modulator PWM

Recommended Posts

buna ziua. referitor la comanda motoarelor de curent continuu folosind module ce lucreaza cu arduino sau alte microcontrolere, stiu ca aceste module folosesc configuratia punte H sau semipute, iar factorul de umplere al PWM ului de la iesire se modifica printr-un modulator PWM. in foaia de catalog a modulului pe care il am eu, scrie ca acesta are generator PWM, cu 3 frecvente independente. modulatorul PWM si generatorul PWM sunt acelasi lucru? cu ambele se pot seta atat frecventa cat si factorul de umplere al semnalului?

Putem sa stim despre ce modul vorbesti?

Dupa cum scrie pe pagina shield-ului, poti modifica frecventa (80, 100, 200Hz) si factorul de umplere. 

 

Este pentru motoare mici, acei 0.9A sunt vârf. Mai mult un modul de invatat sa lucrezi cu el.
