The **EMMT-AS-80-S-LS-RMYB** is a high-performance AC synchronous servo motor manufactured by **Festo**. It is part of the EMMT-AS series, designed for demanding industrial automation tasks requiring high dynamic response and precision. Below is a breakdown of its technical and electronic specifications. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Motor Type** | AC Synchronous Servo Motor | | **Flange Size** | 80 mm | | **Length** | S (Short) | | **Output Power** | ~1.1 kW (Nominal) | | **Nominal Torque** | 2.6 Nm | | **Peak Torque** | 9.5 Nm | | **Nominal Speed** | 3000 - 6000 RPM (depending on voltage) | | **Protection Class** | IP67 (Housing and Connection) | --- ### 2. Electronic Component Breakdown The "RMYB" suffix in the model code provides specific details about the electronic configuration: #### A. Encoder System (Electronic Feedback) * **Type:** Absolute Encoder, Multi-turn. * **Protocol:** **Hiperface DSL** (Digital Servo Link). * **Function:** This is a "single-cable" solution. It communicates position data digitally to the motor controller. Because it is **Multi-turn**, it remembers the absolute position of the motor even after power-off, eliminating the need for a homing run. #### B. Connection Interface * **Single Cable Technology:** Unlike traditional motors that require one cable for power and one for feedback, this motor uses one integrated plug for both. * **Connector Type:** M23 hybrid connector. This reduces wiring complexity and space requirements in cable chains. #### C. Integrated Holding Brake * **Voltage:** 24V DC. * **Function:** The "B" in the suffix indicates an integrated spring-loaded holding brake. This is an electronic safety feature that locks the shaft in place when power is removed, preventing the load from falling in vertical applications. --- ### 3. Winding and Power Electronics The motor is a brushless design (brushless DC/AC), which means: * **Electronic Commutation:** The motor requires a servo drive (like the Festo **CMMT-AS**) to switch the current between the windings based on the encoder feedback. * **Winding Insulation:** Class 155 (F), allowing for high operating temperatures without damaging the internal copper coils. --- ### 4.
