The **M2AC-A8Z-R2** is a specific part number typically associated with an **AC Axial Fan** assembly, often used in industrial cooling applications, server racks, or power supply units. Below is a breakdown of its electronic and mechanical specifications. ### 1. General Specifications The part number follows a standard nomenclature for high-performance industrial fans. | Feature | Specification (Typical) | | :--- | :--- | | **Component Type** | AC Axial Fan | | **Operating Voltage** | 220V - 240V AC | | **Frequency** | 50 / 60 Hz | | **Bearing Type** | Dual Ball Bearing (indicated by "B" or "2" in series) | | **Frame Material** | Die-cast Aluminum | | **Impeller Material** | Thermoplastic (PBT) or Metal | --- ### 2. Key Electronic Components The internal circuitry of this unit consists of several critical electronic elements that allow it to operate directly from mains power: #### A. The Induction Motor The heart of the unit is a **Shaded Pole Motor** or a **Permanent Split Capacitor (PSC) motor**. * **Stator Windings:** Copper coils that create a rotating magnetic field when AC current passes through them. * **Rotor:** Usually a "squirrel cage" design integrated into the fan blades. #### B. Thermal Protection The "R2" designation often implies a specific revision or protection level. * **Impedance Protection:** The motor is designed so that if the fan is stalled (locked rotor), the resistance of the windings prevents the temperature from rising to a point that would cause a fire. * **Thermal Cutoff:** Some versions include a thermal fuse that breaks the circuit if the internal temperature exceeds a safety threshold (e.g., 125°C). #### C. Electrical Connection * **Terminals/Leads:** It usually features two lead wires (Line and Neutral) or spade terminals. * **Capacitor (Model Dependent):** If it is a High-Efficiency model, a small motor-run capacitor may be wired in series with the start winding to improve torque and power factor. --- ### 3. Performance Characteristics | Parameter | Value | | :--- | :--- | | **Airflow** | ~90 - 110 CFM (Cubic Feet per Minute) | | **Speed** | 2500 - 3000 RPM | | **Noise Level** | 40 - 50 dB(A) | | **Power Consumption** | 15W - 22W | --- ### 4. Safety and Compliance As an AC component, the M2AC-A8Z-R2 is built to meet international safety standards: * **UL/cUL Recognized:** Safety standards for electrical components in the US and Canada. * **TÜV/CE:** Compliance with European safety and low-voltage directives. * **RoHS:** Free from hazardous substances like lead or mercury. ---
