Rheem-Ruud 51-23052-11 Motor

The Rheem-Ruud 51-23052-11 is a high-performance direct drive condenser fan motor designed for heavy-duty HVAC applications. This 1/2 HP condenser motor operates at 208-230V, delivering a consistent 1075 RPM at a single speed. Engineered with a NEMA 48 frame and a totally enclosed air over (TEAO) enclosure, it provides superior protection against environmental debris and moisture, ensuring long-term reliability in the field. The 51-23052-11 Rheem motor utilizes a permanent split capacitor (PSC) design and requires a 10 MFD/370V capacitor for optimal starting torque and efficiency. Featuring sleeve bearings and a reversible rotation capability, this OEM replacement motor offers versatile installation options, including shell-band, shell-screw, or thru-bolt mounting. The 1/2" diameter by 5" long shaft ensures compatibility with standard fan blades, making it a critical component for restoring system head pressure and heat transfer efficiency in residential and light commercial condensing units.

Key Benefits

• Universal Mounting: Supports shell-band, shell-screw, and thru-bolt configurations for seamless field integration.
• Environmental Protection: The totally enclosed housing prevents dust and rain ingress, extending the service life of internal components.
• Optimized Performance: Sustains a steady 1075 RPM to maintain correct CFM across the condenser coil.
• Reversible Operation: Easily adjustable rotation allows this motor to replace multiple fixed-rotation SKUs in your service truck inventory.

Common Questions

What capacitor is required for the Rheem 51-23052-11?
This motor requires a 10 MFD 370-volt run capacitor to operate within factory specifications. Using an incorrectly sized capacitor can lead to overheating and premature winding failure.

Can I use this motor to replace a 1/3 HP or 1/4 HP unit?
While a higher horsepower motor can technically drive a smaller load, it is essential to match the RPM and frame size exactly to ensure the fan blade pitch does not overload the motor or cause vibration issues.

Is this motor suitable for salt-air environments?
Yes, the totally enclosed enclosure provides better protection than open drip-proof designs, though regular maintenance is recommended for all outdoor electrical components in coastal regions.
