Generates digital step and direction pulses. Common controllers include microcontrollers (like Arduino), PLCs, or dedicated CNC boards.
Most industrial and hobbyist drivers use a simple two- or three-wire logic interface: Stepper Motors Basics: Types, Uses, and Working Principles Stepper Motor Control
—allowing for exact positioning without the need for external feedback sensors. A typical control system consists of three main parts: Generates digital step and direction pulses
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. Stepper Motor Control
