Key Features & Benefits
- Totally Enclosed Air Over enclosure protects internal components from dust, debris, and moisture in outdoor or harsh environments
- Self-aligning ball bearings compensate for minor shaft misalignment, extending motor service life and reducing vibration
- PSC design provides smooth, efficient starting and running performance without a start capacitor relay
- Low 850 RPM operating speed is ideal for low-noise, low-velocity fan applications
- 48Y NEMA frame ensures broad cross-reference compatibility with OEM and replacement installations
- Stud mount configuration simplifies installation in condenser fan decks and air-handling equipment
- 1/2″ shaft diameter accommodates standard fan blade hubs and pulleys
Typical Applications
- Condenser fan motors on commercial and residential HVAC equipment
- Evaporator fan motor replacements
- Air-over fan duty applications requiring a TEAO-rated motor
- OEM replacement in systems specifying a 48Y frame stud-mount PSC motor
The US Motors 1743 is a trusted choice for HVAC contractors and technicians seeking a durable, drop-in replacement motor that meets the performance demands of air-over fan duty service.
