The **M2AC-A4E-R2/Q** is a specific model identifier typically associated with **Delta Electronics' ASDA-A2 Series** AC Servo Motors. This specific configuration defines the electrical characteristics, feedback systems, and mechanical build of the motor. --- ### 1. Technical Specifications Breakdown The alphanumeric code represents specific electronic and mechanical parameters: | Code Segment | Description | Details | | :--- | :--- | :--- | | **M2** | **Motor Series** | Part of the ECMA high-performance motor series. | | **AC** | **Input Voltage** | 220V AC (Standard Single/Three Phase). | | **A4** | **Rated Power** | 400 Watts (0.4 kW). | | **E** | **Frame Size** | 60mm frame size. | | **R** | **Encoder Type** | 20-bit Incremental Encoder (1,280,000 pulses/rev). | | **2** | **Shaft/Brake** | Round shaft with oil seal (standard). | | **Q** | **Special Code** | Often indicates specific connector types or custom factory settings. | --- ### 2. Key Electronic Components #### A. The High-Resolution Encoder The most critical electronic part is the **20-bit encoder**. * **Function:** It provides real-time position and speed feedback to the Servo Drive. * **Precision:** With 1,280,000 pulses per revolution, it allows for extremely smooth motion and high-precision positioning (down to the micron level). #### B. Permanent Magnet Synchronous Motor (PMSM) Stator The internal "electronic" heart consists of three-phase copper windings. * **Winding Insulation:** Class F insulation for heat resistance. * **Magnets:** High-coercivity rare-earth magnets on the rotor to ensure high torque density and low inertia. #### C. Connectivity & Wiring The motor utilizes specialized connectors to manage the high-frequency switching noise (EMI): * **Power Connector:** U, V, W, and Ground pins for the 3-phase AC input. * **Encoder Connector:** High-speed differential signaling to ensure data integrity over long cable runs. --- ### 3. Compatible Drive System To operate these electronic parts, the motor must be paired with an AC Servo Drive (e.g., **ASD-A2-0421-L**). The drive manages: 1. **Pulse Width Modulation (PWM):** Converting DC bus voltage into AC to drive the motor. 2. **PID Loop Control:** Adjusting current based on the encoder's feedback. --- ### 4. Application Parameters | Parameter | Value | | :--- | :--- | | **Rated Speed** | 3000 RPM | | **Max Speed** | 5000 RPM | | **Rated Torque** | 1.27 N-m | | **Peak Torque** | 3.82 N-m | ---
