Overview

The Techtop SS3-TF-145TC-4-D-1.5 is a 1.5 HP, 4-pole (1800 RPM) stainless steel Totally Enclosed Fan-Cooled (TEFC) motor designed for industrial applications requiring high efficiency and durability. Built to NEMA Premium IE3 standards, this motor delivers 86.5% nominal efficiency at 60Hz and 230/460V dual-voltage operation, ensuring energy savings and compliance with DOE regulations. The 145TC frame size provides compatibility with standard mounting configurations, while the stainless steel construction offers superior corrosion resistance in harsh environments. Key electrical specifications include a rated current of 4.45A (230V) / 2.22A (460V), service factor of 1.25, and insulation class F for reliable operation up to 40°C ambient temperatures. The motor features a 9-lead dual-voltage wiring configuration for flexible installation, with a locked rotor torque of 318% of full load and breakdown torque of 396%. Bearings are pre-lubricated 6205 2RS (drive end) and 6204 2RS (non-drive end) for extended service life. Certified to UL, CSA, and DOE standards (File Nos. 323353, 224693, 096A), this motor is ideal for pumps, fans, compressors, and material handling systems where consistent performance and energy efficiency are critical. The TEFC enclosure protects against dust and water ingress (IP69K rating), while the unpainted stainless steel finish resists corrosion in washdown or outdoor applications. With a tropicalization rating and 1000m rated altitude, it meets the demands of diverse industrial settings. Mechanical data includes a full load torque of 4.46 ft-lb, temp rise of 49.1°C at full load, and a noise level compliant with NEMA standards. The motor’s 53.2 lb weight and compact 56 frame size simplify installation in tight spaces. For variable speed applications, the motor supports a CT VFD range, though no brake voltage is provided.
