The **W2TG0-3C2-R** is a specific model of an AC axial fan manufactured by **Sanyo Denki**, part of their "San Ace" series. These fans are known for high reliability and are typically used in industrial cooling applications. --- ## 1. Technical Specifications The following table summarizes the core electronic and mechanical parameters for this specific part: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Sanyo Denki | | **Input Voltage** | 230V AC (Single Phase) | | **Frequency** | 50 / 60 Hz | | **Current** | Approx. 0.08A - 0.12A (varies by load) | | **Input Power** | ~18W to 20W | | **Speed** | 2,700 to 3,100 RPM | | **Airflow** | ~50 to 60 CFM | | **Bearing Type** | Dual Ball Bearing | | **Termination** | Lead Wires (usually R = RoHS compliant) | --- ## 2. Key Electronic Components & Features ### A. Induction Motor Structure As an AC fan, it utilizes a **shaded-pole induction motor** or a **permanent split capacitor motor**. - **Stator:** Consists of copper windings that create a rotating magnetic field when connected to the 230V source. - **Rotor:** A squirrel-cage design that reacts to the magnetic field to create torque. ### B. Bearing System The "Ball Bearing" system is a critical electronic-mechanical interface. - It reduces friction significantly compared to sleeve bearings. - It allows the fan to operate at higher temperatures and provides a longer **L10 life expectancy** (typically 40,000 to 70,000 hours). ### C. Impedance Protection The "3C2" designation often implies internal **Impedance Protection**. - If the fan blades are locked (locked rotor), the impedance of the coils is high enough to prevent the current from rising to a level that would burn out the motor windings. - This acts as a passive safety mechanism without needing a thermal cutout. ### D. Material and Build - **Frame:** Usually Die-cast aluminum, which acts as a heat sink for the motor windings. - **Impeller:** Plastic (UL 94V-0 rated) to balance weight and safety. --- ## 3. Wiring Configuration The part typically features two lead wires for power input. Since it is an AC device, polarity is generally not an issue for basic operation, though grounding to the metal frame is recommended for safety in industrial environments. ---
