This presentation empowers you with the knowledge to design effectively with stepper motors. It starts by demystifying their operation, covering full-step, half-step, and micro-stepping modes. You’ll explore the distinctions between unipolar and bipolar coils, along with various wiring configurations (4, 5, 6, and 8 wires).
Common challenges like resonance and lost steps are tackled, highlighting the importance of choosing the right decay rate (fast, slow, mixed). The presentation delves deeper, examining the dynamic relationships between motor current, drive voltage, speed, and torque under various conditions. Real-life applications come to life with illustrative oscilloscope waveforms.
