Trane MOT18904 Motor

The Trane MOT18904 Motor is a critical OEM replacement motor designed for high-static air handling and furnace applications. As a direct drop-in for the MOT5065, this 1/15HP HVAC motor operates on a 200-230V single-phase circuit, delivering a consistent 1650 RPM for optimal airflow. Built on a standard NEMA 48 frame, it features a TEAO (Totally Enclosed Air Over) enclosure, ensuring the internal windings remain protected from dust and moisture in the airstream. This motor utilizes a permanent split capacitor (PSC) design, requiring a 5.0 MFD / 370V capacitor for reliable startup and performance. With a CCWLE (Counter Clockwise Lead End) rotation and a 1/2-inch diameter shaft, it maintains precise compatibility with factory-specified blower wheels and fan blades. When replacing a failed Trane induction motor, verifying the frame size and voltage is essential for maintaining system static pressure and energy efficiency.

• Direct OEM Compatibility: Engineered as the exact replacement for MOT5065, eliminating the need for mounting modifications or bracket adjustments.
• Industrial-Grade Enclosure: The TEAO enclosure prevents particulate ingress, extending the service life of the 1650 RPM blower motor in challenging environments.
• Standardized Mounting: The 48 frame motor design ensures a high-tolerance fit within existing Trane and American Standard air handlers.
• Thermal Efficiency: Optimized for 200-230V operation, reducing amp draw and heat buildup during extended run cycles.

Is the MOT18904 a compatible replacement for older MOT5065 units?
Yes, the MOT18904 is the manufacturer-designated direct replacement for the MOT5065. It matches the electrical specifications, frame size, and rotational direction required for a seamless swap.

What capacitor should be used with this motor?
This motor requires a 5.0 MFD / 370V AC capacitor. It is a best practice for technicians to replace the capacitor during motor installation to ensure the PSC motor starts under proper torque.

Does the rotation on this motor match my existing blower?
The Trane MOT18904 is configured for CCWLE rotation (Counter Clockwise looking at the Lead End). Always verify your existing fan pitch and directional requirements before securing the motor to the housing.
