Based on technical specifications, the **17TG-76-R** typically refers to a high-performance **Step Motor (Stepper Motor)**, often associated with manufacturers like Moons' or similar industrial automation brands. It is designed for precision motion control. --- ### 1. Key Technical Specifications The "17" in the prefix generally indicates a **NEMA 17** frame size, which is the standard for 3D printers and small CNC machines. | Feature | Specification (Typical) | | :--- | :--- | | **Frame Size** | NEMA 17 (42mm x 42mm) | | **Step Angle** | 1.8° (200 Steps per revolution) | | **Phase Current** | Approx. 1.0A - 1.5A | | **Winding Type** | Bipolar | | **Termination** | Connector or Flying Leads | | **Compliance** | RoHS (Indicated by the "R" suffix) | --- ### 2. Internal Electronic Components While the motor is an electromechanical device, its internal "electronic" parts consist of the following: #### A. Stator Windings * **Composition:** Copper coils wound around the stator poles. * **Function:** When energized by an external driver, these coils create an electromagnetic field that pulls the rotor. #### B. Rotor (Permanent Magnet) * **Composition:** Typically a hybrid construction using a permanent magnet sandwiched between two toothed iron caps. * **Function:** Provides the magnetic poles that interact with the stator to create torque. #### C. Connector Interface * **Type:** JST or similar pin headers. * **Configuration:** Usually 4 pins for bipolar operation (A+, A-, B+, B-). --- ### 3. Connection Diagram (Bipolar) To operate this part, it must be connected to a stepper driver (like an A4988 or TMC2209). ```text Stepper Driver 17TG-76-R Motor [ Phase A+ ] <----------> [ Coil 1 Start ] [ Phase A- ] <----------> [ Coil 1 End ] [ Phase B+ ] <----------> [ Coil 2 Start ] [ Phase B- ] <----------> [ Coil 2 End ] ``` --- ### 4. Typical Applications * **3D Printing:** Used for X, Y, or Z-axis movement. * **Medical Equipment:** Precision liquid handling or scanning. * **Office Automation:** Paper feed mechanisms in high-end printers. * **Robotics:** Small joint actuators or grippers. ---
