The **M2RT-35-R2** is a specific model within the **M2RT series** of high-performance, compact rotary actuators or motorized stages (often associated with motion control systems like those from *Suruga Seiki* or similar precision engineering firms). Below is a breakdown of the electronic and technical components associated with this part. --- ### 1. Technical Specifications The M2RT series typically features high-resolution positioning capabilities. Here are the core electronic and mechanical parameters: | Component | Specification | Description | | :--- | :--- | :--- | | **Motor Type** | 2-Phase Stepping Motor | Provides precise incremental movement. | | **Step Angle** | 0.72° (Full Step) | Standard resolution for precision rotary stages. | | **Drive Voltage** | DC 24V (Typical) | standard industrial control voltage. | | **Current Rating** | ~0.75A to 1.5A per phase | Varies based on the specific driver used. | | **Sensor Type** | Photo-interrupter | Used for "Home" and "Limit" detection. | --- ### 2. Internal Electronic Parts #### A. Stepping Motor The heart of the unit is a **2-phase bipolar or unipolar stepping motor**. - **Function:** Converts electrical pulses into discrete mechanical rotations. - **Control:** Requires a dedicated stepper driver (like the DS102/103 series) to manage the pulse train and direction signals. #### B. Integrated Sensors To prevent mechanical over-travel and allow for system calibration, the unit includes: 1. **Home Sensor (Origin):** An optical sensor that identifies the "zero" position. 2. **Limit Sensors:** Prevent the stage from rotating beyond its mechanical bounds (usually present in ± degrees versions, though some M2RT models are continuous 360°). #### C. Wiring and Connector Pinout The unit typically uses a circular or D-sub connector. The wiring logic is generally split into two groups: * **Motor Leads:** 4 or 5 wires (depending on phase configuration). * **Sensor Leads:** VCC (+5V or +24V), GND, Home Signal, and Limit Signals. --- ### 3. Compatible Control System To operate the M2RT-35-R2, you need an external electronic ecosystem: ```mermaid graph LR A[PLC/Controller] --> B[Stepper Driver] B --> C[M2RT-35-R2 Motor] C --> D[Sensor Feedback] D --> A ``` 1. **Driver:** A micro-stepping driver is recommended to reduce vibration and increase resolution. 2. **Controller:** A pulse generator or PLC that outputs `Step` and `Direction` (Pulse/Dir) signals. --- ### 4. Key Application Areas * **Optics:** Precise alignment of lenses or mirrors. * **Semiconductor Inspection:** Rotating wafers for microscopic analysis. * **Automated Testing:** Position sensors or components at specific angles for calibration.
