The **MA63TAA-R** is a specific model of an **AC Axial Fan**, typically manufactured by companies like **Fulltech Electric**. These fans are engineered for industrial cooling, ventilation, and heat dissipation within electronic enclosures. --- ## Technical Specifications Below are the primary electronic and mechanical characteristics of the MA63TAA-R: | Feature | Specification | | :--- | :--- | | **Input Voltage** | 230V AC (Standard) | | **Frequency** | 50 / 60 Hz | | **Current Consumption** | Approx. 0.23 / 0.20 Amps | | **Power Input** | Approx. 38 / 36 Watts | | **Speed** | 2750 / 3100 RPM | | **Airflow Capacity** | ~200 - 235 CFM | | **Bearing Type** | Dual Ball Bearing | | **Termination** | Terminal (T) - usually "R" denotes Lead Wire or specific RoHS compliance | --- ## Key Electronic Components & Construction ### 1. The Motor (Shaded Pole or Capacitor Run) The core of the MA63TAA-R is an AC induction motor. * **Stator:** Comprised of copper windings and laminated steel cores. * **Rotor:** A permanent magnet or squirrel-cage rotor that reacts to the electromagnetic field generated by the stator. ### 2. Bearing System The "Ball Bearing" system used in this model is superior to sleeve bearings for industrial use. * **Longevity:** Rated for 50,000+ hours of continuous operation. * **Mounting:** Allows the fan to be mounted in any orientation (horizontal, vertical, or angled) without affecting life expectancy. ### 3. Protection Mechanisms * **Impedance Protection:** The motor is designed so that if the fan blade is blocked (locked rotor), the internal resistance prevents the coils from reaching temperatures that would cause a fire. * **Thermal Cut-off:** Many units in this series include an internal thermal fuse to shut down power if the unit exceeds safe operating temperatures. ### 4. Frame and Impeller * **Frame:** Typically made of Die-cast Aluminum, which acts as a heat sink for the motor components. * **Impeller:** Made of reinforced plastic (PBT) or metal, designed for high static pressure to push air through dense electronic components. --- ## Part Number Breakdown (Generic) | Segment | Meaning | | :--- | :--- | | **MA** | Model Series (Fulltech High Performance) | | **63** | Frame Size (indicates dimensions, e.g., 172mm diameter) | | **T** | Terminal connection (instead of lead wires) | | **AA** | Voltage/Speed designation (usually 230V High Speed) | | **-R** | RoHS Compliant or Reinforced version | ---
