Baldor .5 HP 1735 RPM 3-Phase Motor

Baldor-Reliance Super-E Premium Efficient AC Motor – 0.5 HP, 3-Phase, 1735 RPM, 230/460 Volts, 56C Frame, TEFC Enclosure (MPN: VEM3538)

The Baldor-Reliance VEM3538 is an industrial-grade, commercial-duty 0.5 horsepower alternating current (AC) induction motor precision-engineered for continuous-operation industrial processing lines and commercial machinery systems. Part of the legendary Super-E premium efficiency product class, this low-vibration three-phase motor is wound to operate at a nominal synchronous load rate of 1735 RPM, delivering balanced mechanical torque under heavy-duty startup curves. Configured with a standardized NEMA 56C face-mount frame design, the motor is housed within a Totally Enclosed Fan Cooled (TEFC) steel band shell that isolates internal stator laminations from outdoor air contamination, ambient moisture, and flying warehouse debris, making it a rugged choices for automated manufacturing configurations.

Technical Performance and Design

• Premium Efficient Super-E Winding Architecture: Engineered with high-purity copper windings that exceed standard efficiency baselines, helping to minimize electrical operating temperatures, slash facility power expenses, and reduce operational carbon footprints during round-the-clock commercial manufacturing cycles.

• Totally Enclosed Fan Cooled (TEFC) Protection: Encased in a rugged steel band housing equipped with an external rear fan and a protective shroud. The cooling fan continuously forces high-velocity ambient air across the external cooling fins, rapidly shedding heat while keeping internal windings clear of airborne particulate, lint, and moisture.

• Universal NEMA 56C Face Mounting: Manufactured with standard 56C frame dimensions, featuring a precision-machined face flange paired with integrated mounting bolt patterns. This footprint allows for direct mechanical coupling onto fluid pumps, industrial gearboxes, chemical agitators, and inline conveyor drives.

• Heavy-Duty Ball Bearing Layout: Outfitted with oversized, factory-greased shielded ball bearings on both the drive end and opposite drive end shafts. This internal bearing matrix handles high radial and axial load forces, keeping noise thresholds low and extending maintenance intervals.
