Trane MOT18994 Motor

The Trane MOT18994 Motor is a high-performance 1/8 HP HVAC motor designed for demanding air-moving applications in residential and light commercial units. Operating on 120V single-phase power, this permanent split capacitor (PSC) motor features a 3-speed configuration—1050, 900, and 700 RPM—allowing for precise airflow adjustment in blower assemblies and evaporator fan systems. Built on a 48 frame with an Open Air Over (OAO) enclosure, it utilizes a rolled steel frame and aluminum flange to provide superior heat dissipation and structural integrity during continuous operation. With a 3.81-inch motor length and standard belly band mounting, this OEM replacement motor is engineered for a drop-in fit in tight service clearances. The 0.5-inch diameter shaft extends 6.5 inches to accommodate various blower wheel depths, ensuring broad Trane compatibility for field technicians. For multi-speed furnace or air handler repairs, this motor delivers the high starting torque and efficient performance required to restore system static pressure.

• Multi-Speed Flexibility: Features 1050/900/700 RPM tap settings for optimized airflow regardless of ductwork resistance.
• Reliable PSC Design: Permanent split capacitor architecture provides high starting torque with low running amperage.
• Industrial-Grade Build: Rolled steel housing and OAO enclosure ensure the MOT18994 maintains cooling while operating in the airstream.
• Technician-Ready Fit: Standard 48 frame and belly band mounting simplify the replacement of worn-out 1/8 HP 120V motors.

Is the MOT18994 motor reversible?
Yes, this motor supports CW/CCW rotation settings, making it a versatile Trane replacement part for different blower configurations.

What capacitor is required for this motor?
A run capacitor is required for operation; always match the microfarad (MFD) rating specified on the MOT18994 nameplate for optimal torque.

Can I use this motor in an enclosed cabinet?
This is an OAO (Open Air Over) motor, meaning it requires the ambient air from the fan or blower it is driving to maintain proper operating temperature.
