Köprü Bağlantılı Step Motor Sürücü L6203 L297

Cnc projesi hazırlanmış bir motor kontrol devresi temel elemanlar L6203 ve L297

Half bridge motors driver up to 2 amper / stage and this allowed me to do a bit of experience in the piloting of stepper motors. I even built a whole cnc funzionante.Sapevo to have suitable bridges to drive cnc small size and now it is time to move on to something more powerful. the bridge that I present here. It employs two integrated L6203 that each pilot phase and a L297 which is responsible for the translation of step and implements the chopper.
