Rheem-Ruud 51-23102-06 Motor

The Rheem-Ruud 51-23102-06 Motor is a heavy-duty, direct drive blower motor designed for high-static pressure applications in residential and light commercial air handlers. This 1/4 HP HVAC motor operates at 825 RPM across two speeds, providing precise airflow control for cooling and heating cycles. Engineered as a permanent split capacitor motor, it requires a 7.5 MFD / 370V capacitor for optimal torque and energy efficiency. With a NEMA 48 frame size and an Open Air Over (OAO) enclosure, this unit ensures cooling through the airflow it generates, extending the service life of internal components.

For field installations, the 51-23102-06 Rheem replacement motor features a versatile shell-band and shell-screw mount, accommodating various mounting bracket configurations. The 1/2" x 3 5/16" flat shaft is designed for standard HVAC blower wheel hubs, ensuring a secure fit and reducing vibration. Built with sleeve bearings for quiet operation and a CCW rotation (lead end), this 208-230V single phase motor is a drop-in OEM replacement motor for several Rheem, Ruud, and WeatherKing furnace and air handler models.

Key Benefits

• Dual-Speed Logic: Provides 2-speed flexibility to match system CFM requirements for better dehumidification and temperature staging.
• High-Efficiency PSC Design: Maintains a low 2.0-amp draw at 230V, reducing operational costs compared to shaded-pole alternatives.
• Rugged Shaft Construction: The 3.3-inch shaft with a milled flat ensures maximum grip on the blower wheel set screw to prevent slipping.
• Thermal Protection: Features internal overload protection to safeguard the windings against overheating during high-load conditions.
• Quiet Performance: All-angle sleeve bearings are engineered for vibration dampening in residential ductwork systems.

Common Questions

What capacitor is required for the Rheem 51-23102-06?
This motor requires a 7.5 MFD / 370VAC run capacitor (not included). Always verify the capacitor rating on the motor nameplate during installation.

Can I use this to replace a 1075 RPM motor?
No. You must match the 825 RPM rating of your existing motor to maintain correct static pressure and prevent evaporator coil freeze-ups or heat exchanger overheating.

Is this motor reversible?
This specific model is fixed for CCW (Counter-Clockwise) rotation from the lead end. Verify your blower wheel rotation before ordering.
