Trane MOT18668 Motor

The Trane MOT18668 Motor is a precision-engineered 1/3 HP condenser fan motor designed for high-voltage industrial and commercial HVAC applications. Operating at 460V with a rated speed of 1115 RPM, this 48 frame motor provides the reliable torque necessary for consistent airflow in demanding environments. As a direct OEM replacement motor for the legacy MOT10338, it ensures seamless physical fitment and electrical compatibility with Trane and American Standard rooftop units. The motor features a counterclockwise (CCW) rotation and a single-phase, 60Hz configuration. When performing a swap from the older 10338 model, a new capacitor (typically 7.5 MFD/370V) is often required to maintain optimal starting torque and efficiency. This HVAC replacement part is built with a robust internal winding structure to handle the thermal loads of continuous-duty air-over (TEAO) applications, ensuring long-term stability and peak system performance for service contractors.

• Direct OEM Compatibility: Engineered as the exact substitute for MOT10338, eliminating the need for mounting modifications or bracket adjustments.
• High-Voltage Efficiency: Optimized for 460V 3-phase systems (motor itself is 1 Ph) to provide stable 1/3 HP output in commercial settings.
• Optimal Airflow: The 1115 RPM speed rating ensures correct static pressure and heat exchange rates within the condenser coil.
• Durable Construction: Features a standard 48 frame diameter to fit most factory motor mounts and fan blade hubs.

• Is a new capacitor necessary for installation? Yes, when replacing the MOT10338 with the MOT18668, using a fresh 7.5 MFD/370V capacitor is highly recommended to protect the new windings.
• What is the rotation direction? This unit is Counterclockwise (CCW) lead-end, which is standard for many Trane condenser fan assemblies.
• Can this be used in residential 230V systems? No, this is a 460V motor specifically designed for higher voltage commercial power supplies.
