The **W2AC-AADA-R** is a specific model of an **AC Axial Fan** manufactured by **Sanyo Denki**, part of their "San Ace" series. These fans are engineered for high reliability and efficient cooling in industrial environments. Below is a breakdown of its electronic and mechanical parts, along with its technical specifications. --- ### 1. Component Breakdown | Part Category | Description | |:---|:---| | **Motor Type** | Capacitor-run induction motor (Single Phase). | | **Housing/Frame** | Die-cast aluminum, providing structural rigidity and heat dissipation. | | **Impeller** | Plastics (UL 94V-0 rated), designed for optimal airflow-to-noise ratio. | | **Bearings** | Dual ball bearings to ensure a long service life (typically 25,000+ hours). | | **Connection** | Lead wires (indicated by the "R" suffix in some naming conventions). | --- ### 2. Technical Specifications The "W2" in the part number typically denotes a frame size of **120mm x 120mm**. | Parameter | Specification | |:---|:---| | **Rated Voltage** | 100V / 115V AC (depending on specific regional tuning) | | **Frequency** | 50 / 60 Hz | | **Frame Size** | 120 x 120 x 38 mm | | **Input Power** | Approx. 14W to 18W | | **Airflow** | ~80 to 100 CFM (Cubic Feet per Minute) | | **Speed** | ~2600 to 3000 RPM | | **Safety Approvals** | UL, CSA, TUV, and CE compliant | --- ### 3. Electronic Safety Features * **Impedance Protection:** The motor is designed so that even if the fan is locked (prevented from spinning), the internal impedance of the coils prevents the temperature from rising to a level that would cause a fire or insulation failure. * **Insulation Class:** Typically Class E or Class B, rated to withstand temperatures up to 120°C. * **Dielectric Strength:** Capable of withstanding 1500V AC for one minute between the lead wires and the frame. --- ### 4. Wiring Diagram Representation For AC fans like the W2AC-AADA-R, the wiring is straightforward as it does not require a DC driver board. ```text [ AC Power Source ] | +----[ Black Wire ]----( Motor Coil ) | | +----[ White Wire ]--------+ | +----[ Green/Yellow ]---( Frame Ground ) ``` ---
