Carrier HD52AZ001 Motor

The Carrier HD52AZ001 is a commercial-grade, three-phase condenser fan motor engineered for high-demand heat rejection in large-scale HVACR systems. Operating at 1140 RPM with a versatile dual-voltage rating of 208-230/460V, this 1 HP induction motor provides the high torque and balanced load handling required for heavy-duty industrial applications. As a 56-frame motor, it features a 5/8-inch keyed shaft and a totally enclosed air over (TEAO) design to protect internal windings from environmental contaminants and moisture common in rooftop installations.

For service technicians, this unit is the direct replacement for HD52AK001 and the GE 5K49ZN6254AS, ensuring exact physical mounting and electrical alignment without the need for bracket modifications. Built with NEMA Design standards and Class F insulation, it is thermally protected and rated for continuous air over duty. Whether you are performing a Carrier motor replacement on a failing 3-phase unit or upgrading for improved HVAC motor efficiency, this OEM component maintains the original system performance specifications and airflow requirements.

Key Benefits

• OEM Compatibility: Precision-engineered as a drop-in replacement for the Carrier HD52AK001 to simplify field installation.
• Dual-Voltage Versatility: Supports 208-230V or 460V 3-phase power configurations for broader application across commercial sites.
• Industrial Durability: Robust 56-frame construction with high-grade steel/aluminum housing resists vibration and extends service life.
• Enhanced Thermal Protection: Integrated thermal overload protection prevents damage during high-ambient operation or restricted airflow conditions.
• Stable Airflow: Constant 1140 RPM operation ensures consistent heat exchange across the condenser coils.

Common Questions

Can I use this motor to replace a single-phase unit?
No. This is a 3-phase induction motor. Attempting to wire this to a single-phase power supply will result in immediate failure and potential damage to the electrical control circuit.

What should I check if the new motor won't start after installation?
Verify the incoming voltage to all three legs of the contactor. Since this is a three-phase motor, it does not use a standard start/run capacitor, so ensure the contactor or defrost control board is engaging correctly and the rotation direction is set for your specific fan blade pitch.

Is this motor compatible with 50Hz systems?
Yes, this motor carries an alternate rating for 200V/400V operation at 50Hz, though technical performance metrics like RPM and amperage may vary from the standard 60Hz 1140 RPM rating.
