Rheem-Ruud 51-100998-07 Motor

The Rheem-Ruud 51-100998-07 is a 1/3 HP 1075 RPM 460V Condenser Fan Motor designed specifically for demanding HVACR applications requiring high-voltage reliability. This PSC (Permanent Split Capacitor) motor features a single-speed design and is engineered for outdoor condenser units, facilitating efficient heat rejection. It operates on a 460-volt, single-phase power supply, making it a critical component for commercial and industrial OEM replacement motor applications. Note that the 51-100998-31 is the direct replacement for the 51-100998-07 model, offering identical mounting specifications and performance curves to ensure seamless integration into existing Rheem and Ruud HVAC units. When installing this HVAC blower motor, ensure a 7.5 MFD / 370V capacitor is utilized to maintain proper torque and amperage draw. The condenser fan motor replacement process requires strict adherence to lead identification to prevent phase-related performance issues in high-ambient conditions.

• Direct OEM Compatibility: Specifically engineered as a drop-in replacement for Rheem and Ruud systems, eliminating the need for field modifications or bracket adjustments.
• High-Voltage Durability: Rated for 460V operation, providing stable performance in commercial power environments and reducing the risk of winding failure.
• Standardized Frame Size: Features a standard 48-frame diameter for compatibility with existing mounting rings and rain shields.
• Thermal Protection: Includes internal thermal overload protection to prevent motor burnout during restricted airflow or high-head pressure events.

Is the 51-100998-31 fully compatible with my existing 51-100998-07 mount?
Yes, the 51-100998-31 is the official superceding part number and maintains the exact physical dimensions, shaft length, and bolt pattern as the 07 revision.

Which capacitor is required for this 460V motor?
This motor typically requires a 7.5 MFD / 370V-440V run capacitor. Always check the motor nameplate during installation to verify the exact capacitance requirements for optimal efficiency.

Can this motor be used in 230V applications?
No, this is a dedicated 460V motor. Applying lower voltage will result in insufficient torque and eventual motor failure.
