The **W2AC-AZDA-R2/N** is a specific model of an AC-powered axial fan, typically manufactured by brands like **Wintek** or associated industrial cooling suppliers. This fan is designed for high-performance cooling in server racks, industrial cabinets, and power supplies. --- ### 1. Technical Specifications The following table outlines the primary electronic and physical characteristics: | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 220V - 240V AC | | **Frequency** | 50/60 Hz | | **Current Consumption** | ~0.14A to 0.22A (Model dependent) | | **Power Rating** | Approximately 20W - 38W | | **Bearing Type** | Dual Ball Bearing (Indicated by "B" or "2" in some series) | | **Speed** | 2,500 - 3,000 RPM | | **Airflow** | ~90 - 110 CFM | | **Frame Material** | Die-cast Aluminum (Painted Black) | | **Impeller Material** | Thermoplastic PBT (UL 94V-0 Rated) | --- ### 2. Key Electronic Components #### A. Shaded Pole Induction Motor This fan utilizes a **shaded pole AC motor**. Unlike DC fans that require a complex PCB and hall-effect sensors, shaded pole motors use a copper "shading coil" on a portion of the stator pole to create a lagging magnetic field. This provides the starting torque necessary to spin the blades. #### B. Integrated Protection * **Impedance Protection:** The windings are designed to have high enough impedance that even if the fan is physically locked (rotor stalled), the motor will not overheat or catch fire. * **Insulation Class:** Typically **Class B or F**, allowing the internal copper windings to withstand temperatures up to 130°C–155°C. #### C. Connection Interface The suffix **"R2/N"** usually denotes the wiring configuration: * **Terminals:** Often features two flat male terminals (fast-on type) rather than lead wires, allowing for quick disconnect and replacement. * **Grounding:** The aluminum frame usually includes a grounding screw point to prevent static buildup or electrical leakage. --- ### 3. Usage and Environment * **Operating Temperature:** -10°C to +70°C. * **Life Expectancy:** Approximately 50,000 hours at 40°C due to the dual ball bearing system. * **Safety Certifications:** Usually carries UL, CE, and TUV markings for industrial safety compliance. ---
