Baldor Motor VEM31120 Motor

The Baldor-Reliance VEM31120 is a high-performance 1.5 HP three-phase AC motor designed for demanding commercial and industrial pump applications. Operating at a 3450 RPM synchronous speed, this NEMA 56C frame motor features a c-face mount with feet, providing a rigid base for maximum stability. This TEFC (Totally Enclosed Fan Cooled) motor is engineered for continuous duty, utilizing 230/460V dual-voltage operation to accommodate standard power configurations. The VEM31120 general purpose motor is built with a steel frame and high-grade ball bearings to handle axial and radial loads in high-speed environments. Technical specifications include a 1.15 service factor, Class F insulation, and 60Hz frequency compatibility, ensuring reliable performance in HVACR pump systems and fluid handling equipment. Designed for durability, this industrial motor maintains high torque efficiency across 1.5 horsepower outputs, making it a standard replacement for standard 56C pump-mount configurations.

• High-Speed Performance: Delivers a consistent 3450-3500 RPM for high-head centrifugal pump applications.
• Three-Phase Efficiency: Optimized for 230/460V 3-phase power, reducing amperage draw and heat generation compared to single-phase units.
• Durable Construction: Features a rugged 56C frame motor design with a TEFC enclosure to protect internal windings from dust and moisture.
• NEMA Compliant: Adheres to strict NEMA standards for mounting dimensions and shaft alignment, ensuring drop-in compatibility.

Common Questions

What are the wiring requirements for the VEM31120?
This motor supports dual-voltage 230V or 460V 3-phase power. Ensure your controller or VFD is configured for the correct voltage and that the lead connections inside the conduit box match the nameplate diagram for your specific line voltage.

Can this motor be used with a Variable Frequency Drive (VFD)?
Yes, the Baldor VEM31120 is inverter-ready; however, contractors should verify the speed range and constant torque requirements to ensure the TEFC cooling remains effective at lower frequencies.

Is the 56C frame compatible with standard flange-mount pumps?
The NEMA 56C frame includes a standardized 4.5-inch pilot and a 5/8-inch shaft, making it directly compatible with most C-face pump housings and gear reducers used in industrial HVACR systems.
