Carrier HC45AE116 Motor

The Carrier HC45AE116 is a professional-grade 3/4 HP Blower Motor engineered as a Factory Authorized Part to maintain the precise performance standards of Carrier, Bryant, and Payne HVAC systems. This 115V Single Phase Motor features a 4-speed configuration and operates at 1075 RPM, providing the high-torque output necessary for heavy-duty air distribution in residential and light commercial furnaces. Built with a NEMA 48 frame and a permanent split capacitor (PSC) design, this motor is a reliable OEM replacement motor for the 58SXA120-100LG and other compatible models. As a direct-drive solution, it resolves common system issues such as excessive bearing noise or total blower failure, ensuring the airflow remains within the manufacturer’s specified CFM range. This HVAC blower motor is tested for efficiency and durability to handle the static pressure requirements of modern ductwork.

Key Benefits

• Exact OEM Compatibility: Designed specifically for Carrier corporation equipment, eliminating the mounting and wiring headaches often found with universal "will-fit" motors.
• Multi-Speed Versatility: The 4-speed design allows for precise CFM adjustments to match the climate control needs of your specific furnace or air handler.
• Thermal Protection: Features internal thermal overload protection to prevent winding burnout during high-demand cycles or restricted airflow conditions.
• High Torque Performance: Delivers consistent 1075 RPM performance under load, ensuring optimal heat exchange across the coil or heat exchanger.

Common Questions

What capacitor is required for the HC45AE116?
This motor typically requires a 12.5 MFD / 370V run capacitor. Always verify the rating on the motor nameplate before installation, as using an incorrectly sized capacitor can lead to premature failure.

Is this a direct replacement for my existing 3/4 HP motor?
The HC45AE116 is a direct replacement for specific Carrier/Bryant part numbers. You should verify the frame size (NEMA 48), shaft diameter (1/2 inch), and voltage (115V) to ensure a perfect mechanical fit.

Can I use this motor if my current blower only uses two speeds?
Yes. While this is a 4-speed motor, you can select the most appropriate speed leads for your system's "Cool" and "Heat" taps and cap off the unused leads according to the provided wiring diagram.
