Trane MOT18678 Motor

The Trane MOT18678 Motor is a high-performance, single-phase condenser fan motor engineered for commercial and industrial HVAC system repair. Operating at 460V and delivering 1/5 HP at a rated speed of 1115 RPM (or approximately 1075-1080 RPM depending on load conditions), this motor is a drop-in OEM replacement part for critical equipment uptime. Built within a standard 48 frame, it features a Totally Enclosed Air-Over (TEAO) enclosure to protect internal components from moisture and airborne debris commonly found in outdoor condenser environments. The motor utilizes a CCW / LE rotation (Counter-Clockwise Lead End) and is designed for any-position mounting, typically secured via belly band or rear-end mounting holes. Technical parameters include a 0.5-inch shaft diameter with a 2.92-inch length, requiring a 7.5 MFD/370V capacitor for proper HVAC troubleshooting and performance. Relying on genuine Trane parts ensures precise electrical compatibility and mechanical fit, maintaining the airflow efficiency of your air handler or condensing unit.

Key Benefits:

• Optimized Performance: Specifically wound for 460v 1ph 1/5hp 1115rpm motor applications to ensure factory-spec air volume.
• Durable Construction: The TEAO enclosure and internal thermal protection prevent premature failure in high-demand environments.
• Broad Compatibility: Standard 48-frame sizing with flexible mounting options simplifies the swap-out process for field technicians.
• OEM Reliability: Built by Trane, ensuring the motor meets strict HVAC equipment engineering standards for starting torque and load management.

Common Questions:

• Is this motor compatible with 208/230V systems? No, this is a dedicated 460V motor; using it with lower voltages will result in failure to start or winding damage.
• What is the required capacitor for the MOT18678? For stable operation, a 7.5 MFD / 370V AC capacitor must be used.
• Can I change the rotation of this motor? This unit is set for CCW / LE rotation; verify your fan blade pitch before installation to ensure proper airflow direction.
