The **M2RS-60-R2/BL** refers to a specific configuration of a high-performance **M2RS Series AC Brushless Servo Motor**. These motors are commonly used in industrial automation, robotics, and CNC machinery where precise positioning and speed control are required. --- ### 1. General Specifications The part number can be broken down into specific electronic and mechanical characteristics: | Feature | Specification Details | | :--- | :--- | | **Series** | M2RS (Medium Inertia / High Response Series) | | **Flange Size** | 60mm | | **Rated Voltage** | 220V AC (Standard for R2 designation) | | **Brake Option** | "/BL" suffix indicates an **Electromagnetic Brake** included | | **Feedback System** | 17-bit or 23-bit Absolute/Incremental Encoder (typical for this series) | --- ### 2. Core Electronic Components #### A. Permanent Magnet Synchronous Motor (PMSM) At its core, this is a brushless motor utilizing high-energy neodymium magnets. Unlike DC motors, it has no brushes to wear out, reducing electronic noise and maintenance. #### B. Encoder (The Feedback Loop) The "brains" of the motor's positioning. The M2RS series typically utilizes: * **Resolution:** High-resolution optical or magnetic encoders. * **Signal Output:** High-speed serial communication to the servo drive. * **Function:** Provides real-time data on rotor position, speed, and direction. #### C. Electromagnetic Brake (/BL) The `/BL` designation confirms the presence of a 24V DC failsafe brake. * **Operation:** When power is removed, a spring mechanism clamps the shaft. * **Purpose:** Prevents "dropping" in vertical axis applications during power failure or emergency stops. --- ### 3. Connection Interface The motor features two primary electronic connection points: 1. **Power Connector:** * U, V, W phases for the AC drive output. * Ground (PE) connection. 2. **Encoder Connector:** * Provides power to the encoder (+5V). * Transmits differential signals (A, B, Z or Serial Data) to the controller. 3. **Brake Leads:** * Two additional wires (typically labeled B1, B2) for the 24V DC brake coil. --- ### 4. Technical Performance Table | Parameter | Estimated Value | | :--- | :--- | | **Rated Power** | 200W - 600W (depending on specific winding) | | **Rated Speed** | 3000 RPM | | **Max Speed** | 5000 - 6000 RPM | | **Insulation Class** | Class F (up to 155°C) | | **Protection Level** | IP65 (dust tight and water jet resistant) | ---
