Century Motors SA1056 Motor

As an HVAC technician, you know that finding a precise match for a blower assembly is critical for maintaining static pressure and system airflow. The Century Motors SA1056 is a professional-grade 1/2 HP PSC motor engineered for multi-speed fan coil and air handler applications. Operating at 208-230V and a nominal 1075 RPM, this 3-speed motor allows for precision tuning of the CFM to meet specific site requirements. Built on a 48Y NEMA frame with a 5-5/8 inch diameter, this double shaft motor features a large 7-1/2" x 1/2" x 7-1/4" flatted shaft configuration, making it the primary F48E66A01 cross reference for legacy equipment. The sleeve bearing design provides quiet operation in residential and light commercial settings, while the semi-enclosed, air-over housing ensures it stays cool during continuous duty cycles. Ensure you have a 7.5 MFD / 370V capacitor on hand, as it is required for proper starting torque and efficiency. With a CCW lead end rotation and automatic thermal overload protection, this motor is a reliable drop-in for technicians handling blower motor replacements.

• Multi-Speed Versatility: Features 3 distinct speed taps to optimize airflow for various air conditioning and heating demands.
• Direct Cross-Compatibility: Functionally identical to F48E66A01, Century 544, and D883, simplifying your truck stock.
• Robust Mechanical Build: The rolled steel frame and semi-enclosed construction are designed for high-ambient temperatures up to 60°C.
• Safety Integrated: Equipped with automatic reset thermal overload protection to prevent winding failure during restricted airflow conditions.

Common Questions

What is the correct capacitor for the SA1056?
This motor requires a 7.5 MFD / 370 VAC run capacitor. Always verify the capacitor's health when installing a new motor to prevent premature failure.

Can I use this to replace a single-shaft motor?
This is a double-shaft motor typically used in fan coil units. While it can technically be used in single-shaft applications if clearances allow, it is designed specifically for dual-blower or shaft-extended configurations.

How do I confirm the rotation?
The SA1056 is rated for Counter Clockwise Lead End (CCWLE) rotation. Always verify the rotation matches your existing blower wheel orientation before final mounting.
