Trane MOT18831 Motor
The Trane MOT18831 Motor is a high-performance 1/3HP condenser fan motor designed for heavy-duty HVACR applications. Operating on a 208-230V single-phase circuit, this 1075 RPM induction motor provides stable torque and consistent airflow for critical cooling stages. Built with a 48-frame (5-5/8 inch diameter) rolled steel housing and aluminum flange, it offers professional-grade corrosion resistance and structural integrity in demanding outdoor environments. This direct-drive motor is engineered for high-static efficiency, ensuring compatibility with Trane and American Standard rooftop units or residential split systems. As an OEM replacement motor, it maintains factory-spec performance, reducing vibration and noise levels compared to generic alternatives.
Key Benefits for Contractors:- OEM Compatibility: Exact drop-in fit for Trane MOT18831, eliminating the need for shaft modifications or bracket field-engineering.
- Durable Construction: Features a rolled steel frame and aluminum end shields for superior heat dissipation and environmental protection.
- Efficient Performance: Designed as a 1/3 HP 1075 RPM motor to maintain original system SEER ratings and airflow dynamics.
- Versatile Mounting: Standard 48-frame motor configuration supports belly-band or stud mounting for rapid installation.
What capacitor is required for the MOT18831?
This motor typically requires a run capacitor (check the nameplate for specific MFD rating, usually 5 or 7.5 MFD at 370V/440V) to ensure proper starting torque and amp draw.
Can this motor replace a 1/4 HP or 1/2 HP unit?
Always match the horsepower (1/3 HP) and RPM (1075) of the original motor. Using an underrated motor will lead to overheating, while an overrated motor may cause excessive noise and static pressure issues.
Is this a reversible motor?
While many 48-frame HVAC motors are electrically reversible, always verify the lead wire configuration or rotation arrow on the housing to match the original CW or CCW discharge.
