Carrier HC52TQ145 Motor

The Carrier HC52TQ145 Blower Motor is a high-performance, single-phase OEM replacement motor engineered for heavy-duty air circulation in furnace and air handler applications. This 1 HP, 115V permanent split capacitor (PSC) motor operates at a nameplate 1075 RPM and features 5-speed taps to allow for precise airflow tuning across varying static pressures. Built with a rugged 48Y frame and open air-over (OAO) enclosure, the HC52TQ145 motor is designed to replace legacy components like the Carrier HC45TQ145 and HC51TQ145, ensuring a drop-in fit without the need for mounting modifications.

For contractors servicing Carrier, Bryant, and Payne HVAC systems, this 1 HP furnace blower motor provides the torque necessary to overcome high-resistance ductwork while maintaining efficiency. It utilizes a 1/2-inch diameter shaft and requires a 35 MFD / 440 VAC run capacitor for optimal startup and operational stability. By utilizing this genuine Carrier part, technicians ensure optimal compatibility with factory control boards and blower wheel assemblies, reducing vibration and preventing premature bearing failure common with universal alternatives.

• Multi-Speed Flexibility: 5-speed taps enable precise CFM adjustments to match system-specific heating and cooling load requirements.
• Direct OEM Compatibility: Seamlessly replaces HC45TQ145 and HC51TQ145, maintaining original factory performance and electrical specifications.
• High-Torque Performance: 1 HP output at 1075 RPM provides robust airflow for large-tonnage residential and light commercial equipment.
• Industrial-Grade Build: Features a durable 48Y frame and CCW rotation (lead end) for long-term reliability in demanding environments.

Is the HC52TQ145 a direct replacement for the older HC45TQ145 model?
Yes, the Carrier HC52TQ145 is the factory-authorized superseding part for the HC45TQ145. It matches the physical dimensions, electrical requirements, and speed profiles of the original motor.

What capacitor is required for this 1 HP blower motor?
This motor requires a 35 MFD / 440 Volt run capacitor. It is recommended to install a new capacitor alongside the motor to ensure the start windings operate within spec.

Can this motor be used in applications requiring variable speed control?
This is a 5-speed PSC motor, not an ECM. While it offers 5 discrete speed taps for selection during installation, it is designed for use with standard multi-speed control boards rather than variable-frequency drives or PWM signals.
