Rheem-Ruud 51-23102-08 Motor

The Rheem-Ruud 51-23102-08 Blower Motor is a high-performance, direct drive blower motor designed specifically for demanding HVACR systems. Built as an OEM Rheem replacement motor, this single-speed unit operates at 825 RPM, delivering 1/2 HP of power to maintain optimal airflow across and through evaporator and condenser coils. Engineered with a NEMA 48 frame size and a permanent split capacitor (PSC) design, it ensures efficient operation and reliability on 208-230V circuits. The CCW rotation (counter-clockwise) and 1/2" x 3 1/4" single-flat shaft provide precise compatibility for specified Rheem and Ruud air handlers and furnaces. For technicians, the Open Air Over (OAO) enclosure and sleeve bearing design facilitate heat dissipation, prolonging component life in standard residential and light commercial environments. Utilizing the shell-band/shell-screw mount, this motor integrates seamlessly into existing blower assemblies, reducing downtime during critical service calls.

• High Torque Efficiency: The PSC motor design provides consistent performance and high efficiency for 208-230V HVAC systems.
• Optimized Airflow Control: Operates at a precise 825 RPM to meet exact manufacturer specifications for static pressure and cubic feet per minute (CFM) requirements.
• Rugged Build Quality: Features a resilient 48 NEMA frame and OAO housing for superior thermal management during continuous duty cycles.
• Streamlined Installation: Direct OEM 51-23102-08 compatibility eliminates the need for field modifications or bracket fabrication.

Is the 51-23102-08 a universal motor?
No. This is a genuine OEM repair part specifically calibrated for Rheem and Ruud equipment. Universal motors often lack the specific 825 RPM profile or mounting patterns required for these proprietary blower housings.

Does this motor require a capacitor?
Yes, as a Permanent Split Capacitor (PSC) motor, a 15/370 MFD run capacitor is typically required. Check the motor nameplate for specific microfarad ratings to ensure proper phase shift and starting torque.

What is the difference between CCW and CW rotation in this model?
This motor is CCW Rotation. Installing a motor with the incorrect rotation will result in zero airflow and can lead to compressor failure or heat exchanger overheating. Always verify the lead-end or shaft-end rotation before final assembly.
