Century Motors D1056 Motor

The Century Motors D1056 is a professional-grade 1/2 HP direct drive blower motor designed for high-performance indoor air handling units. Featuring a Permanent Split Capacitor (PSC) design, this 48-frame motor operates at a 1075 RPM nominal speed across three distinct speed taps, allowing for precise airflow adjustment in various HVAC/R configurations. This unit is engineered with an Open Air Over (OAO) enclosure and sleeve bearings to facilitate continuous duty in the airstream, ensuring reliable thermal management and longevity. With a 5-5/8 inch diameter and 2 1/4 inch resilient rings (including 2 1/2 inch adapters), it functions as a universal replacement motor for numerous OEM applications.

Operating on 208-230V single-phase power at 60 Hz, the D1056 is the direct replacement for 5KCP39NGN656 and common GE/Genteq 3588 series models. The lead reversible rotation and 26-inch lead wires provide maximum installation flexibility for contractors in the field. To ensure system safety, the motor is equipped with an automatic overload protector and Class B insulation rated for a 40°C ambient temperature. For optimal startup and running efficiency, a 7.5 MFD / 370V capacitor is required (sold separately).

• Universal Compatibility: Serves as a versatile 1/2 HP HVAC motor for various fan coil and blower assemblies.
• 3-Speed Versatility: Multiple speed taps (3.2-4.3 Amps) allow for customized CFM delivery to meet specific system requirements.
• Reliable Protection: Integrated auto protector prevents thermal damage during high-load conditions or restricted airflow.
• Flexible Mounting: Includes resilient rings and adapters to fit standard 5-5/8 inch motor brackets and housings.
• Field Reversible: Simple lead reversal adapts the unit to either CW or CCW rotation requirements instantly.

Common Questions

What capacitor does the D1056 require?
This motor requires a 7.5 MFD / 370 VAC run capacitor to operate at the correct electrical efficiency and torque specifications.

Can this motor replace a 115V blower motor?
No, the D1056 is designed strictly for 208-230V AC applications. Using this on a 115V circuit will result in failure and potential equipment damage.

Is this a suitable replacement for GE 5KCP39NGN656?
Yes, the D1056 is a direct technical cross-reference for the 5KCP39NGN656 and many other 48-frame blower motors.
