The **EMMT-AS-150-LK-HT-R2M** is a high-performance AC synchronous servo motor manufactured by **Festo**. It is designed for precise positioning and dynamic movement in industrial automation. --- ### 1. Key Technical Specifications The part number provides a coded description of its electronic and mechanical capabilities: | Feature | Specification | | :--- | :--- | | **Motor Type** | AC Synchronous Servo Motor | | **Flange Size** | 150 mm | | **Feedback System** | Absolute Encoder, Multi-turn (R2) | | **Connection Technology** | M23 Hybrid Plug (Single Cable Solution) | | **Protection Class** | IP67 (Housing and Plug Connection) | | **Nominal Torque** | ~ 25 Nm to 35 Nm (Depending on drive configuration) | | **Peak Torque** | Significant headroom for high acceleration | --- ### 2. Electronic Components & Features #### A. Feedback System (Digital Encoder) The **"R2"** designation indicates a high-resolution **Multi-turn Absolute Encoder**. * **Electronic Memory:** It stores position data even when the power is disconnected, eliminating the need for a "homing" run upon startup. * **Digital Interface:** Likely uses a modern protocol (like Hiperface DSL or EnDat) to transmit position, speed, and temperature data over the same cable as the power. #### B. Single Cable Technology (Hybrid Connection) The **"M"** in the suffix refers to the Single Cable solution using an **M23 Hybrid connector**. * **Integration:** Power for the motor phases, the 24V holding brake (if equipped), and the digital encoder signals are all carried in one shielded cable. * **EMC Protection:** The motor electronics are designed to minimize Electromagnetic Interference (EMI) through advanced shielding within the hybrid connector. #### C. Thermal Management The **"HT"** designation often refers to High Torque or specific thermal characteristics. * **NTC/PTC Sensors:** Internally, the motor contains temperature sensors integrated into the windings. These sensors send real-time data to the motor controller (Servo Drive) to prevent overheating and thermal damage. #### D. Winding & Magnetics * **Permanent Magnets:** Uses high-energy rare-earth magnets on the rotor for high power density. * **Low Cogging:** The electronic design of the stator slots is optimized to reduce "cogging torque," ensuring smooth rotation even at very low speeds. --- ### 3. System Integration This motor is typically paired with the **Festo CMMT-AS** series servo drives. The electronic "Electronic Rating Plate" within the motor allows the drive to automatically identify the motor parameters (plug-and-work). ---
