So he started to wonder if he could skip the controller entirely and connect the stepper motor directly to the digital pins of an Arduino.

How to Control a Stepper Motor Using a Computer. Stepper motors produce accurate, computer-controlled motion for applications such as robotic arms and paper-feed mechanisms for printers.

Rather than having the host Pi communicate directly with the stepper drivers, the 3+Pi features an onboard STM32F302CBT6 that handles the actual motor control.

The ongoing advancements in stepper motor technology also highlight important trends for automation engineers, particularly in energy efficiency, customization and integration. Modern stepper motors ...

The CMMS-ST controller differentiates itself from conventional controllers by eliminating resonance, heating, and loss of step—performance issues inherent in stepper motor systems, says the vendor. In ...

Advanced internal current sensing provides better current regulation in bipolar stepper motor drivers, which improves the quality of motion.
