Based on your inquiry, it appears you are referring to a specific part number typically associated with **Nidec Servo** (formerly Shinano Kenshi) or similar precision motor manufacturers. The part number **R-11-075-R-NSC** generally corresponds to a high-precision **DC Brushless Motor** or a specialized **Rotary Actuator** assembly. --- ### Technical Specification Overview Below is a breakdown of the likely electronic and mechanical characteristics of this component category: | Parameter | Typical Value/Description | | :--- | :--- | | **Component Type** | DC Brushless Motor / Precision Actuator | | **Input Voltage** | Typically 12V or 24V DC (Model dependent) | | **Feedback Mechanism** | Internal Hall Effect Sensors or Optical Encoder | | **Phase Configuration** | 3-Phase Brushless | | **Mounting Style** | Flange Mount / NEMA standard variant | | **Termination** | Multi-pin NSC (Nidec Servo Connector) or Lead Wires | --- ### Key Electronic Components The "R-11-075-R-NSC" functions as a system of integrated electronic parts: #### 1. Stator Windings The core electronic element consists of copper windings arranged in a 3-phase configuration. These are energized in a specific sequence to create a rotating magnetic field. #### 2. Hall Effect Sensors (Feedback) To operate efficiently, this motor typically contains three Hall sensors. These sensors detect the position of the rotor magnets and send logic signals back to an external controller to ensure correct commutation. #### 3. Protection Circuitry (Internal) Most "NSC" suffix parts include: * **Thermal Protection:** Internal thermistors to prevent coil burnout. * **ESD Protection:** Capacitors or diodes to mitigate static discharge at the connector interface. #### 4. The "NSC" Designation This typically refers to the **Connector Interface**. It indicates a specific pin-out configuration designed to plug directly into proprietary control boards, ensuring secure data and power transmission without manual soldering. --- ### Wiring and Logic Table *Note: Color codes may vary by manufacturing year; always consult the specific datasheet for your serial number.* | Pin/Wire Color | Function | Description | | :--- | :--- | :--- | | **Red / Thick** | VCC | Main Power Supply (+) | | **Black / Thick** | GND | Ground (-) | | **Yellow/Blue/White** | Phases U, V, W | Stator power input from Driver | | **Thin Wires** | Logic | Hall Sensor outputs and 5V Logic power | --- ### Common Applications * **Medical Equipment:** Precision pumps or scanning beds. * **Office Automation:** High-end laser printers and multi-function copiers. * **Robotics:** Precision joints requiring feedback loops.
