Nidec-US Motors 5469 Blower Motor

The Nidec-US Motors 5469 Blower Motor is a high-performance Rescue Permanent Split Capacitor (PSC) motor engineered for professional HVACR contractors. This multi-horsepower unit serves as a direct cross-reference for 51-21543-01, providing a versatile solution for a wide range of air handler and furnace applications. Operating at 208-230 VAC and 825 RPM, this 4-speed motor is specifically designed to replace blowers rated between 1/3, 1/4, and 1/8 HP. The 48Y NEMA frame and reversible rotation allow for standard field adjustments, ensuring compatibility with various fan and blower configurations. Built with self-aligning sleeve bearings and an Open Air Over (OAO) enclosure, this motor maintains thermal stability during continuous duty. The 1/2" diameter shaft and stud mount design simplify the replacement process in residential and light commercial equipment.

Common Installation Questions

What is the proper capacitor for this motor?
The motor is designed for use with a 7.5 MFD / 370 VAC capacitor (often included) to ensure correct starting torque and running amperage.

Can this motor be used in totally enclosed applications?
No, this is an Open Air Over (OAO) motor and requires airflow from the blower wheel to pass over the motor body for proper cooling.

How do I change the rotation on the 5469 motor?
Rotation is easily reversed by swapping the two leads in the motor connector according to the diagram on the rolled steel housing.
