Nidec-US Motors 3737 Motor

The Nidec-US Motors 3737 is a heavy-duty, 1/3 HP condenser fan motor engineered for demanding high-voltage 460V industrial and commercial HVAC applications. Operating at 1075 RPM, this Permanent Split Capacitor (PSC) motor features a NEMA 48Y frame and a Totally Enclosed Air Over (TEAO) enclosure, ensuring the internal windings remain protected from environmental debris while relying on the fan’s airflow for thermal management. Built with high-grade ball bearings, the 3737 is designed for continuous duty and reduced friction in vertical or horizontal orientations. This unit is the direct technical replacement for FEH1036S and S1-024-25913-700, utilizing a standard 1/2-inch diameter shaft and flexible reversible rotation lead wires to match specific blade configurations. The 1.3 Amp draw and stud-mount design make it a reliable drop-in for 460V HVAC motor replacement projects, maintaining system static pressure and heat rejection efficiency in critical cooling cycles.

• Enhanced Durability: Features a TEAO design and all-angle ball bearings to extend service life in harsh outdoor environments.
• Versatile Application: Explicitly engineered as a direct replacement motor for OEM part numbers FEH1036S and S1-024-25913-700.
• Installation Flexibility: Reversible rotation and universal stud mount patterns allow for rapid field adaptation.
• Optimized Efficiency: The 1075 RPM condenser motor speed ensures consistent airflow across the coils to prevent high-head pressure issues.

Common Questions

Can the 3737 be used in 230V systems?
No, this is a dedicated 460Vac single phase motor. Applying lower voltage will result in insufficient torque and motor failure.

What capacitor is required for this motor?
This motor requires a 7.5 MFD / 440V capacitor (not included) to ensure proper starting torque and running amperage.

Is this motor suitable for belt-drive applications?
No, this is a direct drive condenser motor. The 48Y frame and shaft are designed for mounting a fan blade directly to the 1/2" shaft.
