Us Motors USMOTOR-3737H Condenser Fan Motor 1/3 Hp 460V

Product Description

The US MOTORS USMOTOR-3737H is a single-phase condenser fan motor designed for outdoor HVAC condensing unit applications. Rated at 1/3 hp and 460 volts, it operates at 1075 RPM on a 6-pole design, making it well suited for moving air across condenser coils in commercial and residential equipment. The totally enclosed air over (TEAO) enclosure protects internal windings from outdoor contaminants while relying on the airstream across the coil for cooling. Class F insulation supports continuous-duty operation in demanding thermal environments. Licensed HVAC technicians handle the selection and installation of this motor type.

This motor fits condensing unit applications where a 48Y frame, stud-mounted, single-speed motor is specified. It runs on 460 VAC single-phase power at 60 Hz and draws 1.3 amps at full load. The reversible rotation allows the technician to configure airflow direction to match the equipment layout. Ball bearings support the 0.5-inch diameter by 6-inch long shaft, providing reliable operation under continuous-duty cycling typical of outdoor condensing units in HVAC systems.

Key Features

• Totally Enclosed Air Over (TEAO) enclosure rated for outdoor condenser service
• Reversible rotation for flexible airflow configuration at installation
• Ball bearing construction for extended service life under continuous-duty load
• Class F insulation rated for high-temperature continuous operation
• Stud mounting compatible with standard 48Y frame condenser unit mounting arrangements
• Single-speed, 6-pole design delivers consistent 1075 RPM output at 60 Hz

Compatibility

Designed as an OEM-style replacement for condenser fan motors requiring a 48Y frame, stud mount, 460 VAC single-phase, 1/3 hp, 1075 RPM specification in residential or light commercial HVAC condensing units.

Installation Notes

Installation and replacement of condenser fan motors should be performed by a licensed HVAC technician. Disconnect and lock out all electrical power to the condensing unit before removing the existing motor or handling wiring. Confirm shaft length, diameter, rotation direction, and mounting configuration match the original equipment specification before securing the motor. Follow NEC requirements and local codes for single-phase motor wiring and equipment grounding.
