The **W2AC-AZCA-R** is a specific model of an **AC Axial Fan** manufactured by **ebm-papst**. It is widely used for cooling electronics, ventilation in server racks, and thermal management in industrial equipment. --- ## 1. Technical Specifications Below are the primary electronic and mechanical specifications for this component: | Feature | Specification | | :--- | :--- | | **Manufacturer** | ebm-papst | | **Input Voltage** | 115 VAC | | **Frequency** | 50 / 60 Hz | | **Airflow** | ~106.0 CFM (180.0 m³/h) | | **Power Consumption** | 22 W (at 50Hz) / 21 W (at 60Hz) | | **Bearing Type** | Ball Bearing | | **Dimensions** | 172mm x 150mm x 38mm | | **Weight** | 0.82 kg | | **Termination** | 2 Flat Plugs (Faston connectors) | --- ## 2. Key Electronic Components & Design The internal architecture of the W2AC-AZCA-R consists of several critical electronic sub-assemblies: ### A. Shaded-Pole Motor This fan utilizes a shaded-pole AC motor. This is a type of single-phase induction motor that is valued for its simplicity, reliability, and lack of brushes, which reduces electronic noise and mechanical wear. ### B. Impedance Protection One of the most important electronic safety features is **impedance protection**. - If the fan rotor is stalled (locked), the internal impedance of the motor windings limits the current flow. - This prevents the motor from overheating or catching fire without needing external fuses. ### C. Bearing System The unit uses high-precision **ball bearings**. Electronically, this reduces the torque required for startup and ensures consistent performance across a wide temperature range (-25°C to +70°C). ### D. Housing and Grounding The housing is typically made of **die-cast aluminum**. It includes a grounding lug to ensure that any static buildup or electrical faults are safely shunted to the chassis ground, protecting sensitive nearby electronic components. --- ## 3. Wiring Configuration The fan is designed for simple integration into AC circuits. ```yaml Connection: 2-Pin (L/N) Voltage: 115V AC Connector Type: 2.8 x 0.5 mm (Flat plugs) Protection Class: I (Protective Earth) ``` ---
