Baldor KM3457 0.33 HP Three-Phase Induction Motor

The Baldor-Reliance KM3457 is a 0.33 HP, three‑phase induction motor designed for continuous, totally enclosed non‑ventilated (TENV) service in a 56C steel frame. It runs at 60 Hz with a nominal speed of 3450 rpm (3600 rpm synchronous) and supports 230/460 VAC input, with measured currents of about 1.4 A at 230 V, 0.7 A at 460 V, and 1.6 A at 208 V. Built for general‑purpose use, this motor employs a TE(N)V enclosure, carries a continuous (F1) duty rating, and lists an efficiency around 72% at full load; bearings are lubricated with Polyrex EM and rated for temperatures from -20°F to 300°F, with an ambient rating up to 40°C. The KM3457 is configured for mounting on a C‑face (56C) application and ships without an auxiliary box, making it suitable for conveyors, fans, pumps, and other light‑duty industrial drives that require a compact, reliable 1/3 HP, 3‑phase solution.
