The **EMMT-AS-60-M-LS-RMB** is a high-performance AC synchronous servo motor manufactured by **Festo**. It is designed for precise positioning and dynamic motion control in industrial automation. Below is a breakdown of its electronic and electromechanical specifications. ### 1. Key Technical Specifications The part number follows a specific nomenclature that defines its electronic characteristics: | Feature | Specification | Description | | :--- | :--- | :--- | | **Motor Type** | EMMT-AS | Brushless AC Synchronous Servo Motor | | **Flange Size** | 60 | 60mm frame size | | **Length** | M | Medium stack length | | **Winding** | LS | Low Speed / Specific winding impedance | | **Feedback** | R | Absolute Encoder (Multi-turn) | | **Brake** | MB | Integrated 24V DC Holding Brake | --- ### 2. Electronic Components & Feedback System #### **Digital Encoder (The "R" Suffix)** This motor utilizes a **digital absolute encoder** with a single-cable interface (Hiperface DSL or similar protocol). * **Type:** Multi-turn absolute. * **Function:** It remembers the motor's position even after power is disconnected, eliminating the need for "homing" runs. * **Electronic Nameplate:** Stores motor parameters (inductance, resistance, thermal limits) which the drive (e.g., CMMT-AS) reads automatically for "Plug and Play" configuration. #### **Holding Brake (The "MB" Suffix)** The motor includes an integrated electronic brake used to hold the load in place when the motor is de-energized. * **Voltage:** 24V DC (+10% / -15%). * **Purpose:** Safety and position holding; it is not designed to decelerate a moving load (dynamic braking). --- ### 3. Electrical Characteristics These values are critical for configuring the Servo Drive (VFD): | Parameter | Value (Approx.) | | :--- | :--- | | **Nominal Voltage** | 325 V DC / 565 V DC | | **Nominal Current** | ~2.1 A | | **Peak Current** | ~7.5 A | | **Nominal Power** | ~0.7 kW | | **Insulation Class** | F (up to 155°C) | --- ### 4. Connection Technology: OCP (One Cable Plug) A defining electronic feature of the EMMT-AS series is the **Single Cable Technology**. * **Hybrid Cable:** Power wires, brake wires, and digital feedback signals are all housed in one shielded cable. * **Benefit:** Reduces Electro-Magnetic Interference (EMI) issues compared to dual-cable systems and simplifies wiring. * **Connector:** Rotatable plug (M23) for flexible mounting.
