The **EMMT-AS-60-M-LS-RMYB** is a high-performance AC synchronous servo motor manufactured by **Festo**. It is designed for precise positioning tasks and dynamic motion control within industrial automation environments. --- ### 1. Part Number Breakdown To understand the electronic and mechanical specifications, we can decode the nomenclature: | Code | Specification | Description | | :--- | :--- | :--- | | **EMMT-AS** | Series | Brushless AC Synchronous Servo Motor | | **60** | Flange Size | 60 mm motor frame size | | **M** | Length | Medium stack length (torque capacity) | | **LS** | Connection | Single-cable plug (Hybrid) | | **R** | Encoder Type | Absolute, Multi-turn (EnDat 2.2) | | **M** | Output Shaft | Smooth shaft (no keyway) | | **Y** | Brake | Integrated holding brake | | **B** | Standard | Generation/Internal revision | --- ### 2. Key Electronic Features #### A. Digital Encoder (Feedback System) * **Type:** Absolute Multi-turn (EnDat 2.2 protocol). * **Function:** It tracks the exact position of the motor shaft. Because it is "Multi-turn," the motor remembers its position even after a power cycle, eliminating the need for a homing run. * **Electronic Nameplate:** The motor contains an internal memory chip that stores its parameters (current limits, torque constants, etc.). When connected to a Festo CMMT-AS driver, these parameters are uploaded automatically. #### B. Integrated Holding Brake * **Function:** An electromechanical brake used to hold the load in place when the motor is de-energized. * **Operation:** It is a "fail-safe" brake (closed when power is off). It requires a DC voltage (typically 24V) to release. #### C. Single-Cable Technology (Hybrid Connection) * **Wiring:** Unlike traditional motors that use one cable for power and one for feedback, this model uses a single "Hybrid" cable. * **Benefit:** Reduces wiring complexity, saves space in cable chains, and minimizes electromagnetic interference (EMI) risks by using standardized shielding. --- ### 3. Technical Specifications (Electronic/Performance) | Parameter | Value (Typical) | | :--- | :--- | | **Nominal Voltage** | 325 V DC / 565 V DC | | **Nominal Torque** | ~ 1.3 to 1.5 Nm | | **Peak Torque** | ~ 4.5 Nm | | **Nominal Speed** | 3000 - 6000 RPM (depending on voltage) | | **Insulation Class** | F (up to 155°C) | | **Protection Class** | IP67 (Motor housing and plug) | --- ### 4. Compatible Drive Systems This motor is electronically optimized for the **Festo CMMT-AS** series of servo drives. Communication is handled via the digital feedback interface, allowing for high-speed synchronization over industrial Ethernet protocols like: * EtherCAT * PROFINET * EtherNet/IP ---
