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 It is engineered to replace legacy and superceded parts including 5KCP39FGV442AS, MOT11051, and MOT3125.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.

QUESTIONS & ANSWERS

Ask a Question

  • Is this Trane MOT11051 a direct replacement for the GE 5kcp39fg v442as, all specs seam the same accept I'm unsure of rotation on the original, rpm is 1100 vs 1075 not worried about that, volts same etc. Does this come w/ new cap. Or do I need order that separate, 5mfd 370v

    Online sources from other vendor does show that MOT11051 is the replacement for 5kcp39fgv442as however we are not able to confirm that with factory. The best way is reply with your unit model number so we can confirm with factory to be sure which motor is the correct one. This motor comes without capacitor and you can see the capacitor from the link below.

  • Is the rotation reversible on the Trane MOT11051

    No, it is not reversible. If you can't find the right motor for your unit please reply with the model number of your unit we will find that out for you from the factory.

  • Is the shaft short like mot11051 and do you stall this from screw up top of motor or install screws on side.

    It does not appear to be as short has the original, but it is the factory’s suggested replacement.
