Trane MOT18986 Motor

Contractors know that field reliability depends on precise OEM matches. The Trane MOT18986 Motor is a high-performance 1/2 HP 208-230V 1100 RPM motor designed specifically for demanding HVACR applications. Operating on a 48Y frame with an open air over (OAO) enclosure, this unit maintains thermal stability during continuous operation. As a 4-speed motor, the MOT18986 offers technical flexibility for multi-stage systems, ensuring accurate airflow and high-static performance. The 5.81-inch motor length and belly band mounting provide a drop-in solution for Trane condenser fan motor or blower assembly replacements. Engineered for CW/CCW reversible rotation, this 1-phase PSC motor minimizes shop stock while meeting strict OEM HVAC replacement part specifications. When your job requires a resilient, 1100 RPM 230V motor that withstands high-ambient conditions, the MOT18986 delivers the mechanical torque and electrical efficiency expected by veteran technicians.

• Multi-Speed Versatility: Features a 4-speed design to accommodate various system CFM requirements and residential duct configurations.
• OEM Fitment: Built to 48Y frame standards, ensuring exact physical alignment with 5.6-inch diameter mounting brackets and belly bands.
• Optimized Cooling: The Open Air Over (OAO) design utilizes system airflow to dissipate heat, extending the service life of internal windings.
• Configurable Rotation: Reversible rotation (CW/CCW) allows for broad compatibility across different blower and fan blade pitches.

What is the frame size for the MOT18986?
This motor utilizes a standard 48Y frame (approximately 5.6 inches in diameter), making it a direct fit for most Trane and American Standard air handlers and condenser units.

Can this motor replace a single-speed 1100 RPM unit?
Yes, as a 4-speed motor, you can utilize the high-speed lead for single-speed applications, provided the 1/2 HP and 208-230V specifications match your original equipment.

Does this motor include a run capacitor?
Run capacitors are typically sold separately. Verification of the mfd rating on the motor nameplate is recommended to ensure proper torque and amperage draw.
