Daikin-McQuay JADQ5937 Motor

The Daikin-McQuay JADQ5937 Motor is a high-performance 1/4 HP condenser fan motor engineered for reliability in demanding commercial and residential HVACR applications. Operating at 120V and a sustained 1075 RPM, this single-phase AC motor is built on a standard 48 frame chassis, ensuring a direct-fit replacement for numerous McQuay and Daikin air handling and condensing units. Designed with technical precision, the JADQ5937 features a Permanent Split Capacitor (PSC) design that optimizes energy efficiency and electrical stability during peak load conditions.

For technicians performing a field swap, this OEM replacement motor maintains the exact physical footprint and electrical parameters required to preserve system airflow balance and prevent compressor overheating. The JADQ5937 is thermally protected and built to withstand the high ambient temperatures common in outdoor condenser environments. When replacing this unit, verify your run capacitor specifications and lead wire orientation to ensure seamless integration with the existing control board or contactor setup.

Key Benefits

• OEM Compatibility: Precision-matched for Daikin and McQuay equipment, eliminating the need for mounting bracket modifications.
• Standardized 48 Frame: Features a 5.6-inch diameter housing, the industry standard for HVAC fan motors, ensuring physical clearance.
• Optimized Performance: Delivering 1/4 HP at 1075 RPM provides the necessary static pressure to pull air through fouled or dense coils.
• Durable Construction: Built for continuous duty in condensing units with advanced insulation to handle voltage fluctuations.
• Efficient Electrical Profile: The 120V single-phase configuration allows for straightforward wiring in standard HVACR electrical circuits.

Common Questions

Does the JADQ5937 motor include a new run capacitor?
Standard HVAC replacement motors typically require a separate capacitor. Always check the motor nameplate for the required MFD rating to ensure the 1/4 HP motor starts and runs with the correct phase shift.

Can I use a 230V motor as a substitute for this 120V model?
No, this motor is specifically wound for 120V operation. Using an incorrect voltage will lead to immediate winding failure or control board damage. Always match the 120V 1Ph spec exactly.

Is this motor reversible in the field?
While many 48 frame motors are reversible, this Daikin-McQuay OEM part is built to specific rotation requirements. Confirm the rotation (CW or CCW) against your existing blade pitch before installation.
