation class F and tropicalization ensure reliable operation in ambient temperatures up to 40°C. Weighing approximately 48.4 lbs, the GR3-AL-TF-145JM-2-B-D-2 is a compact yet powerful solution for applications requiring high efficiency, durability, and compliance with stringent industry standards.
