The **EMMT-AS-60-M-LS-RMY** is a high-performance AC synchronous servo motor manufactured by **Festo**. It is designed for precise positioning and dynamic movement in industrial automation. Below is the breakdown of its electronic and electromechanical specifications. ### 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Motor Type** | Brushless AC Synchronous Servo Motor | | **Flange Size** | 60 mm | | **Output Power** | Approx. 0.45 kW to 0.7 kW (Load dependent) | | **Nominal Torque** | ~1.3 Nm to 2.2 Nm | | **Nominal Speed** | 3000 - 6000 RPM | | **Voltage Class** | 325V DC / 565V DC (Bus Voltage) | | **Insulation Class** | F (Up to 155°C) | | **Degree of Protection** | IP67 (Housing and Plug connection) | --- ### 2. Feedback System (The "RMY" Suffix) The electronics inside this specific model utilize a sophisticated feedback system: * **Encoder Type:** Absolute Encoder, Multi-turn. * **Protocol:** **Hiperface DSL®** (Digital Servo Link). * **Benefit:** This is a "One Cable Technology" (OCT) system. Both the power supply to the motor and the digital feedback signals are transmitted through a single hybrid cable, reducing wiring complexity and electromagnetic interference (EMI). * **Resolution:** Typically 18-bit to 20-bit, allowing for extremely high precision in angular positioning. --- ### 3. Electrical Connections The motor features a single integrated plug-in connector that handles three distinct electronic circuits: 1. **Power Circuit:** * Phases: U, V, W. * Protective Earth (PE). 2. **Brake Circuit (Optional/Model dependent):** * The "M" in the code typically signifies a holding brake is included. * Operating Voltage: 24V DC. 3. **Communication/Encoder:** * Digital interface for real-time position, speed, and temperature data. --- ### 4. Part Number Breakdown The nomenclature provides specific details about the electronic and physical build: | Code | Meaning | | :--- | :--- | | **EMMT-AS** | Brushless Servo Motor, AC Synchronous | | **60** | Flange size (60mm) | | **M** | Length (Medium) | | **LS** | Connection type (Liquid/Simple/One-cable) | | **R** | Encoder type (Absolute, Multi-turn) | | **M** | Integrated holding brake | | **Y** | Standardized output shaft | --- ### 5. Integration with Drive Controllers This motor is electronically optimized for use with the **Festo CMMT-AS** series of servo drives. Because of the digital feedback (RMY), the drive can automatically read the "Electronic Rating Plate" of the motor, meaning the drive auto-configures the motor's parameters (current limits, pole pairs, etc.) upon connection.
