Baldor Electric Company M3457 Three Phase AC Motor

Built by Baldor as part of the Baldor‑Reliance general‑purpose line, the M3457 is a 1/3 HP, 3450 RPM, three‑phase AC motor rated for both 230 and 460 VAC at 60 Hz. Housed in a 48-frame, Totally Enclosed Non‑Ventilated (TENV) enclosure, this foot‑mounted unit is designed for reliable continuous‑duty operation in standard industrial environments. It’s a compact, versatile choice for driving fans, pumps, conveyors, or small machine tools where a dual‑voltage, 3‑phase motor is advantageous. The M3457’s 48‑frame size matches common mounting footprints and its dual‑voltage operation supports flexible integration with available power supplies without requiring a separate transformer, making it a straightforward replacement or upgrade for compatible Baldor‑equipped equipment.
