Trane MOT18974 Motor
The Trane MOT18974 Motor is a high-performance 1/20 HP blower motor engineered for specific Trane and American Standard air handlers and light commercial fan assemblies. Operating on a standard 115V single-phase power supply, this 1050 RPM unit features a 3-speed configuration (Low, Med, High), allowing contractors to fine-tune airflow delivery based on static pressure requirements and system demand. Designed with a 42-frame rolled steel body and an open air-over (OAO) enclosure, the MOT18974 ensures efficient thermal management by utilizing the airstream to cool the motor windings during continuous operation.
For technicians performing a field replacement, the MOT18974 is a direct OEM replacement motor that simplifies installation with its resilient base or bracket-mount compatibility. It typically requires a 5 MFD / 370V run capacitor (verify rating on current motor nameplate) to maintain proper torque and 1050 RPM nominal speed. This motor is frequently utilized in Trane furnace inducer assemblies or small evaporator blowers where multi-speed versatility and a compact 0.05 HP footprint are required for space-constrained housings. Utilizing genuine Trane parts like the MOT18974 ensures precise shaft alignment and electrical matching, preventing the premature bearing wear often seen with universal aftermarket alternatives.
Key Benefits- Multi-Speed Versatility: The 3-speed 1050 RPM design allows for precise CFM adjustments to meet residential comfort levels.
- Reliable 115V Operation: Compatible with standard 115-volt circuits, drawing approximately 0.6 Amps for energy-efficient performance.
- OEM Precision: Genuine MOT18974 specifications guarantee a proper fit in 42Y frame mounts without the need for field modifications.
- Thermal Protection: Includes internal automatic reset thermal overload protection to prevent winding failure during high-static conditions.
Is this motor reversible?
The Trane MOT18974 is typically set for CCW (Counter-Clockwise) rotation from the lead end, though some 42-frame variations allow for wiring adjustments. Always verify the rotation of the existing blower wheel before securing the motor.
Does the MOT18974 include a new capacitor?
Most OEM Trane motors are sold as the motor only. It is professional best practice to replace the 5 MFD run capacitor simultaneously to ensure the new 1/20 HP motor starts under the correct load.
Can I use this to replace a single-speed motor?
Yes, provided the 1/20 HP, 115V, and frame size match. The 3-speed leads allow you to choose the optimal tap for your specific ductwork layout.
