### M2AC-A30-R2/CE Overview The **M2AC-A30-R2/CE** is a high-performance industrial AC Servo Motor, typically manufactured by **LS Electric (formerly LS Industrial Systems)** as part of their **L7** or **iX7** drive compatibility series. This specific model is designed for high precision, medium inertia, and robust industrial automation tasks. --- ### Technical Specifications The table below highlights the primary electronic and mechanical characteristics: | Parameter | Specification | | :--- | :--- | | **Rated Output** | 3.0 kW (3000 Watts) | | **Rated Speed** | 2,000 RPM | | **Max Speed** | 3,000 RPM | | **Rated Torque** | 14.3 N·m | | **Input Voltage** | AC 200V ~ 230V (3-Phase) | | **Rated Current** | 17.02 A | | **Encoder Type** | Serial Incremental / Absolute (19-bit or higher) | | **Protection Rating** | IP65 (excluding shaft opening) | --- ### Key Electronic Components & Functions #### 1. The Stator & Winding (Permanent Magnet) This motor utilizes a **Permanent Magnet Synchronous Motor (PMSM)** design. The electronic timing of the current flowing through the stator windings creates a rotating magnetic field that interacts with the high-strength neodymium magnets on the rotor to produce torque. #### 2. Feedback System (Encoder) The "R2" designation in the part number often refers to the **Encoder Resolution**. * **Resolution:** Typically features a 19-bit (524,288 pulses per revolution) encoder. * **Function:** It sends real-time data back to the Servo Drive regarding the exact position, speed, and direction of the shaft, allowing for closed-loop control. #### 3. Protection & Insulation * **Thermal Protection:** Built-in thermistors to prevent winding burnout during overloads. * **CE Certification:** The "/CE" suffix confirms the electronics meet European safety, health, and environmental protection requirements, specifically regarding electromagnetic compatibility (EMC). #### 4. Power & Signal Connections The motor features heavy-duty industrial connectors: * **Power Connector:** 4-pin (U, V, W, and Ground). * **Signal/Encoder Connector:** Multi-pin connector for high-speed serial communication with the drive. --- ### Comparison: Standard vs. Brake Models While this specific model (R2/CE) focuses on standard operation, it is often compared to models with internal electromagnetic brakes. | Feature | M2AC-A30-R2/CE (Standard) | M2AC-A30-R2/CEB (Brake) | | :--- | :--- | :--- | | **Holding Brake** | No | Yes (24V DC) | | **Weight** | Lighter | Heavier | | **Application** | Horizontal movement | Vertical (Z-axis) movement | --- ### Typical Wiring Logic ```yaml Motor_Phase_U: Red Motor_Phase_V: White Motor_Phase_W: Black Ground_Wire: Green/Yellow Encoder_Signal: Shielded Twisted Pair ```
