Trane MOT10343 Motor

The Trane MOT10343 Motor is a high-performance, 9/10 HP blower motor engineered for heavy-duty HVAC applications within commercial and light industrial environments. Operating at 208-230V and a fixed speed of 1075 RPM, this 48 Frame motor provides the high-torque output required for demanding air handler and furnace blower assemblies. As a genuine Trane OEM replacement motor, it ensures seamless physical fitment and electrical compatibility, eliminating the air volume delivery issues often found with generic substitutes. This unit utilizes a permanent split capacitor (PSC) design and is rated for 60Hz single-phase operation, featuring high-grade ball bearings for sustained axial and radial load management. Whether used in a rooftop unit or a centralized furnace, the MOT10343 HVAC motor maintains system static pressure and optimal thermal transfer across the evaporator or heat exchanger. Utilizing this original equipment manufacturer part ensures the system operates within calibrated Locked Rotor Amp (LRA) and Full Load Amp (FLA) specifications to prevent nuisance tripping and control board damage.

• Precision Airflow Management: The 1075 RPM speed is calibrated for specific Trane blower wheels to maintain design-spec CFM.
• Industrial-Grade Construction: Features a 48 Frame housing and dual ball bearings for high-duty cycle reliability in commercial settings.
• Simplified Drop-in Fit: As an OEM Trane MOT10343, mounting holes and shaft diameter align perfectly with factory fan housings.
• Optimized Electrical Efficiency: Designed for 208-230V single-phase systems, requiring a 15 MFD at 370V capacitor for peak performance.

What is the correct capacitor for the Trane MOT10343?
This Trane 9/10 HP motor requires a 15 MFD / 370V run capacitor. Always replace the capacitor when installing a new motor to prevent premature winding failure.

Can this motor be used in both 208V and 230V systems?
Yes, the MOT10343 is rated for 208-230V operation, making it suitable for standard residential and commercial three-phase tapped single-phase applications.

Is the rotation reversible on this 48 Frame motor?
The Trane MOT10343 is typically manufactured for Clockwise Opposite Shaft End (CWOSE) rotation. Verify your specific blower wheel orientation before concluding the installation.
