The **EMMT-AS-80-S-HS-RMB** 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 a breakdown of its technical specifications and electronic components. ### 1. Technical Specifications Table | Feature | Specification | | :--- | :--- | | **Motor Type** | AC Synchronous Servo Motor | | **Flange Size** | 80 mm | | **Output Power** | ~1.1 kW (Nominal) | | **Nominal Torque** | 2.50 Nm | | **Peak Torque** | 7.80 Nm | | **Max. Speed** | 6,000 RPM | | **Insulation Class** | F (up to 155°C) | | **Protection Class** | IP67 (Housing), IP65 (Shaft) | --- ### 2. Key Electronic & Mechanical Components #### A. Winding and Magnetic Circuit * **Permanent Magnet Technology:** The rotor utilizes high-energy permanent magnets to achieve high power density and low inertia. * **3-Phase Stator:** The stator consists of copper windings designed for high-voltage AC input (typically 230V - 480V depending on the controller pairing). #### B. Encoder System (Feedback) The motor uses a high-resolution feedback system to communicate position and speed back to the motor controller (e.g., Festo CMMT-AS). * **Type:** Absolute Encoder, Multi-turn. * **Technology:** Hipersat / Digital (Single-cable technology). * **Benefit:** It remembers the position even after a power cycle, eliminating the need for a homing run. #### C. Integrated Brake * **Part Code "B":** The "B" in the part number indicates an integrated **Holding Brake**. * **Operation:** It is a spring-applied brake that engages when power is removed, preventing the load from falling or moving during an E-stop or power failure. #### D. Connectivity (OCP) * **One-Cable Technology:** This motor supports "One Cable Connection" (OCC). Power, encoder signals, and brake control are all carried in a single hybrid cable. * **Digital Link:** Uses a robust digital communication protocol to reduce electromagnetic interference (EMI) issues commonly found in traditional separate-cable systems. --- ### 3. Electronic Protection & Monitoring The motor includes internal electronic safeguards to prevent failure: * **Temperature Sensor:** Integrated **Pt1000** or NTC thermistor that monitors winding temperature. If the motor exceeds safe thermal limits, the drive controller triggers a fault to prevent burnout. * **Electronic Nameplate:** The encoder stores motor data (torque constants, inertia, serial number). When connected to a Festo CMMT drive, the drive automatically reads these parameters for "Plug and Work" commissioning. ---
