Rheem-Ruud 51-100998-30 Motor

The Rheem-Ruud 51-100998-30 Motor is a high-performance, single-phase HVAC condenser motor designed specifically for demanding outdoor environments. This 1/3 HP condenser fan motor features a standard NEMA 48 frame and operates at 1075 RPM, providing the consistent torque required for efficient heat dissipation. Engineered as a direct OEM upgrade, the 51-100998-30 replaces the 51-100998-05 model and is compatible with a broad range of Rheem, Ruud, and WeatherKing 10-SEER to 14-SEER outdoor units.

Built with double-sealed ball bearings and thermal overload protection, this 208-230V 1075 RPM motor is optimized for longevity and quiet operation across 50/60 Hz frequencies. The motor utilizes a permanent split capacitor (PSC) design, typically requiring a 5 MFD / 370V run capacitor for optimal startup and running efficiency. With a 1/2-inch diameter shaft and CCW rotation (facing the lead end), this OEM Rheem replacement motor ensures a seamless drop-in fit for technicians performing field service or preventative maintenance.

• OEM Compatibility: Serves as the factory-authorized direct replacement for the 51-100998-05 motor, ensuring lead lengths and mounting alignments match the original configuration.
• Enhanced Thermal Response: Integrated internal thermal protection prevents winding failure during restricted airflow or high-ambient peak loads.
• Versatile Application: Suitable for a vast array of Rheem-Ruud condensers, including RAKB, RALC, RAMC, and RAPC residential series.
• Reliable Construction: Features a durable 48-frame shell with high-grade ball bearings to minimize vibration and power consumption.

Is this a direct replacement for my older 51-100998-05 motor?
Yes, the 51-100998-30 is the designated manufacturer-approved successor to the 51-100998-05, maintaining identical electrical and mechanical specifications.

What rotation direction does this motor support?
This motor is lead-end CCW (counter-clockwise) rotation, which is standard for the majority of residential outdoor fan configurations in the Rheem-Ruud catalog.

Does this motor require a new run capacitor?
Technicians recommend inspecting the existing capacitor when replacing any PSC motor. This unit is designed for use with a 5 MFD / 370V capacitor.
