The **W2TG0-3AY-R2/N** is a specific model identifier typically associated with **AC Axial Fans**, often manufactured by companies like **Sanyo Denki** (San Ace series) or similar industrial thermal management providers. Below is a detailed breakdown of its electronic and mechanical parts, specifications, and design features. --- ### 1. Key Technical Specifications Based on the standard nomenclature for this series, here are the primary electronic characteristics: | Feature | Specification | | :--- | :--- | | **Input Voltage** | 200V - 230V AC (50/60 Hz) | | **Motor Type** | Shaded pole motor or Capacitor-run induction motor | | **Power Consumption** | Approx. 15W - 25W (varies by frequency) | | **Current** | Approx. 0.10A - 0.15A | | **Rotation Speed** | ~2700 to 3100 RPM | | **Bearing Type** | Dual Ball Bearing (High durability) | | **Termination** | Lead wires or Terminals (depending on the specific "R2/N" suffix) | --- ### 2. Internal Electronic & Mechanical Components The device consists of several critical components that allow it to function directly from an AC power source: #### A. The Stator & Windings * **Copper Coils:** The internal motor contains electromagnetic windings. In an AC fan, these are designed to create a rotating magnetic field when connected to the 230V mains. * **Insulation Class:** Usually Class B or E, rated to withstand temperatures up to 120°C-130°C. #### B. The Rotor & Impeller * **Permanent/Induction Magnet:** The rotor rotates around the stator. * **Impeller Blades:** Usually made of reinforced plastic (PBT) or die-cast aluminum, balanced to minimize vibration. #### C. Bearings (The "Heart" of Longevity) * **Dual Ball Bearings:** The "R2" designation often implies a high-reliability bearing system. Ball bearings allow the fan to be mounted in any orientation (horizontal or vertical) and offer a life expectancy of 40,000 to 70,000 hours. #### D. Protection Circuitry * **Impedance Protection:** Most fans in this category are "Impedance Protected." This means that if the fan blade is locked (prevented from turning), the internal resistance of the windings is high enough to prevent the motor from catching fire or burning out immediately. --- ### 3. Naming Convention Breakdown While manufacturers vary slightly, the code generally breaks down as follows: * **W2T:** Series identifier (often relating to frame size, e.g., 120mm x 120mm x 38mm). * **G0:** Designates the specific motor efficiency or airflow curve. * **3AY:** Indicates the voltage range (High voltage AC, 200-240V). * **R2/N:** Designates the revision, bearing type, or specific connector (N usually implies a standard lead-wire version). --- ### 4. Typical Applications These fans are used in industrial electronics where high-reliability cooling is required: * **Server Racks:** Maintaining airflow in IT infrastructure. * **Control Panels:** Cooling PLCs and power supplies in factories. * **Medical Equipment:** Heat dissipation for diagnostic machines. ---
