Nidec-US Motors 1873H Motor
The Nidec US Motors 1873H is a high-performance condenser fan motor engineered for demanding outdoor HVACR applications. This 1/6 HP motor operates on 208-230V single-phase power at a precise 825 RPM, making it an ideal choice for high-efficiency systems requiring slower fan speeds to maximize heat transfer. Built on a 48Y frame with a 1/2-inch diameter shaft, it features a totally enclosed air over (TEAO) enclosure to protect internal windings from environmental contaminants. This permanent split capacitor (PSC) motor utilizes double-sealed ball bearings for extended service life in vertical shaft-up or shaft-down orientations. With an automatic reset thermal overload protector and Class B insulation, the 1873H ensures reliable cycling under high ambient temperatures. For field replacements, ensure a 5 MFD / 370V capacitor is paired with this unit to maintain torque specifications and prevent premature winding failure.
- Low-Speed Efficiency: The 825 RPM rating is optimized for larger condenser coils, reducing noise and improving subcooling.
- Robust Environmental Protection: The TEAO design and 48-frame chassis prevent moisture and debris ingress in outdoor units.
- Universal Mounting: Extended thru-bolts and a versatile 48Y frame allow for seamless integration into various OEM condensing unit motor brackets.
- Reversible Rotation: Features easy-to-use reversing leads, allowing for quick adjustment to clockwise or counter-clockwise requirements in the field.
Common Questions
What capacitor is required for the US Motors 1873H?
This motor requires a 5 MFD / 370V run capacitor. Using an incorrectly rated capacitor can lead to overheating and reduced motor life.
Can the 1873H replace a 1075 RPM motor?
It is not recommended to down-speed a 1075 RPM application to 825 RPM unless specified by the manufacturer, as it will significantly alter the CFM and head pressure of the system.
Is this motor suitable for vertical installation?
Yes, the 1873H is equipped with ball bearings and is rated for multiple mounting positions, including shaft-up or shaft-down configurations.
