The **M2AC-A83-R/CE** is a high-performance, industrial-grade AC Servo Motor from the **M2 Series** produced by **Leadshine**. This specific model is designed for high-precision motion control applications, typically paired with Leadshine’s ELP or EL7 series servo drives. --- ## 1. Technical Specifications The core electronic and physical characteristics are summarized in the table below: | Feature | Specification | | :--- | :--- | | **Motor Type** | AC Brushless Servo Motor | | **Rated Power** | 750W (0.75 kW) | | **Rated Torque** | 2.39 Nm | | **Peak Torque** | 7.1 Nm | | **Rated Speed** | 3000 RPM | | **Max Speed** | 5000 RPM | | **Encoder Type** | 23-bit Magnetic/Optical Absolute Encoder | | **Input Voltage** | 220 VAC | | **Protection Class** | IP65 (excluding shaft oil seal) | --- ## 2. Key Electronic Components ### A. 23-bit Absolute Encoder The most critical electronic part of this motor is the **23-bit multi-turn absolute encoder**. - **Resolution:** It provides $2^{23}$ (8,388,608) pulses per revolution. - **Function:** This allows for extremely smooth low-speed operation and eliminates the need for a "homing" sequence every time the machine is powered on, as the motor "remembers" its exact position. ### B. Permanent Magnet Synchronous Motor (PMSM) Internal Construction The motor utilizes high-coercivity rare-earth permanent magnets on the rotor. - **Stator Windings:** High-density copper windings designed for high thermal efficiency. - **Back EMF:** The internal electronics are optimized to provide a low Back-EMF constant, allowing the motor to reach high speeds (up to 5000 RPM) while maintaining stable torque. ### C. Connectors and Wiring The motor features two primary electronic interfaces: 1. **Power Connector:** A 4-pin interface (U, V, W, Ground) for the 220V AC input. 2. **Encoder Connector:** A multi-pin interface for high-speed serial communication (RS485/Differential) to send position data back to the drive. --- ## 3.
