The US Motors 5462H is a permanent split capacitor (PSC) condenser fan motor built for continuous-duty operation in commercial and residential HVAC condensing units. With a 5.6" frame, reversible rotation, dual-speed operation, and automatic thermal overload protection, it covers a wide range of condenser fan replacement applications where a reliable, direct-drive motor is needed.
The 5462H is a workhorse replacement motor engineered to meet the demands of outdoor condensing units. Its totally enclosed air-over (TEAO) enclosure shields internal windings from the airstream contaminants common in outdoor HVAC environments -- dust, debris, and moisture. Class B insulation and automatic thermal overload protection keep the motor running safely even during high-ambient summer loads.
With dual-speed operation (two winding speeds), reversible shaft rotation, and a horizontal stud mount, this motor adapts to a range of OEM configurations without modification. The 48-inch lead length provides routing flexibility inside most condenser cabinets.
Also sold and stocked under the NBK Parts number 20587, making cross-referencing straightforward for HVAC technicians and parts distributors.
Shaft rotation direction is field-selectable -- swap lead connections to match CW or CCW fan blade requirements without ordering a separate motor.
Built for uninterrupted operation in demanding outdoor condensing applications, not just intermittent cycling.
Automatic thermal overload cuts power if the motor overheats and resets automatically once it cools -- protecting windings from burnout.
Totally enclosed air-over construction keeps contaminants out of windings while relying on the condenser airstream for cooling -- the correct design for direct-drive fan duty.
The 5462H uses a horizontal stud mount, the standard configuration for most residential and light commercial condenser units. The 5.6" diameter frame (48Y-style) matches the mounting footprint of many OEM condenser fan motors from Carrier, Trane, Lennox, Rheem, and York platforms, though always verify your unit's mounting hole pattern, shaft diameter, and blade pitch before installation.
As a permanent split capacitor (PSC) motor, the 5462H requires an external run capacitor to operate. The correct capacitor value (microfarads and voltage rating) is printed on the motor nameplate. A mismatched or failed capacitor is one of the most common causes of PSC motor failure -- always replace the run capacitor when replacing the motor.
The 5462H is also cataloged and sold as NBK Parts number 20587. When cross-referencing, match the following to your existing motor nameplate to confirm compatibility:
