TECO Totally Enclosed Fan-Cooled (TEFC) Motor (NEMA Standard)

As a premium offering for the North American market, TECO’s TEFC motor is fully engineered and manufactured to comply with NEMA MG-1/MG-13 standards, integrating high efficiency, durability, and environmental adaptability. Certified by UL, CSA, and NEMA Premium (equivalent to IE3 efficiency), this motor is a reliable power solution for industrial applications requiring strict adherence to American electrical norms.

Adopting a totally enclosed structure with IP54 protection rating, the motor effectively blocks dust, water splashes, and corrosive substances, paired with IC411 self-external fan cooling for rapid heat dissipation. Its housing features finned cast iron or pressed steel (per frame size), ensuring robust structural rigidity and thermal conductivity. The F-class insulation system with B-class temperature rise, UL-approved, extends service life to over 10,000 operating hours, while precision machining and dynamic balancing meet NEMA MG1 Part 7 vibration standards (above Class N), reducing noise to below 75 dB.

The motor covers a power range of 1-800 HP, voltage of 230/460V to 2300-4160V, frequency of 60Hz, and 2-8 poles for flexible adaptation. With a service factor of 1.15 and 150% overload capacity for 60 seconds, it delivers stable performance under heavy loads. It supports bidirectional rotation and inverter control, compatible with IEEE 841 standards, and offers versatile mounting options (F-1, F-2 interchangeable, C-face) for seamless integration into various setups.

Widely applied in pumps, fans, compressors, oilfield equipment, and mining machinery across North America, it meets DOE energy efficiency requirements (certification code: ee CC002A). Backed by TECO’s global quality control and after-sales network, this NEMA-compliant motor balances energy savings, durability, and cost-effectiveness, making it an ideal choice for enterprises targeting the American market and cross-border projects.
