Trane MOT18979 Motor
The Trane MOT18979 Motor is a high-performance direct drive blower motor designed explicitly for demanding HVAC applications. Operating at 277V 1PH, this 1/2 HP induction motor runs at a fixed speed of 1075 RPM to maintain consistent static pressure and airflow across your evaporator coils. Built with a standard 48Y frame and an Open Air Over (OAO) enclosure, this unit ensures optimal heat dissipation during continuous duty cycles. As a genuine OEM replacement motor, the MOT18979 eliminates the mounting headaches often associated with "universal" motors, featuring the precise shaft diameter and length required for Trane fan assemblies. This motor is the direct factory replacement for legacy part numbers including MOT11204 and MOT11604 (when used with the appropriate kit). For contractors, this means a drop-in installation that maintains the original equipment’s efficiency and performance curves without the need for field modifications or belly band adjustments.
Key Benefits- Precise OEM Compatibility: Direct replacement for MOT18979, MOT11204, and MOT11604, ensuring exact fitment in Trane air handlers and furnaces.
- Efficient Thermal Management: The Open Air Over (OAO) design utilizes the system's own airflow to keep the motor windings cool, extending the service life of the single-phase motor.
- Standardized 48Y Frame: Simplifies the swap-out process with standard mounting dimensions and a consistent 1/2-inch shaft diameter.
- Industrial Voltage Duty: Specifically wound for 277 volt commercial and industrial power supplies, providing stable 1075 RPM output.
- Can I use this to replace a 115V or 230V motor? No. This is a 277V single-phase motor; applying incorrect voltage will lead to immediate winding failure. Always verify your supply voltage on-site.
- Does this motor include the run capacitor? This motor requires a specific MFD-rated capacitor for proper phase shift. We recommend replacing the capacitor whenever installing a new 1075 RPM blower motor.
- Is this motor reversible? This unit is typically set for CCWLE (Counter Clockwise Lead End) rotation. Check your fan blade pitch before installation to ensure proper airflow direction.
Disclaimer: While we strive for 100% accuracy, product data and specifications are subject to change. Please contact our team to confirm compatibility or technical details before purchasing.
