The **17TS-45-R** typically refers to a high-precision, miniature **Stepping Motor** (often of the Permanent Magnet or Hybrid variety) commonly used in small electronics, medical devices, and office automation. Below is a detailed breakdown of its electronic and mechanical specifications. --- ### 1. General Specifications The "17TS" series usually follows the NEMA 17 mounting footprint but is optimized for specific torque-to-size ratios. | Parameter | Typical Value | | :--- | :--- | | **Motor Type** | Bipolar Stepper | | **Step Angle** | 1.8° (200 steps per revolution) | | **Phase Voltage** | 3.0V - 12V DC (Driver dependent) | | **Rated Current** | 1.0A - 1.5A per phase | | **Resistance** | 2.0 Ω - 5.0 Ω (approx) | | **Inductance** | 3.5 mH - 5.0 mH | | **Holding Torque** | 40 - 50 N.cm | --- ### 2. Internal Electronic Components The motor operates on electromagnetic induction principles involving the following parts: * **Stator Windings:** Comprised of copper coils. The "R" in the part number often signifies a specific winding resistance or RoHs compliance. * **Rotor:** A permanent magnet (often Neodymium) attached to the shaft. * **Phase Configuration:** Usually a **4-wire Bipolar** setup. This requires an H-Bridge driver to reverse the polarity of the current to step the motor. --- ### 3. Wiring Diagram (Bipolar) The electronic connection usually consists of two independent phases (A and B). | Wire Color (Common) | Phase | Description | | :--- | :--- | :--- | | **Black** | A+ | Phase 1 Start | | **Green** | A- | Phase 1 End | | **Red** | B+ | Phase 2 Start | | **Blue** | B- | Phase 2 End | --- ### 4. Implementation Requirements To drive this electronic part effectively, the following logic and power components are required: 1. **Stepper Driver:** (e.g., A4988, DRV8825, or TMC2209) to manage the current limits and micro-stepping. 2. **Controller:** (e.g., Arduino, ESP32, or PLC) to provide step and direction signals. 3. **Power Supply:** A DC source higher than the rated voltage (typically 12V-24V) to overcome back-EMF during high-speed rotation. --- ### 5. Key Applications * **3D Printers:** Used for X/Y/Z axis movement. * **Medical Pumps:** Precise dosing and fluid control. * **CCTV Cameras:** Pan and tilt mechanisms. * **Robotics:** Small-scale actuators and grippers. ---
