The **W2TG0-2CY-R2** is a specific part number typically associated with high-performance cooling solutions, most commonly found in **Delta Electronics** or industrial fan assemblies used in server hardware (like Dell or HP networking equipment). Below is a breakdown of the electronic components and technical specifications associated with this part. --- ### 1. General Specifications This part is a high-speed axial fan designed for precision cooling in dense electronic environments. | Feature | Specification | | :--- | :--- | | **Manufacturer** | Delta Electronics (commonly) | | **Type** | Axial DC Fan | | **Voltage** | 12V DC (Standard) | | **Connector** | 4-Pin / 6-Pin (PWM & Tachometer support) | | **Bearing Type** | Dual Ball Bearing | | **Application** | Servers, Routers, Power Supplies | --- ### 2. Core Electronic Components The internal PCB (Printed Circuit Board) of the W2TG0-2CY-R2 consists of several critical electronic elements: #### A. The Brushless DC (BLDC) Motor * **Stator & Rotor:** Uses a permanent magnet rotor and a wire-wound stator. * **Phase Switching:** Since it is brushless, it uses electronic commutation instead of physical brushes, increasing lifespan and reducing EMI (Electromagnetic Interference). #### B. Integrated Circuit (IC) Controller * **PWM Control:** The internal IC interprets the **Pulse Width Modulation** signal from the motherboard to adjust the fan speed dynamically. * **Soft Start:** Electronics designed to prevent current spikes during initial power-up. #### C. Sensors * **Hall Effect Sensor:** A small magnetic sensor that detects the position of the rotor to manage commutation and provide the **Tachometer (FG)** signal. * **Thermal Protection:** Often includes an internal thermistor to shut down the fan if the internal motor coils exceed safe operating temperatures. --- ### 3. Pinout Configuration For the R2 revision, the wiring typically follows the industrial standard for intelligent cooling: | Pin Color | Function | Description | | :--- | :--- | :--- | | **Black** | GND | Ground / Negative Power | | **Red** | VCC | +12V DC Power Supply | | **Yellow** | Tach (FG) | Frequency Generator (Speed output to system) | | **Blue** | PWM | Control signal input from the system | --- ### 4. Technical Characteristics * **High Static Pressure:** The blade geometry is optimized for pushing air through dense heat sinks or filtered chassis. * **Locked Rotor Protection:** The electronics will automatically cut power if the blades are physically obstructed to prevent the motor from burning out. * **Polarity Protection:** Prevents damage if the positive and negative wires are accidentally reversed. ---
