Design & Construction
The Totally Enclosed Air Over (TEAO) enclosure protects internal windings from dust, debris, and moisture — making this motor well-suited for outdoor condenser applications where the motor is cooled by the airstream it drives. The 48Y frame ensures broad cross-compatibility with standard OEM mounting configurations, while the extended stud, footless design simplifies direct-drive condenser fan installations.
Performance & Reliability
Operating at 1075 RPM, the X459 delivers the low-speed torque characteristics ideal for condenser fan blade operation, helping maintain proper system static pressure and heat rejection. At 2.1 amps full load draw on a 460 Vac single-phase supply, this motor is well-matched for commercial condensing units and rooftop equipment.
