The **W2AC-A32C-R** is a specific model within the series of industrial AC axial fans, typically manufactured by brands like **Wenzhou** or similar industrial cooling suppliers. These units are designed for high-performance cooling in server racks, power supplies, and control cabinets. --- ### 1. Technical Specifications The part number typically breaks down into the following electronic and mechanical characteristics: | Feature | Specification | Description | | :--- | :--- | :--- | | **Input Voltage** | 220V - 240V AC | Standard high-voltage AC input. | | **Frequency** | 50/60 Hz | Dual frequency compatibility. | | **Current / Power** | ~0.14A / 22W | Low power consumption for continuous operation. | | **Dimensions** | 120 x 120 x 32 mm | The "32C" in the name refers to the 32mm thickness. | | **Bearing Type** | Ball Bearing | "R" usually denotes a high-reliability ball bearing system. | | **Speed** | 2500 - 3000 RPM | High-speed rotation for maximum airflow. | --- ### 2. Key Electronic Components The internal construction of the W2AC-A32C-R consists of several critical electronic and electromechanical parts: #### A. Shaded-Pole Motor Most AC fans of this type use a **shaded-pole induction motor**. * **Stator:** Consists of copper windings wrapped around a laminated steel core. * **Rotor:** A squirrel-cage rotor that reacts to the magnetic field to create torque. #### B. Thermal Protection The "R" or specific safety markings often indicate **Impedance Protection**. * If the fan blades are obstructed (locked rotor), the internal resistance of the motor prevents the windings from overheating and catching fire. #### C. Power Connection The unit usually features two connection types depending on the specific sub-model: 1. **Lead Wires:** Two insulated copper wires for direct soldering or crimping. 2. **Terminals:** Two male spade connectors (Faston style) for quick-disconnect cables. --- ### 3. Comparison with Standard Models The "32C" variant is slightly thinner than the standard "38mm" industrial fans, making it an "Electronic Low Profile" solution for tight spaces. | Feature | W2AC-A32C-R (Slim) | Standard AC Fan | | :--- | :--- | :--- | | **Thickness** | 32mm | 38mm | | **Airflow** | ~75-85 CFM | ~95-110 CFM | | **Noise Level** | ~40-45 dB | ~45-50 dB | --- ### 4. Wiring Diagram (Conceptual) Since it is a 220V AC device, there is no polarity (no positive or negative), but grounding the frame is essential for safety if the housing is metallic. ```text [Power Source L] -------- (Term 1) [ Motor ] (Term 2) -------- [Power Source N] | (Housing) --- [ Ground ] ``` ---
