US Motors 1874 K55HXSRD-4515 Condenser Fan Motor 208/230V 825RPM 48Y 1/4–1/8HP TENV

Condition: New; run capacitor not supplied (requires 5µF 370VAC). This US Motors / Nidec condenser fan motor is a dedicated outdoor-unit motor designed to drive a condenser fan blade in air-over applications (typical split-system AC or heat pump condensing sections). It’s a single-phase, 208/230VAC, 60Hz motor with a 48Y frame and stud mounting, built with a TENV enclosure and thermal protection for reliable long-season operation. Rotation is reversible via lead interchange, making it a practical service replacement when OEM rotation requirements vary by unit. Key Specifications (from nameplate/box) Manufacturer / Brand: US Motors (Nidec Motor Corporation) Catalog / Part No.: 1874 Model: K55HXSRD-4515 Type: Condenser fan motor (air-over) Horsepower: 1/4 – 1/8 HP Voltage: 208/230 VAC Frequency: 60 Hz Phase: 1 Speed: 825 RPM Current: 2.0 A Frame: 48Y Enclosure: TENV (Totally Enclosed Non-Ventilated) Motor protection: Thermally Protected Mounting: Stud mount Bearing (label shows): “SAB” (commonly indicates sleeve/bearing style in many HVAC motors—verify if your application demands ball bearings) Ambient rating (label): 60°C Required run capacitor: 5.0 µF, 370 VAC (not included) Rotation (as marked): CCW Lead End (reversible) Motor Shaft Rotation (requested format): CWSE/CCWLE (because it’s CCW when viewed from the lead end; opposite when viewed from the shaft end) Wiring / Rotation Notes (service-friendly) Typical 208–230V connections: Black = L1, White = L2 (per diagram on motor label) Capacitor leads: Brown and Brown/White stripe to 5µF 370VAC run capacitor To reverse rotation: interchange ORG and YEL leads (per label instruction) Features Designed for condenser duty (air-over): optimized for outdoor fan sections Reversible rotation via simple lead swap (useful across multiple OEM designs) Thermally protected for overload resilience TENV enclosure helps keep windings sealed from direct airflow contaminants 48Y frame compatibility with many HVAC condenser motor mounts and fan hubs Stud mounting for fast drop-in replacement on many top-grille and bracket setups Uses a common, economical capacitor value (5µF 370VAC) Applications and Spheres of Use Residential and light commercial AC condensing units Heat pump outdoor sections HVAC condenser fan blade drive (air-over condenser compartment) Service replacement motor for OEM condenser fan assemblies Cross-Referenced Models (as shown on box) Organized list of identifiers and stated “use for” references: US Motors 1874 K55HXSRD-4515 S39-127 MOT06039 98N02 Comparable Products (similar class/service replacement) When matching, prioritize frame (48Y), RPM (825), HP range, voltage, capacitor (5µF), mounting style, and rotation needs.
