Versatile Solid-state stepper motor Controllers
Four main parts are discernible, namely: a stepper motor, a stepper motor drive (or power circuit), a stepper motor controller, and an optional opto-coupler (or opto-isolator) between the drive and the controller. The solid-state switches comprising the drive are logic level operated. … Get Content Here
