The **W2TG0-3D2-R2** is a specific technical part number, typically associated with high-performance cooling solutions, specifically **AC Axial Fans** manufactured by companies like **EBM-Papst**. Below is a detailed breakdown of the electronic and mechanical specifications for this component. --- ### 1. General Specifications This part is designed for industrial-grade cooling, often used in control cabinets, server racks, or ventilation systems. | Feature | Specification | | :--- | :--- | | **Component Type** | AC Axial Fan | | **Phase** | 1-Phase (Single Phase) | | **Nominal Voltage** | 230 VAC | | **Frequency** | 50 / 60 Hz | | **Speed (RPM)** | Approx. 2700 - 3000 RPM | | **Power Consumption** | ~11 - 13 Watts | | **Bearing Type** | Ball Bearing | --- ### 2. Electronic Components & Construction The W2TG0 series utilizes specific internal electronics to manage AC power and heat dissipation. * **Motor Technology:** It uses a **Shaded-pole motor**. These are self-starting AC single-phase induction motors. They are electronically simple, highly reliable, and require very little maintenance. * **Insulation Class:** Usually **Class B or F**, meaning the internal wiring can withstand temperatures up to 130°C–155°C without the insulation breaking down. * **Protection Circuitry:** * **Impedance Protection:** The motor is designed so that if the fan blade is blocked (rotor lock), the internal resistance (impedance) prevents the current from rising to a level that would cause a fire or melt the windings. * **Connection Type:** Typically features **2 flat terminals** (2.8 x 0.5 mm) for power input, or lead wires depending on the specific suffix. --- ### 3. Materials and Mechanical Parts The "W2TG0" designation also dictates the physical build quality: 1. **Housing:** Die-cast aluminum. This acts as a heat sink for the motor and provides structural rigidity. 2. **Impeller:** Usually made of painted sheet steel or high-grade plastic, directly welded to the external rotor motor. 3. **Airflow Direction:** "V" Exhaust over struts (standard for this series). --- ### 4. Technical Drawing Reference (Example Logic) If you were to interface this with a controller, you would use a standard AC circuit: ```mermaid graph LR A[AC Power L] --> C[Terminal 1] B[AC Power N] --> D[Terminal 2] subgraph Fan_Housing C --> E[Shaded Pole Motor] D --> E end ``` --- ### 5. Environmental Limits * **Operating Temperature:** -25°C to +70°C. * **Service Life (L10):** Typically rated for 30,000 to 40,000 hours at 40°C.
