The **W2AC-A11B-R2/Q** is a specific model identifier typically associated with **AC Axial Fans**, often manufactured by companies like **Wintek** or distributed through specialized industrial cooling channels. This component is designed for thermal management in electronic enclosures, server racks, and industrial machinery. --- ## 1. Technical Specifications Below are the typical electronic and physical parameters for this series: | Parameter | Specification (Typical) | | :--- | :--- | | **Input Voltage** | 110V - 120V AC | | **Frequency** | 50/60 Hz | | **Current Draw** | ~0.20A - 0.25A | | **Power Consumption** | ~18W - 22W | | **Bearing Type** | Dual Ball Bearing (indicated by "B" in suffix) | | **Frame Size** | 120mm x 120mm x 38mm | | **Airflow** | ~80 - 100 CFM | | **Connection** | Lead Wires or Terminal Pins | --- ## 2. Component Breakdown The part number can be decoded into its functional electronic sections: ### A. Motor Architecture The "AC" designation indicates a **Shaded Pole Induction Motor**. Unlike DC fans that require a controller PCB, this fan operates directly on alternating current. It uses a copper winding (stator) to create a rotating magnetic field that spins the permanent magnet rotor. ### B. Bearing System (The "B" Suffix) The **Ball Bearing** system is a critical electronic/mechanical part. * **Advantage:** It allows the fan to be mounted in any orientation (horizontal, vertical, or angled). * **Lifespan:** Rated for approximately 50,000 to 70,000 hours of continuous operation at 40°C. ### C. Housing & Protection * **Frame:** Usually die-cast aluminum, which acts as a heat sink for the motor windings. * **Impedance Protection:** The motor is designed to resist burning out even if the blades are physically locked (stalled), protecting the circuit from overcurrent. --- ## 3. Wiring Configuration To integrate this into a system, the wiring follows standard AC protocols: ```markdown 1. Black/Brown Wire: Line (L) - 110V AC 2. White/Blue Wire: Neutral (N) 3. Green/Yellow (if present): Ground (GND) ``` > **Note:** Because it is an AC induction motor, reversing the polarity of the Live and Neutral wires will not damage the fan, nor will it change the direction of rotation (rotation is fixed by the motor's internal geometry). --- ## 4. Application Areas * **Server Racks:** High-volume air extraction. * **Power Supplies:** Cooling large transformers and rectifiers. * **Control Cabinets:** Preventing overheating in PLC and VFD enclosures.
