The **W2CE-53A-R** is a specific part number belonging to a series of **AC Axial Fans**, typically manufactured by brands like **Nidec (formerly Lear/Interfan)**. These fans are widely used for cooling electrical enclosures, server racks, and industrial machinery. Below is the breakdown of its electronic and mechanical specifications. ### 1. Technical Specifications The "W2CE" series generally refers to high-performance, dual-voltage, or specific frame-size AC fans. | Feature | Specification | | :--- | :--- | | **Motor Type** | Shaded Pole Induction Motor (Single Phase) | | **Operating Voltage** | 220V - 240V AC | | **Frequency** | 50 / 60 Hz | | **Input Power** | ~20W - 30W (Depending on specific load) | | **Speed** | ~2700 - 3000 RPM | | **Bearing Type** | Dual Ball Bearing (indicated by "B" or "C" in many AC series) | | **Termination** | Terminals (standard fast-on type) or Lead Wires | --- ### 2. Internal Electronic Components Unlike DC fans that use a PCB with a brushless controller, the W2CE-53A-R relies on electromagnetic induction: * **Stator Windings:** Copper coils wrapped around a laminated steel core. These create the magnetic field necessary to rotate the rotor. * **Impedance Protection:** The "R" or specific suffix usually indicates that the motor is **Impedance Protected**. This means that if the fan blade is blocked (locked rotor), the internal resistance of the windings prevents the motor from drawing enough current to catch fire. * **Insulation Class:** Typically **Class B or F**, rated for temperatures up to 130°C–155°C. * **Capacitor (Optional):** Some high-torque AC fans include a starting capacitor, though most shaded-pole AC fans in this frame size are self-starting via a shading ring on the stator pole. --- ### 3. Mechanical & Environmental Characteristics * **Frame Material:** Die-cast aluminum (provides heat dissipation and EMI shielding). * **Blade Material:** Thermoplastic (PBT) or Magnesium alloy (UL94V-0 rated). * **Mounting:** Standard 120mm x 120mm x 38mm form factor (Industry standard "12038" size). * **Airflow Direction:** Typically "S" (Strut side) or "L" (Lead side), exhausting air over the motor struts. --- ### 4. Wiring Diagram (Typical) Since this is an AC-powered device, the wiring is straightforward: ```text [ Power Source: 230VAC ] | +-----+-----+ | | [Terminal 1] [Terminal 2] | | +---( FAN )---+ ``` *Note: As an AC fan, it is not polarity sensitive, but a Ground (PE) connection to the metal frame is required for safety.* ---
