The **W2TG0-232-R2/UL** is a specialized thermal management component, specifically an **AC axial fan assembly**. These units are typically used in industrial enclosures, server racks, and power supply cabinets to maintain optimal operating temperatures. Below is a detailed breakdown of its electronic and mechanical specifications. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Motor Type** | AC External Rotor Motor | | **Nominal Voltage** | 230V AC | | **Frequency** | 50 / 60 Hz | | **Power Consumption** | ~22W - 30W (Depending on load) | | **Airflow Capacity** | Approx. 160 - 190 m³/h | | **Bearing Type** | Dual Ball Bearing | | **Safety Certification** | UL Recognized (indicated by /UL suffix) | --- ### 2. Electronic Components & Construction #### A. External Rotor Motor Unlike standard motors where the rotor is inside the stator, this fan utilizes an **external rotor design**. The blades are directly attached to the rotor housing. This allows for: * Compact physical dimensions. * Better heat dissipation for the motor itself. * Stable RPM under varying static pressure. #### B. Capacitive Start/Run System As an AC motor, it often utilizes an integrated capacitor to create the necessary phase shift for the magnetic field. This ensures the fan can start reliably under load. #### C. Thermal Protection The "UL" designation implies the inclusion of internal safety mechanisms. Most models in this series include **Impedance Protection** or a **Thermal Switch**. If the fan blades are obstructed (locked rotor), the motor limits the current or cuts power to prevent a fire hazard. --- ### 3. Physical & Material Properties * **Housing:** Typically made of Die-cast aluminum with a black coating to resist corrosion and provide structural rigidity. * **Impeller:** High-performance plastic (PA 6.6) reinforced with glass fiber, designed for aerodynamic efficiency and low noise. * **Wiring:** Usually features two lead wires (L/N) or a terminal block connection, rated for high-temperature environments. --- ### 4. Application Areas * **Electrical Cabinets:** Preventing heat buildup in PLC and motor drive enclosures. * **IT Infrastructure:** Cooling for 19-inch rack-mount equipment. * **HVAC Systems:** Used as an exhaust or circulation fan in small-scale climate control units.
