Heatcraft Refrigeration 25314601S Motor

The Heatcraft Refrigeration 25314601S Motor is a high-performance 48 frame motor engineered for demanding commercial refrigeration environments. This 1/3 HP replacement motor is a direct OEM component for Heatcraft and McQuay systems, operating at 1075 RPM on a 460V single-phase power supply. Built by Marathon (model FWE 48A11011046A), it features a 1.0 service factor and is rated for continuous duty, ensuring it handles the thermal loads of walk-in coolers and condenser fan assemblies without premature failure. The permanently lubricated ball bearings and robust electrical winding design offer stable performance in high-static pressure applications. When replacing an existing 25314601 or 25314601S, this motor provides the exact torque profile and mounting compatibility required to maintain factory-spec airflow and system efficiency. This is a critical component for technicians prioritizing uptime in cold storage and HVACR infrastructure.

• Durability: Continuous duty rating ensures the motor thrives in 24/7 evaporator and condenser fan cycles.
• Standardized Mounting: Features a NEMA 48 frame for universal bracket alignment within standard fan shrouds.
• Precision Airflow: The 1075 RPM speed is calibrated for optimal CFM delivery across refrigeration coils.

Common Questions

Is the 25314601S a multi-voltage motor?
No, this motor is specifically engineered for 460V single-phase applications. Verification of the power supply at the contactor is recommended before installation.

Does this motor include the run capacitor?
Most Marathon FWE 48A11011046A models require a specific MFD-rated capacitor. We recommend checking the nameplate on the old unit to determine if a new run capacitor is needed for this 1/3 HP motor.

Can this be used for both evaporator and condenser fans?
Yes, as long as the 1075 RPM and 1/3 HP specifications meet the original fan blade pitch and airflow requirements, this Heatcraft motor is suitable for both applications.
