The **EMMT-AS-150-L-HT-R2S** 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 detailed breakdown of its electronic and electromechanical specifications. --- ### 1. Core Technical Specifications The following table highlights the primary electrical ratings for this specific motor model: | Parameter | Specification | | :--- | :--- | | **Motor Type** | AC Synchronous Servo Motor | | **Nominal Voltage** | 565 V DC | | **Nominal Current** | 13.1 A | | **Peak Current** | 52 A | | **Nominal Power** | 6,550 W (approx. 6.5 kW) | | **Nominal Torque** | 20.9 Nm | | **Peak Torque** | 77.0 Nm | | **Nominal Speed** | 3,000 rpm | | **Max. Speed** | 4,200 rpm | --- ### 2. Key Electronic Components #### A. Feedback System (Encoder) The "R2S" suffix in the part number indicates the feedback type: * **Type:** 2-wire digital encoder (Single-turn). * **Interface:** **HIPERFACE DSL®**. This is a digital protocol that allows for "One Cable Technology," where both power and encoder data travel over a single hybrid cable, reducing wiring complexity and electromagnetic interference (EMI). #### B. Integrated Temperature Sensing The motor includes an integrated temperature sensor (likely a **Pt1000** or similar thermistor). * **Function:** It monitors the winding temperature and transmits this data via the HIPERFACE DSL digital link back to the servo drive (CMMT-AS). * **Protection:** Prevents thermal overload by triggering a shutdown if the motor exceeds its insulation class limits (Class 155 / F). #### C. Winding and Insulation * **Insulation Class:** Class 155 (F), rated for high-temperature environments. * **Winding Configuration:** Optimized for high torque density and low cogging torque, ensuring smooth motion at low speeds. --- ### 3. Connection and Protection * **Connector Type:** M23 Hybrid plug. This connector integrates the 3-phase power, the protective earth (PE), the holding brake (optional), and the digital feedback pins. * **IP Rating:** **IP65** (with shaft seal). This indicates the electronic internals are protected against dust and water jets. * **Brake (HT variant):** The "HT" indicates high torque, and this specific model usually includes a 24V DC holding brake to prevent the load from dropping when power is removed. --- ### 4.
