Nidec-US Motors 5458 Motor

The Nidec U.S. Motors 5458 is a professional-grade 1/3-1/6 HP multi-horsepower condenser fan motor engineered for reliability in demanding HVACR applications. Operating at 1075 RPM on a 208-230V single-phase circuit, this PSC (Permanent Split Capacitor) motor is a versatile truck-stock solution for technicians servicing residential and commercial condensing units. The 5-5/8 inch diameter (NEMA 48Y frame) and TEAO (Totally Enclosed Air Over) enclosure ensure the internal components are shielded from dust and moisture, while the SAB (Self-Aligning Bearing) system supports all-angle mounting, making it compatible with various fan shroud configurations. Designed for high-heat environments, it features a 60?C ambient operating temperature rating and automatic thermal protection to prevent winding failure during peak load. The 1/2" x 6" shaft provides ample length for standard fan blade depths, and the reversibility of the electrical leads allows for quick field adjustments to match the required airflow direction.

• Multi-Horsepower Versatility: Replaces both 1/3 HP and 1/6 HP motors, reducing the inventory needed for service calls.
• Durable TEAO Enclosure: The Totally Enclosed Air Over design protects against debris and weather, extending service life in outdoor conditions.
• Flexible Mounting: Compatible with belly band systems and features all-angle mounting capabilities for horizontal or vertical installations.
• Simple Rotation Change: Easily reversible rotation by swapping lead connections ensures compatibility with any condenser fan blade pitch.
• Thermal Security: Integrated auto-reset thermal protection safeguards the motor from overheating due to restricted airflow or capacitor failure.

What size capacitor is required for this motor?
This motor typically requires a 7.5 MFD / 370V run capacitor for optimal performance (sold separately). Always check the motor nameplate during installation to verify the specific rating.

Can this motor be mounted in any orientation?
Yes, the self-aligning bearing (SAB) system is designed for all-angle mounting, allowing the motor to be installed with the shaft up, down, or horizontally without compromising lubrication.

Is this a direct replacement for 48-frame condenser motors?
The 5-5/8 inch diameter corresponds to the standard NEMA 48Y frame, making it a suitable replacement for most OEM 48-frame condenser fan applications matching the electrical specs.
