Lennox 81W64 Motor
The Lennox 81W64 is a heavy-duty, 1 HP replacement ECM blower motor specifically designed for high-voltage commercial and industrial HVAC applications. Operating at 460V single-phase with a rated speed of 1050 RPM, this genuine Lennox OEM motor (Part #81W64, also replaces 604253-03) provides the high-torque performance required for large-scale air handlers and rooftop units. Utilizing advanced Electronically Commutated Motor technology, it offers superior energy efficiency compared to standard induction motors, allowing for precise airflow management and reduced operational overhead. This 460v 1hp 1050rpm motor is engineered for a 48-frame assembly and features CCWLE rotation with a durable ball-bearing design to withstand the continuous-duty cycles of demanding environments. It is a critical component for maintaining system static pressure in compatible Lennox CBA27UHE and CBX27UH series units, ensuring reliable climate control and reduced component wear.
Key Benefits:- High-Efficiency ECM Technology: Significant energy savings over PSC motors through better modulation and lower heat dissipation.
- Industrial Grade 460V Support: Specifically rated for 460V1ph systems, eliminating the need for step-down transformers in commercial air handlers.
- OEM Precision Fit: Ensures perfect alignment with the existing Lennox 81W64 Blower Motor housing and wiring harnesses to prevent vibration-induced failure.
- Variable Speed Capability: Compatible with integrated Lennox controls to maintain constant torque across varying static pressure levels.
- Can I replace a standard PSC motor with the 81W64 ECM? This is a programmed OEM replacement motor meant specifically for units designed for ECM communication. Converting a standard motor to this requires the compatible Lennox control board and wiring configuration.
- What causes premature failure in these 460V motors? Standard troubleshooting suggests checking for unbalanced blower wheels or high static pressure, which can lead to module overheating. Ensure the 1050 RPM rating matches your system's design original specs.
- Does it include the control module? Yes, the Lennox 81W64 is a complete motor and module assembly, calibrated for immediate integration into supported air delivery systems.
