Overview

Techtop VHS-CI-447TP-4-E-400 is a high-efficiency, 400 HP, 3-phase induction motor designed for industrial applications requiring reliable, high-torque performance. Built to NEMA Premium IE3 efficiency standards, this motor delivers 96.2% nominal efficiency at 460V, 60Hz, ensuring energy savings and compliance with DOE regulations. The 447TP frame size provides robust mechanical integrity, while the WP (weather-protected) enclosure offers IP55 protection against dust and water ingress, suitable for harsh industrial environments. Key electrical specifications include a rated current of 441.5 Amps, a service factor of 1.15, and a full-load torque of 1183 ft-lb at 1786 RPM. The motor features a Class F insulation system with tropicalization for enhanced durability in humid or corrosive conditions. Certified to UL, CSA, and DOE standards, it meets stringent safety and performance requirements. The motor’s 125% overload capability (1781 Amps) and breakdown torque of 356% of full load ensure reliable operation under demanding conditions. Mechanical robustness is ensured with double-shielded 6306ZZ bearings on both drive-end (DE) and non-drive-end (NDE) sides, providing long service life. The motor’s graphite grey coating (7024) enhances corrosion resistance, while the removable feet design simplifies installation and maintenance. With a rated ambient temperature of 40°C and a maximum altitude rating of 1000 meters, this motor is engineered for continuous duty in industrial settings such as pumps, compressors, fans, and material handling systems. The VHS-CI-447TP-4-E-400 is part of Techtop’s VHS series, known for its high reliability and efficiency in variable frequency drive (VFD) applications. Its NEMA Design B characteristics ensure stable performance across a wide range of loads, from 50% to 125% of full load. The motor’s compact 447TP frame size balances power output and physical footprint, making it ideal for retrofits or new installations where space is a consideration.
