Mcquay Daikin MOTOR973 Motor
The McQuay Daikin MOTOR973 is a purpose-built 1/4 HP replacement blower motor engineered for specific 277V terminal equipment and fan coil applications. This PSC direct drive motor operates at a nominal 1075 RPM and features a 3-speed configuration, allowing technicians to precisely calibrate airflow to match the external static pressure requirements of the system. Designed with a standard 48-frame diameter and a resilient mount, the MOTOR973 serves as an exact OEM HVAC replacement motor for Daikin and legacy McQuay units, ensuring mechanical alignment and electrical compatibility without the need for field modifications or bracket fabrication. Utilizing high-grade windings and integrated thermal overload protection, this permanent split capacitor motor maintains efficiency across all speed taps. For contractors performing multi-speed motor troubleshooting, the MOTOR973 provides a reliable solution for restoring factory-specified CFM performance in high-voltage commercial environments.
Key Benefits for Technicians- Daikin OEM Specification: Ensures drop-in compatibility with legacy McQuay air handlers, eliminating mounting issues.
- Three-Speed Flexibility: Offers High, Medium, and Low speed taps for optimized field balancing and comfort control.
- High-Voltage Rating: Specifically wound for 277V 1-phase power, common in commercial lighting and HVAC circuits.
- 48-Frame Construction: Standardized housing size facilitates easy installation within existing blower housings.
Is a capacitor included with the MOTOR973?
This motor requires a specific run capacitor to ensure proper torque and amperage draw. Verify the microfarad rating on the existing capacitor or motor nameplate during installation.
Can this motor be used in a 208-230V application?
No, this motor is strictly rated for 277V operation. Running it on lower voltage will result in insufficient torque and premature winding failure.
What is the standard rotation for this replacement?
The MOTOR973 is typically configured for Clockwise Lead End (CWLE) rotation, matching standard McQuay centrifugal blower wheel orientations.
