The Trane MOT14556 Motor is a high-performance direct drive blower motor designed for critical applications in residential and light commercial HVAC units. Engineered with a 1/8 HP (100W) output, this 145mm frame motor operates on a 208-230V single-phase power supply at both 50Hz and 60Hz. As a 6-pole induction motor, it maintains a steady 705 RPM across three-speed taps, allowing contractors to fine-tune airflow based on specific system static pressure requirements. The TENV (Totally Enclosed Non-Ventilated) enclosure is a key technical advantage, as it prevents the pull-through of dust, moisture, and contaminants into the internal windings, ensuring long-term reliability in demanding environments where open-vented motors often fail prematurely.

Key Benefits:

• Flexible Speed Control: The 3-speed configuration allows for precise CFM adjustments to match multi-stage heating or cooling demands.
• Superior Protection: Totally Enclosed Non-Ventilated (TENV) design protects the stator and rotor from environmental debris.
• Universal Electrical Compatibility: Rated for 208-230V and dual-frequency 50/60 Hz operation, making it a versatile drop-in replacement.
• High Efficiency: Optimized 100W power consumption provides consistent torque while reducing operational draw.
• Compact Footprint: A 244mm motor height and standard 145mm frame ensure fitment in tight air handler cabinets and blower housings.

Common Questions:

What are the wiring requirements for the three-speed taps?
The Trane MOT14556 uses standard color-coded leads for High, Medium, and Low speed connections. Always refer to the specific unit’s wiring diagram to ensure proper capacitor matching and common line placement.

Can this motor replace an open-drip proof (ODP) motor?
Yes, provided the frame size (145mm) and electrical specifications match. Moving to a TENV enclosure provides superior protection against the dust buildup commonly found in return air plenums.

Is the capacitor included with the MOT14556?
This is the motor only. To ensure the 705 RPM performance and prevent overheating, always install a new run capacitor according to the microfarad (MFD) rating specified on the motor nameplate.
