When it comes to motion control, stepper motors<\/strong> and servo motors<\/strong> are two of the most common options you’ll run into. But they work in very different ways\u2014and choosing the right one depends on what your project needs.<\/p>

What Is a Stepper Motor?<\/h2>

\"Diagram

A stepper motor<\/strong> is a type of motor that moves in small, equal steps. It doesn\u2019t need a feedback system to know its position. This is called open-loop control<\/strong>. You simply send signals that tell it how many steps to move\u2014and it does it. That makes it ideal for applications where position and speed are predictable and repeatable.<\/p>
