Century Motors OYK1028 Motor

The Century Motors OYK1028 is a professional-grade 1/4 HP condenser fan motor designed for high-reliability service in HVACR systems. Operating at 208-230 Vac, this permanent split capacitor (PSC) motor delivers a steady 850 RPM at a single speed, drawing 1.4 Amps. Built on a standard 48Y Nema frame with a 5.6-inch diameter, it features a totally enclosed air over (TEAO) design to protect internal windings from environmental debris. The 1/2" x 3 1/8" shaft with a flat provides a secure fit for fan blades, while the sleeve bearing system ensures quiet operation in vertical shaft-down or horizontal orientations. This OEM replacement motor is a direct drop-in for several A.O. Smith, Dayton, and York models, making it a versatile choice for condenser fan motor replacement. For optimal installation, verify your lead end rotation requirements, as this unit is configured for CW lead end rotation and requires a 5 MFD / 370V capacitor.

• Enhanced Durability: The TEAO enclosure and rolled steel construction prevent dust and moisture ingress, extending the life of the single phase motor.
• Broad Compatibility: Serves as a cross-reference for various 48-frame motors, including York S1-024-25119-000 and A.O. Smith F48A46A01.
• Quiet Performance: Engineered with precision sleeve bearings to reduce vibration and noise during high-demand cooling cycles.
• Integral Protection: Features automatic thermal overload protection to prevent winding failure during high-ambient 40°C operating conditions.

What capacitor is required for the OYK1028?
This motor requires a 5 MFD / 370V capacitor. Always check the microfarad rating of your existing capacitor, as using an incorrect size can lead to premature motor failure.

Is this a direct replacement for York condenser motors?
Yes, the OYK1028 is frequently used as a York replacement motor. Contractors should verify the 1/2-inch shaft diameter and the 8-pole, 850 RPM specification before installation.

Can this motor be mounted in any orientation?
While typically used in vertical shaft down applications with extended studs, the TEAO design and bearing configuration support standard condenser fan mounting brackets.
