Us Motors k055wms1280012b Condenser Fan Motor 1/4 Hp

Product Description

The US MOTORS k055wms1280012b is a 1/4 HP permanent split capacitor condenser fan motor designed for single-phase HVAC condensing unit applications. Rated at 1075 RPM and 208-230 volts, it operates in a totally enclosed air-over (TEAO) enclosure suited for outdoor condenser fan service. The motor weighs 11.0 pounds, carries a 48Y frame designation, and features automatic reset thermal protection. Full load current draw is 1.5 amps, and the run capacitor is rated at 5 MFD at 370 volts. Licensed HVAC technicians and refrigeration mechanics are the primary installers for this motor type.

This motor is intended for residential and light commercial air conditioning condensing units where a 48Y frame TEAO condenser fan motor is specified. It mounts via stud or band mounting configurations, making it compatible with a range of condenser fan blade and shroud assemblies. The catalog number for this unit is 1860. Rotation is counter-clockwise when viewed from the lead end, reversible as configured. Operating frequency is 60 Hz, and the ambient temperature rating is 60 degrees C, appropriate for rooftop and outdoor ground-level condensing unit installations.

Compatibility

Designed as an OEM-style replacement condenser fan motor for residential and light commercial air conditioning condensing units requiring a 48Y frame, 1/4 HP, 1075 RPM, 208-230V single-phase TEAO motor with stud or band mounting.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect and lock out all electrical power to the condensing unit before removing the existing motor or handling wiring. Confirm run capacitor MFD and voltage ratings match the replacement motor specifications before energizing. Verify blade pitch and shaft engagement per the equipment manufacturer guidelines before restoring power.
