Rheem-Ruud 51-24272-01 Motor

The Rheem-Ruud 51-24272-01 Motor is a high-performance 1/2 HP blower motor engineered for precise performance in residential gas furnaces and air handlers. Operating on 120V single-phase power, this PSC (Permanent Split Capacitor) motor features a 48 Nema frame size and delivers a consistent 1075 RPM. With 3-speed versatility and a current draw of 7.9 Amps, it provides the necessary airflow modulation for optimized static pressure management. The unit utilizes a 1/2" x 3 3/4" shaft and is designed for CCW rotation (Counter-Clockwise) as viewed from the lead end. Constructed with an Open Air Over (OAO) enclosure and reliable sleeve bearings, this motor is built for shell-band or shell-screw mounting, ensuring a direct fit for many Protech and Rheem air distribution systems. Contractors frequently specify this genuine OEM replacement motor to restore factory airflow specifications while maintaining system electrical integrity.

• Direct OEM Fit: Drop-in HVAC blower motor replacement for Rheem and Ruud equipment ensures correct capacitor sizing and mounting without field modification.
• Multi-Speed Flexibility: Three distinct speed taps allow for fine-tuning CFM to meet specific system requirements and ductwork configurations.
• Thermal Efficiency: The Open Air Over design leverages the system's own airflow to maintain low operating temperatures for the internal windings.
• Quiet Operation: Precision-machined sleeve bearings reduce vibration and noise transfer throughout the ducting.

Technical FAQ

What capacitor is required for the 51-24272-01?
This permanent split capacitor motor must be paired with the specific MFD/uF rating indicated on the motor nameplate (typically 10 MFD/370V) to ensure proper starting torque and amp draw.

Can this motor replace a 115V or 230V unit?
This is a dedicated 120Vac motor. It is not compatible with 230V systems. Always verify line voltage at the control board or transformer before installation.

How do I confirm the rotation of my existing blower?
This model is rated for CCW rotation. When matching components, confirm rotation by looking at the motor from the lead end (back of the motor) rather than the shaft end to ensure proper blower wheel orientation.
