The **W2PE-54WD-R/UL** is a specialized electronic component commonly used in power distribution and cooling systems. It is primarily identified as an **AC axial fan assembly** or a high-performance fan unit typically integrated into server racks, industrial cabinets, or high-end power supplies. --- ### 1. General Specifications Based on the part number nomenclature (often associated with manufacturers like **Nidec** or **Sanyo Denki** in specific configurations), here are the typical technical characteristics: | Feature | Specification (Typical) | | :--- | :--- | | **Component Type** | AC Axial Fan / Cooling Unit | | **Voltage Rating** | 100V - 120V AC (50/60Hz) | | **Connector Type** | Lead wires or terminal-based (R-type suffix) | | **Certification** | UL (Underwriters Laboratories) Recognized | | **Bearing Type** | Dual Ball Bearing (for long life) | | **Safety Standard** | Impedance protected or Thermally protected | --- ### 2. Breakdown of the Part Number The alphanumeric string provides specific details about the part's construction: * **W2PE**: Series identifier, often denoting the frame size and motor design (likely 120mm x 120mm x 38mm). * **54**: Refers to the specific performance curve (airflow vs. static pressure). * **WD**: High-speed or Wide-voltage range designation. * **R**: Generally indicates the rotation direction or a specific lead-wire/plug configuration. * **UL**: Indicates the part meets US safety standards for electrical components. --- ### 3. Key Electronic Components Inside As an AC-powered cooling component, the "Electronic Parts" within the unit include: 1. **Stator Windings:** Copper coils that create the magnetic field to drive the rotor. 2. **Permanent Magnet Rotor:** The rotating part attached to the blades. 3. **Capacitor (Internal):** Used for phase-shifting in single-phase AC motors to ensure the fan starts in the correct direction. 4. **Thermal Protector:** A fuse or bimetallic switch that cuts power if the motor exceeds a specific temperature to prevent fire. ### 4. Application Areas * **Data Centers:** Used in PDUs (Power Distribution Units) or rack-mounted equipment. * **Industrial Controls:** Cooling for CNC machines or PLC cabinets. * **Medical Equipment:** Heat dissipation for high-power imaging or laboratory tools. ---
