The part number **08KENG3EAM-R** corresponds to a high-performance **Brushless DC (BLDC) Motor**, specifically a **NEMA 8 size Integrated Stepper/Servo Motor**. These components are frequently used in precision motion control for medical devices, robotics, and automated laboratory equipment. --- ## 1. Technical Specifications The "08" in the part number signifies the **NEMA 8** frame size (approximately 20mm x 20mm), making it one of the smallest industrial-grade motion control units available. | Feature | Specification | | :--- | :--- | | **Frame Size** | NEMA 8 (20mm) | | **Motor Type** | Brushless DC / Stepper | | **Input Voltage** | Typically 12V - 24V DC | | **Step Angle** | 1.8° (200 steps per revolution) | | **Integration** | Integrated Controller/Driver | | **RoHS Status** | Compliant (-R suffix) | --- ## 2. Key Component Breakdown The assembly is "integrated," meaning several electronic parts are combined into a single housing: ### A. The BLDC/Stepper Motor The core is a high-torque-to-size permanent magnet motor. It uses electromagnetic coils to rotate the shaft in precise increments. ### B. Integrated Driver (The Controller) Unlike standard motors that require an external control box, this unit contains a PCB (Printed Circuit Board) mounted to the back. * **Microstepping Driver:** Divides full steps into smaller micro-steps for smoother motion. * **H-Bridge Circuitry:** Manages the flow of current to the motor phases. ### C. Feedback Mechanism (Encoder) The "E" in the part sequence often denotes an **Encoder**. * **Function:** It provides closed-loop feedback, allowing the system to know the exact position of the shaft. * **Benefit:** Prevents "stalling" or lost steps, which is critical in precision medical applications. --- ## 3. Typical Applications Due to its miniature size and integrated electronics, the **08KENG3EAM-R** is found in: * **Automated Pipetting:** Moving small fluid volumes in labs. * **CCTV Pan/Tilt:** Precise camera positioning. * **3D Printing/Scanning:** Miniature extrusion or sensor positioning. * **Valve Control:** Opening and closing micro-valves in chemical processing. --- ## 4. Hardware Connectivity The motor typically features a multi-pin connector (often JST or Molex style) to handle: 1. **Power:** Positive and Ground (VDC). 2. **Communication:** Pulse/Direction signals or Serial communication (RS-485/CAN). 3. **Error Output:** Signals to the main PLC if the motor jams.
