Weg Motors 14409117 W22 Cooling Tower NEMA Premium Efficiency 50 HP 6P 364/5T 3Ph 208-230/460//380 V 60//50 Hz IC410 - TEAO - Foot-mounted-05012AT3ECT365TF1-W2

A 50 HP, 6-pole, TEAO cooling tower motor for compatible commercial and industrial HVAC equipment.

Cooling towers are important components in commercial and industrial HVAC systems. They help reject heat from circulating water and support the operation of chillers and other cooling equipment. When a cooling tower motor fails or operates outside its intended conditions, it can affect system performance, increase maintenance demands, and lead to unplanned downtime.

The WEG 14409117 / 05012AT3ECT365TF1-W2 is a 50 HP, 6-pole W22 Cooling Tower motor designed for compatible cooling tower applications. Its listed configuration includes three-phase operation, a TEAO enclosure, and foot-mounted construction.

WEG's cooling tower motor family is designed for challenging environments, including applications involving high humidity and corrosive exposure. Selecting the correct enclosure, mounting arrangement, electrical ratings, and motor speed is essential to achieving compatibility with the cooling tower equipment.

Technical Specifications

Built for Cooling Tower Systems That Depend on Reliable Operation

Cooling tower fans and drive systems need dependable motor operation to support heat rejection and maintain the intended performance of connected HVAC equipment. An incorrectly selected or failing motor can contribute to reduced cooling performance, equipment interruptions, and additional maintenance work.

The WEG 14409117 is identified as a cooling tower motor. Its 50 HP rating and 6-pole design provide the power and speed configuration for compatible cooling tower installations. Selecting a motor that matches the original equipment's electrical and mechanical requirements helps support dependable operation and makes replacement planning more straightforward.

Key Features of the WEG 14409117

50 HP, Three-Phase Power

The motor is rated at 50 HP for three-phase operation at 208-230/460 V, 60 Hz, and 380 V, 50 Hz. These ratings should be checked against the facility's power supply and the cooling tower manufacturer's requirements before installation.

6-Pole Design

A 6-pole motor operating on a 60 Hz supply has a synchronous speed of approximately 1200 RPM. Its actual rated speed under load is lower and should be confirmed using the motor's nameplate or detailed manufacturer documentation.

TEAO Enclosure (IC410)

The totally enclosed air-over design is intended for installations where cooling air is provided over the motor by the surrounding equipment or application airflow.

Foot-Mounted Construction

The motor is foot-mounted. Frame size, foot dimensions, shaft configuration and mounting orientation must match the existing installation.

NEMA Premium Efficiency

The NEMA Premium classification is a useful specification when evaluating operating costs in systems that run for extended periods.

Why the 6-Pole Motor Design Matters

Motor speed is an important factor in cooling tower equipment selection. The motor's speed affects how it works with the connected fan, gearbox, or other driven components. Using the correct speed helps maintain the equipment's intended operating characteristics.

Motor Speed → Direct Drive or Gearbox → Fan Speed → Heat Rejection

Before replacing a motor, verify whether the cooling tower uses direct drive or a geared arrangement and confirm the required motor speed with the original equipment manufacturer.

TEAO vs. TEFC: Cooling Method Differences

Cooling tower motors may encounter high humidity and potentially corrosive environmental conditions. The WEG 14409117 uses a TEAO enclosure, which differs from a TEFC motor that uses its own external cooling fan.

Because the airflow and installation requirements differ, TEAO and TEFC motors should not be treated as interchangeable without confirming suitability for the particular cooling tower. TEAO also does not mean that a motor is waterproof or suitable for immersion; the installation environment, airflow, mounting orientation, and protection from contaminants must comply with the manufacturer's instructions.

Frame and Mounting Compatibility

Mounting compatibility is critical when replacing a cooling tower motor. Differences in frame size, foot dimensions, shaft configuration, or mounting orientation can prevent a replacement from fitting correctly or operating as intended.

The catalog number includes 365T, while the product title identifies 364/5T. Confirm the exact frame and mounting dimensions against WEG's documentation and the existing motor before ordering.

Real Impact on Cooling Tower Equipment

Commercial Building Cooling Towers

A commercial building depends on its cooling tower to reject heat from the HVAC system. Where the original equipment requires a compatible 50 HP, 6-pole cooling tower motor, the WEG 14409117 can be evaluated as a replacement option. Confirming voltage, frame, mounting, shaft, and enclosure before ordering helps reduce the risk of a mismatch.

Industrial Cooling Infrastructure

Industrial facilities may use cooling towers as part of their process cooling systems. Unexpected motor downtime can interrupt normal operations. Selecting a correctly specified motor helps maintenance teams plan replacement work while keeping the motor aligned with the cooling tower's original design requirements.

HVAC Heat-Rejection Equipment

The motor can be considered for compatible cooling tower fan drives and large cooling tower motor replacements in facilities with a matching three-phase electrical supply.

Check Before You Order

• Horsepower and rated speed
• Voltage, phase, and frequency
• NEMA frame
• Mounting arrangement
• Shaft dimensions and configuration
• Enclosure and cooling method
• Cooling tower application requirements
• Physical dimensions and clearances
• Nameplate and manufacturer requirements

Selecting a replacement motor based only on horsepower can lead to compatibility issues. Confirming these details helps reduce the risk of ordering a motor that does not fit or meet the equipment's operating requirements.

NEMA Premium Efficiency and Operating Considerations

Efficiency is one factor to consider when evaluating motor operating costs, particularly in systems that run for extended periods. Actual energy consumption depends on the connected load, operating hours, system design, and operating conditions. Correct motor sizing, installation, and maintenance are also important to achieving the intended performance.
