Us Motors 1924 Psc Ac Motor 1/2 Hp 115V Teao Yoke Mount

Product Description

The US MOTORS 1924 is a single-phase permanent split capacitor (PSC) AC motor built for HVAC applications. Rated at 1/2 horsepower and 115 volts, this motor operates at 1075 nameplate RPM with two selectable speeds, giving technicians flexibility across a range of airflow requirements. It features a totally enclosed air-over (TEAO) enclosure with a yoke mount configuration and a Frame Size 48YZ footprint. Ball bearings, Class B insulation, and automatic thermal protection make this a durable, serviceable unit suited for installation in condenser fan and evaporator blower assemblies where motor longevity under load is a priority.

This motor is intended for residential and light commercial HVAC systems. The TEAO enclosure is specifically designed for air-over applications where airflow from the system cools the motor exterior. The yoke mount style allows for flexible positioning in condenser units and fan decks. The reversible rotation feature gives the installing technician the ability to match required airflow direction at the time of installation without sourcing a direction-specific unit. Licensed HVAC technicians typically install this motor as a direct replacement or new installation component in ducted and non-ducted air-moving equipment.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect and lock out all power to the unit before removing the existing motor or making any electrical connections. Verify supply voltage matches the 115-volt rating before energizing. Confirm shaft orientation and rotation direction prior to final mounting to avoid rework.
