Rheem-Ruud 51-23102-07 Motor

The Rheem-Ruud 51-23102-07 Blower Motor is a heavy-duty, 1/3 HP permanent split capacitor motor engineered specifically for residential and light commercial HVAC applications. Operating at 208-230V and a low-speed 825 RPM, this dual-speed motor provides precision airflow control while maintaining a standard 2.8 Amps draw. Built on a NEMA 48 frame, it features an Open Air Over (OAO) enclosure to ensure internal components stay cool during high-static operation. The CCW rotation (counter-clockwise) and sleeve bearing design facilitate quiet, low-vibration performance. Mounting is versatile via shell-band or shell-screw configurations, accommodating a standard 1/2" x 2" shaft. This OEM replacement motor is essential for restoring factory-spec efficiency in Rheem condenser fan motors and air handlers where reliability is non-negotiable for the contractor.

Key Benefits for HVAC Professionals

• Durable Construction: Features a sleeve bearing system and OAO enclosure for superior heat dissipation in demanding environments.
• Direct Fit Compatibility: Standard NEMA 48 frame and 2-speed capability ensure seamless integration with existing control boards and fan blades.
• Reliable Operation: Rated for 208-230Vac single phase, providing a stable electrical profile to maximize the lifespan of the capacitor and contactor.

Common Questions

Is the 51-23102-07 a direct replacement for my blower unit?
This motor is a standard OEM replacement for many Rheem and Ruud units. Always verify the NEMA 48 frame size and 825 RPM rating against your existing data plate to ensure proper torque and fitment.

Does this motor require a specific capacitor?
As a permanent split capacitor motor, it requires a run capacitor (typically 5 MFD/370V, though you must check the motor label for exact specs) to operate within its design parameters.

Can I use this motor in a vertical or horizontal orientation?
Yes, the shell-band/shell-screw mount and OAO design allow for versatile installation, provided the motor remains in the airflow path for proper cooling.
