The **48SV2-RV5SRR** is a specific model within the **SV2 Series** of AC Servo Motors, typically manufactured by companies like **Sanyo Denki** (SanMotion). These parts are engineered for high-precision motion control in industrial automation. --- ### 1. Technical Specifications Breakdown The alphanumeric code represents the mechanical and electrical characteristics of the motor: | Feature | Specification | Description | | :--- | :--- | :--- | | **Series** | SV2 Series | High-performance AC Servo system. | | **Frame Size** | 48mm | The square flange size of the motor. | | **Voltage Input** | AC 200V / 230V | Standard industrial power requirement. | | **Encoder Type** | Incremental / Absolute | High-resolution feedback for positioning. | | **Brake Option** | Integrated | "SRR" variants often indicate specific shaft/brake configurations. | --- ### 2. Key Electronic Components The "Electronic Parts" of this assembly consist of three main functional blocks: #### A. The Stator and Rotor (The Power Section) * **Stator Windings:** Three-phase copper windings that create a rotating magnetic field when energized by the Servo Drive. * **Permanent Magnets:** High-coercivity magnets (usually Neodymium) mounted on the rotor to ensure high torque-to-inertia ratios. #### B. Feedback System (The Encoder) This is the most critical electronic component located at the rear of the motor: * **Optical/Magnetic Disk:** Rotates with the shaft to track position. * **Processing Circuitry:** Converts physical rotation into digital pulses (Pulse/Rev) or serial data sent to the drive. * **Resolution:** Typically ranges from 17-bit to 24-bit, allowing for sub-micron positioning accuracy. #### C. Thermal Protection * **Thermistor/PTC:** An internal sensor embedded in the windings that increases resistance as temperature rises, signaling the drive to shut down if overheating occurs. --- ### 3. Connection Interface The motor features specific electronic connectors for integration: 1. **Power Connector:** 4-pin (U, V, W, Ground) for the 3-phase AC supply. 2. **Encoder Connector:** Multi-pin connector for power (5V/12V), Signal (A, B, Z phases), and serial communication. 3. **Brake Leads (If applicable):** 2-pin connection to release the electromagnetic holding brake. --- ### 4. Typical Applications * **Semiconductor Manufacturing:** For precise wafer handling. * **CNC Machinery:** For high-speed axis movement. * **Robotic Arms:** Providing the joint torque and positioning feedback. ---
