This document discusses micro stepping mode for stepper motors. It begins with an introduction to stepper motors and their basic operation. It then discusses different types of stepper motors and their characteristics. Micro stepping mode is described as a technique that provides additional intermediate positions between poles by proportioning current in the motor windings, allowing for smooth rotation over a wide speed range with high positional resolution. The document outlines the mathematics and electronics behind micro stepping control and provides experimental results demonstrating reduced resonance and noise with precise position control.
