Overview

The Techtop Motors CB1-AL-TF-145TC-4-B-C-3 is a 3 HP single-phase industrial motor engineered for reliable performance in demanding applications. Built with a 145TC frame size and NEMA Design L, this motor delivers 1730 RPM at full load with a service factor of 1.15, ensuring consistent operation under variable loads. Rated for dual voltage operation (115V or 230V at 60Hz), it supports flexible installation in facilities with single-phase power distribution. The motor achieves an IE3 NEMA Premium efficiency rating of 81% with a power factor of 0.9 cosθ, reducing energy consumption and operational costs compared to standard motors. Its tropicalization ensures reliable operation in high-humidity conditions. The motor includes a start capacitor (600µF / 165V) and run capacitor (100µF / 250V) for optimized starting and running performance. With a full load torque of 5.29 Ft-Lb and a temperature rise of 34.7°C at full load, it maintains stable thermal performance even under sustained operation. Mechanical robustness is ensured with 6205-ZZ bearings on both the drive end (DE) and non-drive end (NDE), providing long service life. The motor’s graphite gray coating (7024) enhances corrosion resistance, while removable feet allow versatile mounting options. Rated for ambient temperatures up to 40°C and altitudes up to 1000 meters, it is suitable for a wide range of industrial applications, including pumps, fans, compressors, and general machinery where single-phase power is utilized. The 1/2 NPT cable entry simplifies wiring, and the motor’s compact design (51.3 kg) facilitates easy integration into existing systems. Key electrical specifications include rated currents of 26.2A at 115V and 14.5–13.1A at 208–230V, with a locked rotor current of 30.45A. The insulation class F and tropicalization further contribute to its durability and reliability in industrial settings.
