Rheem-Ruud 51-100999-03 Condenser Motor

The Rheem-Ruud 51-100999-03 Condenser Motor is a precision-engineered OEM replacement motor designed for high-static outdoor applications. This 1/6 HP condenser fan motor operates at 208-230V and delivers 1075 RPM at a single speed, pulling a nominal 0.73 Amps. Utilizing a Permanent Split Capacitor (PSC) design, it requires a 3 MFD / 370V capacitor for optimal torque and efficiency. The motor features a NEMA 48 frame size with a Totally Enclosed (TEAO) housing to protect internal windings from environmental debris and moisture. The 1/2" x 3 7/16" flat shaft and CCW lead end rotation ensure compatibility with specific Rheem and Ruud residential condensing units. Built with sleeve bearings for quiet operation and a shell-band mount for secure seating, this 48 frame HVAC motor provides the reliability needed for critical cooling cycles. Professional installation is recommended to ensure proper lead routing and capacitor matching to maintain HVAC system performance.

• Direct OEM Fit: Ensures correct shaft length and bolt patterns for Rheem and Ruud units, reducing field modification time.
• High Efficiency: The low amperage draw of 0.73A minimizes energy consumption while maintaining peak CFM output.
• Weather Protection: Totally enclosed enclosure prevents premature failure caused by rain, dust, and outdoor contaminants.
• Quiet Operation: Sleeve bearing design reduces vibration and acoustic output during high-demand cooling periods.

What capacitor does the Rheem 51-100999-03 use?
This motor requires a 3 MFD / 370V run capacitor for proper startup and operational efficiency.

Is this motor compatible with 460V systems?
No, this specific model is rated for 208-230V single-phase systems only. Check your data plate before installation.

Can I change the rotation of this motor?
This motor is fixed at CCW (Counter-Clockwise) rotation at the lead end. Ensure your fan blade pitch matches this rotation for proper airflow.
