Trane MOT18623 Motor

Trane

The Trane MOT18623 Motor is an essential direct replacement motor for industrial and residential HVAC air handlers. As a genuine HVAC OEM motor, this 48 frame blower motor delivers a consistent 1/4 HP at 1075 RPM, operating on a 200-230V single-phase circuit. It is engineered to replace legacy and superceded parts including 5KCP39FGV442AS, MOT11051, and MOT3125. Designed for high-duty cycle applications, this permanent split capacitor motor ensures the internal static pressure requirements of Trane and American Standard units are met without compromising airflow velocity.

Technical Benefits for Contractors:

  • Broad Compatibility: Drop-in HVAC motor replacement for several legacy Trane air handler models, eliminating the need for mounting bracket modifications.
  • Electrical Efficiency: Optimized for 230V HVAC motor applications, maintaining stable amperage draw under peak load.
  • Rugged Construction: Built with a NEMA 48 frame diameter and standard shaft dimensions for seamless integration with existing blower wheels.
  • Precision Speed: Single-speed operation at 1075 RPM provides the necessary CFM for consistent heat exchange across evaporator coils.

Common Questions:

Is the Trane MOT18623 a multi-speed motor?
No, this is a single-speed induction motor designed to operate at 1075 RPM. Always verify your wiring diagram to ensure compatibility with single-tap configurations.

Which capacitor is required for this motor?
Most 1/4 HP 1075 RPM 230V motors of this frame size utilize a 5 MFD / 370V capacitor, though you should always verify the rating on the specific MOT18623 nameplate before installation.

Can this replace a motor with a different frame size?
This is a standard 48 frame motor. While it may fit some universal brackets, it is specifically optimized for Trane-specific air handler housings for vibration reduction and proper alignment.
