The **4M113N-R** is a specific part number typically associated with **Step-Servo Motors** (Integrated Stepper Motors) or specialized motor driver components, most notably from manufacturers like **Leadshine** or similar industrial automation brands. Below is a technical breakdown of its characteristics and electronic specifications. --- ### 1. General Overview The 4M113N-R belongs to a category of **integrated motion control components**. Unlike a standard stepper motor that requires a separate external drive, integrated units combine the motor, encoder, and drive electronics into a single housing. ### 2. Technical Specifications | Feature | Description | | :--- | :--- | | **Type** | NEMA High-Torque Stepper / Step-Servo | | **Input Voltage** | Typically 18 - 80 VDC or 24 - 70 VDC | | **Phase** | 2-Phase or 3-Phase (Model dependent) | | **Step Angle** | 1.8° (Standard) | | **Communication** | Pulse/Direction (PUL/DIR) or RS485/Modbus | | **Feedback** | Integrated Incremental Encoder (often 1000 or 2500 lines) | ### 3. Key Electronic Components The "R" suffix often denotes specific revisions or communication protocols (like RS485). The internal electronics consist of: * **Integrated Driver:** Uses MOSFET or IGBT power stages to control current flow to the motor windings. * **Closed-Loop Logic:** Uses the encoder signal to prevent "lost steps," a common issue in open-loop steppers. * **Digital Signal Processor (DSP):** An onboard microchip that calculates motion profiles and handles PID current control to reduce heat and noise. * **Protection Circuits:** Built-in safeguards for: * Over-voltage * Over-current * Position following error (Tracking error) ### 4. Typical Applications Because of its high precision and integrated nature, the 4M113N-R is used in: 1. **CNC Machinery:** For precise axis movement. 2. **3D Printers & Laser Cutters:** Where space is limited and external drivers are bulky. 3. **Medical Equipment:** Requiring low noise and high reliability. 4. **Automated Assembly Lines:** For high-speed pick-and-place operations. --- ### 5. Wiring Pinout (General) Most units in this series use a standardized connector layout: ```yaml Pin 1: V+ (Power Supply Positive) Pin 2: GND (Power Supply Ground) Pin 3: PUL+ (Pulse Signal) Pin 4: DIR+ (Direction Signal) Pin 5: ENA+ (Enable Signal) Pin 6: Alarm Output (Feedback to PLC) ``` ---
