## EMMT-AS-150-LR-HT-R2M: Electronic and Technical Specifications The **EMMT-AS-150-LR-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 following table summarizes the primary electronic and physical characteristics of this specific model: | Parameter | Value / Specification | | :--- | :--- | | **Motor Type** | AC Synchronous Servo Motor | | **Flange Size** | 150 mm | | **Rated Voltage** | 565 V DC (Bus Voltage) | | **Nominal Torque** | ~ 27.0 Nm (Depending on cooling/mounting) | | **Peak Torque** | ~ 85.0 Nm | | **Rated Speed** | 2,500 - 3,000 RPM | | **Winding Type** | High Torque (HT) | | **Feedback System** | Multi-turn Absolute Encoder (R2M) | | **Connection Technology** | Single Cable Solution (OCP) | --- ### 2. Breakdown of Electronic Parts & Features #### A. Winding and Power (HT - High Torque) The "HT" designation indicates a specific winding configuration optimized for **High Torque** density. * **Neodymium Magnets:** Uses high-grade permanent magnets on the rotor to ensure high efficiency and low inertia. * **Insulation Class:** Class 155 (F), providing thermal durability for demanding duty cycles. #### B. Feedback System (R2M - Multi-turn Encoder) The electronic "eyes" of the motor consist of a high-resolution encoder: * **Type:** Digital absolute encoder. * **Multi-turn:** It tracks the exact position of the motor shaft over multiple revolutions (usually up to 4096 turns), meaning the machine does not require "homing" after a power loss. * **Protocol:** Uses a digital interface (typically Hiperface DSL or similar) integrated into the power cable. #### C. Connection System (Single Cable Technology) Unlike traditional motors that require separate cables for power and feedback, this model uses a **Single Cable Solution**: * **Electronics Integration:** The encoder signal is modulated onto the power conductors or carried via extra shielded pairs within the same jacket. * **Plug Type:** M23 or M40 industrial circular connector, reducing wiring complexity and potential points of failure. #### D. Integrated Holding Brake (Optional/Standard) Depending on the specific sub-configuration (often implied in the AS series): * **Electronic Control:** The brake is 24V DC operated. It is a "fail-safe" type, meaning it locks the shaft when power is removed to prevent the axis from falling under gravity. --- ### 3. Usage and Compatibility To operate this motor, it must be paired with a compatible servo drive. ```yaml Recommended Drive: Festo CMMT-AS-C12-11P3 (High Power Series) Communication: EtherCAT, PROFINET, or EtherNet/IP Function: Field Oriented Control (FOC) for precise current regulation ```
