Overview

The Techtop GR3-AL-TF-143JM-4-B-D-1 is a NEMA Premium IE3 1 HP, 4-pole (1800 RPM) three-phase induction motor designed for industrial applications requiring high efficiency and reliability. This TEFC (Totally Enclosed Fan-Cooled) motor operates at 230/460V, 60Hz (or 230/460V, 50Hz) with a service factor of 1.25, providing robust performance under varying load conditions. The motor features a 143JM frame size, dual-voltage wiring (9-lead configuration), and a graphite grey 7024 coating for corrosion resistance. With a nominal efficiency of 85.5% and a power factor of 0.74, it meets DOE and NEMA Premium efficiency standards, reducing energy costs by up to 15% compared to standard motors. Certified to UL, CSA, and DOE standards, this motor is suitable for hazardous locations (Class 1, Div 2, Groups A-D) and operates efficiently at altitudes up to 1000 meters. The motor includes 6205ZZ sealed bearings on both drive-end (DE) and non-drive-end (NDE) sides, ensuring long service life with minimal maintenance. Ideal for pumps, fans, compressors, and conveyor systems, the GR3-AL-TF-143JM-4-B-D-1 delivers consistent torque (3.05 ft-lb at full load) and a temperature rise of 36°C at full load, maintaining reliability in continuous duty applications. Its tropicalized design enhances durability in humid or corrosive environments, while the removable feet and 1.25-inch cable entry simplify installation and wiring.
