The **W2TG0-332-R/N** is a specific model within the family of **Miniature AC External Rotor Motor Axial Fans**. These components are widely used in industrial cooling, ventilation, and electronic equipment thermal management. --- ### Technical Specifications Below is a breakdown of the typical electronic and physical parameters for this component: | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 220V - 230V AC | | **Frequency** | 50/60 Hz | | **Power Consumption** | ~18W to 22W | | **Current** | ~0.10A to 0.12A | | **Speed (RPM)** | 2,400 to 2,800 RPM | | **Airflow Capacity** | ~70 to 90 CFM | | **Bearing Type** | Dual Ball Bearing | | **Frame Material** | Die-cast Aluminum Alloy | --- ### Core Electronic Components #### 1. External Rotor Motor Unlike standard motors where the internal shaft spins, the **external rotor** design has the motor's housing (stator) on the inside, while the rotor (with the blades attached) rotates around it. * **Benefit:** Provides a more compact design and better heat dissipation for the motor coils because they are exposed to the airflow. #### 2. Induction Coil & Stator The stator consists of copper windings that create a magnetic field when AC power is applied. * **Protection:** Most "R/N" series fans include **Impedance Protection**. This means that if the fan blade is obstructed (locked rotor), the internal resistance of the windings prevents the motor from overheating or catching fire. #### 3. Capacitor (Integrated) As an AC motor, it typically utilizes a permanent split capacitor (PSC) design to create the necessary phase shift for the magnetic field to initiate rotation. In the W2TG0 series, this is often integrated within the housing. #### 4. Connection Interface * **Suffix "R/N":** Usually indicates the terminal or lead-wire configuration. * **Lead Wires:** Typically comes with two UL-certified wires (Live and Neutral) for direct connection to an AC power source. --- ### Environmental & Durability Features * **Insulation Class:** Usually rated **Class B** or **Class F**, allowing the internal electronics to operate safely at temperatures up to 120°C–155°C. * **Ball Bearings:** The use of dual ball bearings ensures the electronic motor can operate in any orientation (horizontal or vertical) with a lifespan often exceeding 50,000 hours. * **EMC Compliance:** Designed to minimize electromagnetic interference, making it safe to use near sensitive electronic controllers or medical equipment. ---
