A dependable direct-replacement condenser fan motor engineered to swap into Fasco, GE, and a wide range of compatible OEM applications. The 9723 is a permanent split capacitor (PSC) motor with ball bearings, automatic overload protection, and a totally enclosed air-over (TEAO) design built to handle the demanding thermal environment of condenser duty. Also catalogued as NBK Parts 20222.
When your condenser fan motor fails, the refrigerant-side of your system stops rejecting heat and the whole unit shuts down. The New Century 9723 is purpose-built for condenser fan service: it runs at 1075 RPM, accepts 208-230V single-phase power at 60 Hz, and is rated for ambient temperatures up to 140 deg F (60 deg C) -- the kind of punishment a rooftop or outdoor condenser sees on a hot summer day.
The permanent split capacitor design delivers smooth, efficient starting and running without the added complexity of a start capacitor relay. Class B insulation and automatic thermal overload protection mean the motor will trip and protect itself before winding damage occurs if airflow is obstructed or the unit is over-cycled.
Ball bearings on both ends support the shaft under the side-load conditions typical of belt or blade-direct condenser fans, extending service life versus sleeve-bearing alternatives.
Built-in thermal overload trips the motor before winding damage occurs during blocked-airflow or over-temperature events, then resets automatically once cooled.
The TEAO enclosure keeps contaminants out of the motor windings while relying on the condenser airstream for external cooling -- the correct rating for outdoor condenser service.
Rated 1/4, 1/5, and 1/6 HP, giving technicians flexibility to cross-reference and replace motors across several OEM horsepower ratings with a single stocked part.
The 9723 uses a permanent split capacitor (PSC) circuit, also called a capacitor-run motor. This design runs a run capacitor continuously in the auxiliary winding, providing good efficiency and quiet operation. Note: a run capacitor is required for operation and is not included with the motor -- match the capacitor value to the original OEM specification or the motor nameplate when ordering a replacement capacitor.
The 1/2" diameter shaft has a flat milled for secure set-screw retention of fan blades. The 3" shaft extension provides adequate engagement length for most standard condenser fan blade hubs. Extended stud mounting on the motor face allows it to bolt into the same footprint as the original Fasco and GE motors it replaces.
Factory-installed 36" color-coded leads give installers enough slack to reach the control board or terminal block without splicing in most rooftop and split-system condenser applications. Leads exit through a standard grommet; use appropriately rated wire nuts or terminal connectors rated for outdoor/wet locations.
The New Century 9723 is designed to replace motors in a broad range of equipment from Fasco, GE, and other manufacturers that share the 5" frame, 1075 RPM, 208-230V, PSC specification. Always verify the replacement against the original motor's nameplate -- key parameters to match are: voltage, full-load amps, RPM, HP, frame diameter, shaft diameter, shaft extension length, and mounting style.
