A genuine Emerson (Regal/Genteq family) K55-series permanent split capacitor (PSC) condenser fan motor used in residential and light-commercial outdoor condensing units. This build—K55HXKPT-9738—is a 1/8 HP, 208–230 V, single-phase motor with 48Y frame and air-over, continuous duty design (TEAO style for condenser airflow cooling). It’s specified by Allied Air Enterprises under R47477-001 / 47477 and commonly drops in where an OEM 1/8 HP 230 V Allied/Armstrong/Ducane/Concord** condenser fan motor is called out. Reuse your belly-band mount and fan blade; match nameplate RPM and capacitor value before energizing.

On-motor markings (provided): Emerson Model K55HXKPT-9738, HP 1/8, Volt 208–230, MFG No C07C, INS CL B, air over cont, Frame 48Y.

Features

• PSC condenser fan motor for outdoor units; engineered for air-over continuous duty

• 1/8 HP, 208–230 VAC, 1-phase; standard HVAC replacement class

• Frame 48Y cylindrical body for belly-band mounting (reuse existing strap)

• Class B insulation for typical condenser ambient conditions

• OEM cross: Allied Air R47477-001 / 47477 (see Cross-Refs)

• Field-reversible rotation (wire per diagram to match blade airflow)

• Designed for use with a run capacitor (typical for this model family: 5 µF / 370 VAC—confirm your nameplate)

Applications / Spheres of Application

• Residential split-system A/C condensers (Allied Air family brands such as Armstrong Air, Ducane, Concord, AirEase, etc.; verify by part list)

• Light commercial package units calling for 1/8 HP, 208–230 V condenser fans

• Service stock for HVAC contractors needing an OEM-spec Allied Air swap

Motor Specifications (as labeled / typical for this build)

• Manufacturer/Brand: Emerson (Regal/Genteq family)

• Model: K55HXKPT-9738

• Horsepower: 1/8 HP

• Voltage: 208–230 VAC, Single-phase, 60 Hz

• Enclosure/Duty: Air-over, continuous duty (TEAO style; relies on condenser airflow)

• Insulation Class: B

• Frame: 48Y (belly-band mount)

• Rotation: Reversible (report direction as CCWSE/CWLE; set by lead wiring)

• Run Capacitor: 5 µF / 370 VAC typical for this Emerson build (verify on your motor label)

• Nameplate Amps / RPM: Not shown on provided markings; K55 1/8 HP outdoor motors are commonly 825 or 1075 RPM and ~0.7–1.0 A. Confirm on your nameplate or OEM spec before install.

• Country of Origin: Mexico (per Allied/Genteq manufacturing)

Installation Notes (HVAC tech essentials)

• Match the capacitor value/voltage to the motor nameplate. A 440 VAC-rated cap is acceptable replacement for 370 VAC.

• Verify RPM against the original motor. RPM mismatch changes condenser CFM and head pressure.

• Set blade depth & pitch per OEM shroud spec; tighten hub on clean shaft flats.

• Mounting: Reuse belly-band; orient weep/drain features down; secure leads away from blade.

• Rotation: Briefly bump run to verify airflow; swap designated leads to reverse if needed (see wiring tag).

Part of Larger Systems

• Outdoor condensing sections of Allied Air brands (Armstrong Air, Ducane, Concord, Airease, etc.) using OEM R47477-001 motors in the 1/8 HP class.
