Lennox 25W65 Motor
The Lennox 25W65 is a high-performance direct drive blower motor specifically engineered for demanding commercial HVACR applications. Operating at 575V with a 1/4 HP output, this PSC motor is designed for high-efficiency airflow management in Lennox heating and cooling units. Running at a nominal 825 RPM, it provides the precise torque required for consistent static pressure across the evaporator or condenser coil. For the field technician, this motor features a standard 48-frame diameter and uses a 6-pole configuration to maintain low noise levels while maximizing mechanical longevity. During installation, verify that your run capacitor values match the original equipment manufacturer (OEM) requirements to prevent premature winding failure. This HVAC replacement motor ensures seamless integration with existing drive assemblies and control systems, maintaining the factory-specified performance curve of the air handler.
- Industrial-Grade Ratings: Optimized for 575-volt three-phase or high-voltage single-phase configurations common in large-scale commercial facilities.
- Sleeve Bearing System: Utilizes high-durability sleeve bearings for smooth, continuous operation in standard thermal environments.
- OEM Compatibility: Exact-fit Lennox OEM motor replacement ensures proper shaft diameter, length, and rotation without field modifications.
- Thermal Protection: Features internal automatic reset thermal overload protection to safeguard the motor under high-load conditions.
Common Troubleshooting Questions
What is the frame size of the Lennox 25W65 motor?
This motor utilizes a standard 48-frame size, making it compatible with most Lennox mounting brackets and belly-band kits designed for 5.6-inch diameter motors.
Can I use an 1100 RPM motor to replace this 825 RPM model?
No. Replacing an 825 RPM blower motor with a higher-speed motor will increase the amperage draw beyond the rated limit, likely tripping the breaker or damaging the fan wheel.
Does this motor require a specific capacitor?
Yes, checking the MFD rating on the motor nameplate is critical. Using an incorrectly sized capacitor will decrease torque and lead to motor overheating.
