This Design Idea further develops a previous one integrating a stepper-motor driver in a CPLD (Reference 1). However, this idea integrates not only the driver, but also a simple one-axis stepper-motor ...

Motor controllers in general and especially closed-loop controllers have come a very long way in the past few years. Control flexibility, adaptability, and strategies that were only dreamed of or very ...

This application note describes how to implement an exact linear speed controller for stepper motors. The stepper motor is an electromagnetic device that converts digital pulses into mechanical shaft ...

It’s little secret that stepper motors are everywhere in FDM 3D printers, but there’s no real reason why you cannot take another type of DC motor like a brushless DC (BLDC) motor and use that instead.

En route to getting the off-the-peg DC-51 motor speed controller to better suit my small milling machine, I had a go at working out what the circuit is. Approx circuit of DC-51 motor speed controller ...
