Lennox 12W66 Motor
The Lennox 12W66 motor is a direct-drive OEB style replacement motor engineered for high-static condenser fan applications. Operating at 208-230V single-phase power, this 1/4 HP persistent split capacitor (PSC) motor delivers a steady 825 RPM, making it the standard specification for specific Lennox and Armstrong residential condensing units. Featuring a 48-frame diameter and dual-speed functionality, it allows for precise airflow modulation to maintain head pressure in varying ambient conditions. The motor utilizes an all-angle sleeve bearing system and is designed for TEAO (Totally Enclosed Air Over) operation, ensuring the windings remain protected from environmental debris while relying on the fan blade's airflow for thermal management. When performing a field replacement, ensure the run capacitor is tested and replaced if it falls outside the ±5% tolerance to prevent premature winding failure or overheating. This OEM Lennox part ensures exact physical dimensions for a drop-in installation without bracket modification.
Technical Benefits
- Dual-Speed Versatility: Supports 2-speed operation for optimized efficiency and noise reduction during low-load cycles.
- High Torque Output: Rated at 1/4 HP to handle the static load of heavy-duty condenser fan blades.
- Optimized Heat Dissipation: The TEAO enclosure prevents moisture ingress while facilitating rapid cooling during continuous operation.
- Low Noise Profile: The 825 RPM rating provides a quieter alternative to standard 1075 RPM motors without sacrificing CFM.
Common Questions
What is the frame size and mounting for the Lennox 12W66?
This is a NEMA 48 frame motor, typically mounted via extended thru-bolts or a belly-band bracket depending on the specific cabinet configuration.
Is a new capacitor required for this motor?
Yes, technicians should always match the microfarad (MFD) rating specified on the new motor nameplate to ensure proper phase shift and starting torque.
Can this motor replace a single-speed 825 RPM unit?
Yes, provided the frame size and shaft dimensions match. The high-speed lead is typically used while the low-speed lead is capped, though OEM compatibility should be verified first.
