Featured in this project is the control of a stepper motor with its speed, direction, and step size by sending some signals through the parallel port. The project provides better understanding and ...

A typical low-voltage variable-frequency drive. Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a ...
