Century Motors B6507 Motor

When you're spec'ing a direct drive blower motor for single-phase HVAC systems, the Century Motors B6507 is the industry standard for a 5-inch diameter PSC motor. This multi-horsepower unit is engineered to cover 1/5, 1/6, and 1/10 HP requirements at 230V, making it a critical truck-stock item for service calls involving furnace blowers, air handlers, and fan coil units. Running at a nominal 1075 RPM, the B6507 provides 3-speed flexibility with current ratings of 1.3, 0.9, and 0.7 Amps, ensuring you can dial in the precise airflow needed for the specific cabinet static pressure.

The 42Y NEMA frame design features an Open Air Over (OAO) enclosure, which relies on the system's airflow to maintain optimal operating temperatures for the Class B insulation. It utilizes a 1/2" x 5 1/2" flatted shaft and high-grade sleeve bearings designed for continuous duty in residential or light commercial applications. This motor is a drop-in Century B6507 replacement for the B6507V1 and York S1-1468-120P. Since it is a reversible rotation motor, you can easily configure it for clockwise or counter-clockwise operation on-site. Note that a 7.5 MFD / 370V capacitor is required for proper phase shift and torque but is sold separately.

• Versatile Multi-HP Rating: Consolidates inventory by covering 1/5 HP, 1/6 HP, and 1/10 HP applications in a single unit.
• 3-Speed Calibration: Allows for precision airflow adjustments to match the original equipment manufacturer's (OEM) specifications.
• Reversible Rotation: Field-interchangeable CW/CCW rotation viewing the shaft end simplifies installation across different blower housings.
• Rugged Build: Features a rolled steel shell and automatic thermal overload protection to prevent winding failure during high-amperage events.
• Broad Compatibility: Serves as a primary cross-reference for AO Smith, GE, and Dayton 42-frame HVAC motors.

Common Questions

What is the correct capacitor for the B6507 motor?
This motor requires a 7.5 MFD 370 VAC permanent split capacitor (not included) to ensure the correct starting torque and efficient running amperage.

Can this motor be mounted in any orientation?
Yes, the B6507 includes resilient mounting rings and extended studs on the shaft end, supporting all-angle mounting in various blower decks and brackets.

How do I change the rotation of the Century B6507?
The motor features standard reversing leads; simply swap the color-coded connectors as per the wiring diagram on the nameplate to switch between CW and CCW rotation.
