The best motor is the one that meets the application requirements.  However, when both servo motors and stepper motors satisfy the basic requirements of a positioning application, it's important to have a deeper understanding of the two technologies to make an informed decision.

In this blog post,  I will summarize the differences between servo motor systems and stepper motor systems, then show how advances in stepper motor technology are closing the gap.
