Lennox 12Y16 Motor

The Lennox 12Y16 Motor is a heavy-duty, 3 HP induction motor engineered for demanding commercial HVACR applications. Operating on 208-230V, three-phase power, this unit delivers a consistent 1740 RPM for high-torque performance in air handling units and condenser systems. It features a specialized 56YZ frame, ensuring a precise match for specific mounting configurations found in mid-to-large-scale Lennox equipment. As a direct replacement for Lennox 79W65, this motor facilitates a rapid swap-out, reducing labor hours and downtime. The TEFC (Totally Enclosed Fan Cooled) design protects internal components from airborne debris and moisture, maintaining thermal stability under continuous operation. This commercial blower motor is built with high-grade insulation to handle the voltage fluctuations common in industrial environments, making it a reliable choice for HVAC motor replacement projects requiring OEM-spec performance and longevity.

Key Benefits

• Direct OEM Fit: Drop-in replacement for the 79W65 motor, eliminating the need for mounting bracket modifications.
• Industrial Durability: The 3-phase configuration provides superior efficiency and starting torque compared to single-phase alternatives.
• Reliable Speed: 1740 RPM output ensures optimal airflow and static pressure for large-tonnage commercial systems.
• Robust Construction: Precision-balanced rotor and high-quality bearings minimize vibration and mechanical wear.

Common Questions
