Nidec-US Motors LX7931 Motor
The Nidec-US Motors LX7931 is a high-performance 1/4 HP condenser fan motor engineered for demanding HVACR applications. As a Permanent Split Capacitor (PSC) motor, it operates at a consistent 825 RPM, providing the reliable airflow necessary for efficient heat exchange in residential and light commercial condensing units. This single-phase, 8-pole motor is designed for 208-230Vac systems, drawing 1.7 Amps at full load. Its Totally Enclosed Air Over (TEAO) enclosure ensures the internal components are protected from environmental debris while relying on the system's airflow for cooling.
Built with a 48Y NEMA frame and featuring a 5.6-inch diameter, the LX7931 is a versatile OEM replacement motor, frequently cross-referenced for Lennox systems (replacing models like 97M5101 and K55HXLTD-0249). The stud mount configuration and counterclockwise lead end (CCWLE) rotation allow for straightforward installation in standard fan housings. For robust mechanical support, it utilizes SAB bearings (Self-Aligning Bearings) or high-grade ball bearings depending on the specific production run, ensuring quiet operation and axial load management.
Key Benefits
- Optimized Airflow: The 825 RPM speed is specifically calibrated for high-static condenser applications, improving overall system SEER ratings.
- Durable Construction: The totally enclosed air over design prevents moisture and dust ingress, extending the motor's service life in outdoor environments.
- Broad Compatibility: Serving as a direct Lennox replacement motor, it fits several 48-frame stud-mounted fan assemblies without modification.
- Electrical Efficiency: Operating at 208-230V with a low 1.7 Amp draw, it reduces energy consumption and heat generation during continuous duty.
Common Questions
What is the correct rotation for the LX7931?
This motor is rated for CCW Lead End (CCWLE) rotation. Always verify the fan blade pitch before installation to ensure proper airflow direction.
Does this motor include the run capacitor?
Most technician-grade Nidec LX7931 motors require a 5 MFD or 10 MFD 370V capacitor (check nameplate for specific requirements). While some kits include it, we recommend having a fresh capacitor on hand for every motor change-out to ensure peak performance.
Can I use this motor to replace a 1075 RPM motor?
No, replacing a 1075 RPM motor with an 825 RPM motor will significantly reduce airflow, potentially leading to high head pressure and compressor failure. Always match the original RPM specs.
