Acts as the power interface. It receives low-power pulses from the controller and switches high-power current to the motor's windings in the correct sequence.

The actuator that converts the electrical pulses into mechanical rotation. Standard Control Interfaces Stepper Motor Control

—allowing for exact positioning without the need for external feedback sensors. A typical control system consists of three main parts: Acts as the power interface

Most industrial and hobbyist drivers use a simple two- or three-wire logic interface: Stepper Motors Basics: Types, Uses, and Working Principles or dedicated CNC boards.

Generates digital step and direction pulses. Common controllers include microcontrollers (like Arduino), PLCs, or dedicated CNC boards.
