Rheem-Ruud 51-23017-42 Motor

The Rheem-Ruud 51-23017-42 Motor is a high-performance direct drive blower motor designed for forced-air applications requiring versatile multi-speed configurations. Operating on a 120V single-phase power supply, this PSC motor provides a broad horsepower range from 1/4 to 3/4 HP, allowing it to handle various static pressure requirements in residential and light commercial air handlers. As a 4-speed motor, it offers a functional upgrade over the older 3-speed 51-24272-01 model, providing more precise airflow tuning. Featuring a 48 Nema frame, ball bearings, and an open air over enclosure, this unit is built for continuous duty and heat dissipation. The reversible rotation and shell-band/shell-screw mounting ensure compatibility with existing brackets, while the 1/2" x 5" shaft facilitates easy blower wheel attachment. For technicians sourcing OEM Rheem replacement parts, this motor ensures reliable performance and standard 1075 RPM operation.

Key Benefits

• Increased Versatility: Features 4-speed taps to allow for finer CFM adjustments compared to standard 3-speed legacy motors.
• Superior Bearing Design: Equipped with ball bearings for reduced friction and extended service life in vertical or horizontal orientations.
• Direct Replacement: Designed as the official successor for 51-24272-01, ensuring electrical and physical fitment without field modifications.
• Robust Construction: The 48-frame design with a 1/2" diameter shaft matches industry standards for standardized blower wheel compatibility.

Common Questions

Can this motor replace a 3-speed blower motor?
Yes, the 51-23017-42 is a direct replacement for the 3-speed 51-24272-01. The additional speed tap provides more flexibility for system balancing but can be capped if not required.

What capacitor is required for the 51-23017-42?
As a Permanent Split Capacitor (PSC) motor, it requires a run capacitor. Always check the motor nameplate for the specific microfarad (MFD) rating to ensure proper torque and amperage draw.

Is this motor suitable for outdoor use?
This motor features an Open Air Over (OAO) enclosure, meaning it relies on the air moving through the blower housing for cooling. It should be used in protected indoor fan coil or furnace applications.
