The **W2AC-A1BB-R/Q** is a part number typically associated with high-performance **thermal management solutions**, specifically AC axial fans manufactured by **Sanyo Denki** (San Ace series). These components are designed for high-reliability cooling in industrial, server, and telecommunications equipment. --- ### 🛠️ Technical Specifications & Features Below is a breakdown of the typical electronic and mechanical characteristics for this series: | Parameter | Specification (Typical) | | :--- | :--- | | **Component Type** | AC Axial Fan | | **Input Voltage** | 100V - 120V AC (50/60Hz) | | **Bearing Type** | Dual Ball Bearing (Long Life) | | **Frame Material** | Aluminum Die-cast | | **Impeller Material** | Plastic (UL 94V-0 Rated) | | **Protection** | Burnout protection at locked rotor | | **Termination** | Lead wires or Terminal (R/Q variation) | --- ### 🔍 Key Electronic Components The fan assembly contains several critical electronic parts to manage the AC power and rotation: 1. **Shaded-Pole or Capacitor-Run Motor**: * Uses electromagnetic induction to rotate the blades without the need for brushes. This reduces electronic noise and increases lifespan. 2. **Stator Windings**: * High-quality copper coils insulated to withstand heat. These create the rotating magnetic field when AC current passes through. 3. **Ball Bearing System**: * The "A1BB" designation often refers to a specific bearing and frame configuration. Dual ball bearings allow the fan to operate at high temperatures (up to 70°C) for over 40,000 to 70,000 hours. 4. **Impedance Protection**: * Built-in electronic resistance that prevents the motor from catching fire if the fan blades are physically obstructed (locked rotor). --- ### 📋 Applications * **Control Panels**: Exhausting heat from industrial automation cabinets. * **Power Supplies**: Cooling high-wattage AC-DC converters. * **Medical Equipment**: Reliable cooling for diagnostic machines. * **Networking**: Cooling for rack-mounted switches and routers. --- ### ⚠️ Part Number Suffix Logic * **"R/Q"**: Usually denotes specific packaging, certification standards (like UL/CSA/TUV), or specific terminal connectors rather than bare lead wires. * **"W2AC"**: Identifies the specific frame size and voltage class within the San Ace family.
