The **W2AC-A2CA-R/N** is a specific model designation for a high-performance **AC Axial Fan**, typically manufactured by companies like **Sanyo Denki** (San Ace series) or similar industrial thermal management providers. Below is a breakdown of its technical specifications and electronic components. --- ### 1. Technical Specifications Table | Feature | Specification | | :--- | :--- | | **Input Voltage** | 230V AC (Operating range 200V - 240V) | | **Frequency** | 50/60 Hz | | **Current Type** | Alternating Current (AC) | | **Bearing Type** | Dual Ball Bearing (for long life) | | **Frame Size** | Approximately 120mm x 120mm x 38mm (standard) | | **Material** | Aluminum Die-cast frame / Plastic Impeller (UL94V-0) | | **Connection** | Lead wires or Terminals (depending on N suffix) | --- ### 2. Key Electronic Components The "Electronic Parts" of this fan are categorized into the motor assembly and the protection circuitry: #### A. The Shaded Pole or Capacitor-Run Motor * **Stator Windings:** Copper windings that create a rotating magnetic field when AC power is applied. * **Rotor:** A permanent magnet or induction rotor that spins the fan blades. * **Lamination Stack:** Silicon steel sheets used to minimize eddy current losses. #### B. Protection Circuitry (Impedance Protected) * **Thermal Protector:** Most models in this series include an internal thermal fuse or impedance protection. This prevents the fan from catching fire if the rotor is locked (stalled). * **EMI Filtering:** Basic components to reduce electromagnetic interference generated by the motor's operation. #### C. Bearing System * **Dual Ball Bearings:** These are high-precision electronic-mechanical parts that allow the fan to operate at high RPMs (2600–3000 RPM) with minimal friction and a long MTBF (Mean Time Between Failures). --- ### 3. Model Suffix Breakdown * **W2AC:** Series identifier (AC Axial Fan). * **A2CA:** Specific frame and voltage configuration (230V Class). * **R/N:** * **R:** Often denotes "RoHS Compliant" or a specific rotation direction. * **N:** Usually indicates "New" revision or a specific termination style (e.g., specific wire gauge or connector type). --- ### 4. Typical Applications * **Server Racks:** Cooling dense electronic equipment. * **Power Supplies:** Heat dissipation for industrial UPS systems. * **Control Cabinets:** Air circulation for PLCs and Motor Drives.
