Rheem-Ruud 51-23555-02 Motor

The Rheem-Ruud 51-23555-02 is a professional-grade 3/4 HP blower motor designed for high-static pressure applications in residential and light commercial HVAC systems. This PSC (Permanent Split Capacitor) motor operates at 1075 RPM across 3 speeds, allowing for precise airflow adjustment to meet specific CFM requirements. Built with a NEMA 48 frame size and an Open Air Over (OAO) enclosure, it utilizes sleeve bearings for quiet operation and a shell-band mount for standard housing integration. Drawing 5.4 Amps at 208-230V, this direct drive blower motor features a 1/2" x 2-3/4" shaft and CW rotation. As a direct OEM replacement motor, it ensures electrical compatibility and mounting alignment for Rheem and Ruud air handlers and furnaces, eliminating the need for field modifications during service calls.

• Multi-Speed Versatility: The 3-speed configuration provides flexibility for heating and cooling stages, ensuring optimal HVAC airflow performance.
• Industrial Build Quality: Features internal thermal protection and an OAO design to dissipate heat effectively during continuous operation.
• Exact Fit Compatibility: Specifically engineered as a Rheem furnace motor replacement, maintaining the original equipment manufacturer’s specifications.
• Efficient PSC Design: The Permanent Split Capacitor technology offers a balance of high starting torque and energy efficiency.

How do I verify if this 3/4 HP HVAC motor fits my air handler?
Check your existing motor's data plate for the part number 51-23555-02, or verify that the frame size is 48, the voltage is 208-230V, and the shaft dimensions are 1/2" x 2-3/4".

Which capacitor is required for the Rheem-Ruud 51-23555-02?
This single phase motor requires a specific MFD run capacitor (typically 10 MFD/370V) as indicated on the motor's nameplate to ensure proper torque and amperage draw.

Can I use this motor to replace a different brand of blower motor?
Yes, provided the NEMA 48 frame, 1075 RPM speed, CW rotation, and electrical ratings match your current system's requirements.
