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.

Motors must accelerate loads while overcoming system friction and gravity without overheating. Here, we outline a step-by-step process for picking a motor size that’s up to the ...

How optical rotary encoders can provide real-time motion feedback on motion applications using stepper motor-driven linear actuators.
