Rheem-Ruud 51-23609-04 Motor

The Rheem-Ruud 51-23609-04 Motor is a high-performance direct drive blower motor designed for reliable air handling in residential and light commercial HVAC systems. This 1/2 HP 1075 RPM motor operates on 208-230V single phase power, pulling 2.4 Amps at full load. Built with a 48 Nema frame size, it features an Open Air Over (OAO) enclosure and sleeve bearings for quiet, long-term operation. As a 3-speed blower motor, it allows for precise airflow tuning to meet specific static pressure requirements. The CCW rotation (lead end) and 1/2" x 3" shaft make it a standard drop-in replacement for failed induction motors in compatible furnace and air handler units. This Permanent Split Capacitor (PSC) motor requires a 7.5 MFD/370V capacitor for optimal torque and efficiency, ensuring seamless integration with existing control boards and multi-speed tap configurations.

Key Specifications and Benefits

• Multi-Speed Versatility: Three distinct speed taps allow for customized heating and cooling CFM adjustments.
• Durable Construction: Features a shell-band mount and sleeve bearing design optimized for vibration reduction.
• Thermal Protection: Internal automatic reset thermal overload protection prevents winding burnout during high-load scenarios.
• Efficient Performance: PSC motor technology provides consistent efficiency across 208V and 230V applications.

Common Questions

What capacitor is required for the Rheem 51-23609-04?
This motor is engineered to operate with a 7.5 MFD / 370 VAC run capacitor to maintain proper phase shift and torque.

Can I use this to replace a single-speed motor?
Yes, provided the NEMA 48 frame, voltage, and shaft dimensions match; however, you must ensure the CCW rotation aligns with your blower wheel configuration.

Is this motor suitable for outdoor use?
No, this is an Open Air Over (OAO) motor intended for indoor air handler or furnace compartments where the airflow cools the motor windings.
