STM32F PMSM motor driver
#18
Naravno drugar, samo ne zaboravi da evaluation board skoro nikada nije i konačno
rešenje za primenu u praksi. Tu se uvek koriste IC kola koje ta firma i proizvodi
bez obzira što konkuretske firme možda imaju i bolju opciju.

Evo upravo gledam dokument od tih STEVAL invertera,
nigde ne vidim za koje nazivne napone motora je to predvidjeno, kolike induktivnosti namotaja itd ...
Znači , dali su samo podatak o graničnim vrednostima IGBT modula !?

Ako tvoji motori imaju nazivni radni napoon od 150V, onda je previše kačiti ih na DC bus od +325V !
Promenom duty u H mostu menja se srednja struja kroz namotaje, ali u trenutku kada je IGBT otvoren
napon na namotaju je jednak DC busu (ako nema kočenja motora u tom trenutku).

Napon DC busa bi trebao biti za 20% do veći od radnog napona motora.
