The **W2TG0-1AC-R2** is a specific model number primarily associated with **AC Axial Fans**, typically manufactured by brands like **EBM-Papst** (or similar industrial cooling providers). It is designed for thermal management in industrial equipment, server racks, and power supplies. --- ## 1. Technical Specifications The following table outlines the key electronic and physical characteristics of the W2TG0-1AC-R2: | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 115V AC (Standard AC Line Voltage) | | **Frequency** | 50 / 60 Hz | | **Current Consumption** | Approx. 0.18 A - 0.25 A (depending on load) | | **Power Consumption** | ~18W to 22W | | **Bearing Type** | Dual Ball Bearing (for long life and high temp) | | **Connection Type** | Lead Wires (usually 2-wire) or Terminal Lugs | | **Material** | Die-cast aluminum housing; Plastic or Metal impeller | --- ## 2. Key Electronic Components & Design The internal electronics of this unit are designed for durability and constant-speed operation: ### A. Shaded Pole Motor The device utilizes a **Shaded Pole AC Induction Motor**. - **Simplicity:** It does not require a starting capacitor, making it more robust against electronic failure. - **Self-Starting:** The copper "shading rings" on the stator poles create a rotating magnetic field to start the rotor. ### B. Impedance Protection The "AC" series fans often feature **Impedance Protection**: - If the fan blade is obstructed (locked rotor), the internal resistance of the motor windings prevents the current from rising to a level that would cause a fire or melt the insulation. ### C. Ball Bearing System Unlike sleeve bearings, the **dual ball bearing** system used in the R2 variant is designed to: - Handle higher ambient temperatures (up to 70°C). - Allow the fan to be mounted in any orientation (horizontal, vertical, or angled) without affecting the lifespan of the motor. --- ## 3. Wiring Diagram Concept Since this is an AC-driven part, the wiring is straightforward. Below is a conceptual representation: ```text [ AC Power Source ] | | (Line/Hot) (Neutral) | | [--- Black --- White ---] [ Motor ] [-----------------------] ``` *Note: Some industrial variants include a Green/Yellow wire for Earth Grounding to the metal chassis.* --- ## 4. Common Applications * **Enclosure Cooling:** Dissipating heat from electrical control panels. * **IT Infrastructure:** Cooling for 19-inch rack-mount servers. * **Industrial Machinery:** Providing airflow for high-wattage power supplies or CNC controllers.
