The **15011-R2** is a specialized electronic component, most commonly recognized as a **Stepper Motor** or a **Linear Actuator** (specifically manufactured by companies like **Haydon Kerk Pittman**, a brand of AMETEK). Below is a detailed breakdown of its electronic and mechanical specifications. --- ## 1. Component Overview The 15011-R2 belongs to the **Can-Stack** family of linear actuators. It converts rotary motion into linear motion through a threaded nut and leadscrew system integrated directly into the motor. ### Technical Specifications Table | Feature | Description | | :--- | :--- | | **Motor Type** | Bipolar or Unipolar Stepper (Model dependent) | | **Frame Size** | Series 15000 (Ø 15mm / 0.6 inch) | | **Resolution** | Typically 0.02 mm to 0.10 mm per step | | **Operating Voltage** | Usually 5V or 12V DC | | **Current per Phase** | ~0.2A to 0.4A (variable by winding) | | **Linear Travel** | Determined by leadscrew length | --- ## 2. Key Electronic Parts & Construction ### Internal Windings The "R2" designation often refers to a specific winding configuration or a revision of the internal coils. These coils are made of high-temperature magnet wire wrapped around a plastic bobbin, creating the electromagnetic poles required to turn the rotor. ### The Rotor (Permanent Magnet) The center of the motor contains a permanent magnet rotor. In the 15011-R2, the rotor is hollowed out and contains a **threaded nut** (often made of engineered thermoplastics like Acetal/Delrin). ### Leadscrew The leadscrew passes through the motor. When the electronic pulses energize the coils, the rotor spins, and the internal threads push the leadscrew in or out. --- ## 3. Wiring and Control To operate the 15011-R2, you need an electronic **Stepper Driver**. * **Bipolar Configuration (4 wires):** Requires an H-Bridge circuit (like an A4988 or L298N) to reverse current flow through the coils. * **Unipolar Configuration (5-6 wires):** Can be driven with simpler Darlington Transistor arrays (like the ULN2003). ### Step Sequence logic | Step | Phase A | Phase B | | :--- | :--- | :--- | | 1 | HIGH | LOW | | 2 | LOW | HIGH | | 3 | LOW | LOW | | 4 | HIGH | HIGH | --- ## 4. Typical Applications Because of its small size (15mm diameter) and precise movement, the 15011-R2 is found in: 1. **Medical Devices:** Small pumps and liquid handling. 2. **Optics:** Camera lens focusing or aperture control. 3. **Telecommunications:** Fine-tuning of microwave filters. 4. **Robotics:** Micro-actuators for grippers. ---
