The **W2AC-AB3Y-R2/N** is a specific model identifier typically associated with **AC Axial Fans** or industrial cooling components, often manufactured by brands like **Fulltech** or specialized industrial suppliers. These units are designed for high-performance thermal management in server racks, control cabinets, and industrial machinery. Below is a breakdown of the electronic and mechanical components of this part. --- ### 1. Technical Specifications The model name reveals the electrical characteristics and physical dimensions of the component. | Parameter | Specification (Typical) | | :--- | :--- | | **Input Voltage** | 220V - 240V AC | | **Frequency** | 50/60 Hz | | **Bearing Type** | Dual Ball Bearing (indicated by 'B') | | **Dimensions** | 120mm x 120mm x 38mm (Standard Square) | | **Housing Material** | Die-cast Aluminum | | **Impeller Material** | Thermoplastic (UL 94V-0) or Steel | | **Termination** | Lead Wires (indicated by '/N' or 'R2' variants) | --- ### 2. Key Electronic Components The "Electronic Parts" of an AC fan like the W2AC-AB3Y-R2/N are primarily located within the motor hub: #### A. Shaded Pole or Capacitor-Run Motor * **Stator Windings:** Copper coils that create a rotating magnetic field when AC power is applied. * **Rotor:** A permanent magnet or induction rotor that reacts to the stator's field to create rotation. #### B. Thermal Protection * **Impedance Protection:** The motor is designed so that if the fan blade is stalled, the internal resistance (impedance) prevents the coils from drawing enough current to catch fire. * **Thermal Cut-off:** Many models include a thermal fuse that breaks the circuit if internal temperatures exceed safe operating limits (usually >100°C). #### C. Bearings and Grounding * **Dual Ball Bearings:** Provide high MTBF (Mean Time Between Failure), typically rated for 50,000+ hours of continuous use. * **Grounding Point:** The aluminum frame usually features a dedicated grounding screw point to prevent static buildup or electrical leakage. --- ### 3. Part Number Decoder (Breakdown) While naming conventions vary slightly by manufacturer, here is how this specific string is generally interpreted: 1. **W2AC:** Series designation (AC Axial Fan). 2. **AB3Y:** Speed and Airflow rating (High-speed variant). 3. **R2:** Revision 2 or specific mounting hole configuration. 4. **N:** Connection type (usually signifying "Natural" or standard lead wire exit). --- ### 4. Application Areas * **Power Supplies:** Heat dissipation for high-wattage industrial PSUs. * **IT Infrastructure:** Cooling for 19-inch server racks. * **Medical Equipment:** Reliable ventilation for laboratory diagnostic machines.
