Rheem-Ruud 51-102994-02 Motor

The Rheem-Ruud 51-102994-02 is a professional-grade 1/2 HP blower motor designed for high-static pressure applications in residential HVAC systems. This 1075 RPM furnace motor operates on 120V single-phase power, pulling 6.3 Amps at full load. Engineered with a 48 Nema frame size and an Open Air Over (OAO) enclosure, it ensures optimal heat dissipation during extended run cycles. As a 3-speed permanent split capacitor (PSC) motor, it provides contractors with the flexibility needed to tune airflow for specific ductwork configurations. The unit features sleeve bearings for quiet operation and a 1/2" x 3 1/2" shaft with CCW rotation (lead end). This OEM Rheem replacement motor utilizes a shell-band mount, making it a drop-in solution for compatible air handlers and furnaces requiring reliable 120V HVAC motor performance.

Key Benefits

• Multi-Speed Versatility: Three-speed taps allow for precise CFM adjustments to meet system design requirements.
• Direct OEM Fit: Specifically engineered for Rheem and Ruud equipment, ensuring correct shaft alignment and mounting hole patterns.
• Efficient Cooling: The Open Air Over design utilizes the system's own airflow to maintain safe internal operating temperatures.
• Quiet Operation: Precision-engineered sleeve bearings minimize vibration and mechanical noise within the blower housing.

Common Questions

What capacitor is required for the 51-102994-02?
This PSC motor typically requires a 10 MFD / 370V run capacitor; always verify the rating on the motor nameplate during installation.

Can this motor replace a single-speed blower motor?
Yes, provided the frame size, voltage, and horsepower match, though you must select the appropriate speed tap for your specific static pressure needs.

Is the rotation reversible on this model?
No, this specific part number is fixed for Counter-Clockwise (CCW) rotation from the lead end/back of the motor.
