I am as a beginner in electronics contemplating how to build a motor driver for a stepper motor.
From what I have read, the more sophisticated drivers will have a feature known as micro stepping which basically means that instead of switching winding current on and of per phase (full step) or adding a layer by alsow reversing polarity (half step), the voltage is adjusted in levels where up to 8 levels is common.
Further the state of the art with this technology talks of how an even and artifact-free sinusoidal voltage signal is the most important to get a smooth running and efficient motor with high precision movement.
It occurred to me that this resembles the goals of audio equipment as well. So my question is thus: Would it be feasible to use a speaker driver to drive a stepper motor? Why/why not? What are potential caveats that I must be aware of?
