Reglarea turatiei la motor monofazat.


Recommended Posts

Buna ziua,Doresc sa realizez un circuit ca cel din imaginea din atasament, numai ca motorul pe care il am este de 4 A 220V. Ce modificari trebuie sa fac la acest circuit pentru a suporta un astfel de motor? Banuiesc ca trebuie sa schimb triac-ul..., dar mai trebuie schimbat si altceva? Ce triac imi recomandati?Multumesc mult.

Inainte m-am gandit si la asta, dar nu cred ca e o varianta buna.Intre timp m-am razgandit si o sa folosesc motor de curent continuu cum e cel de la bormasina. Cum pot controla turatia unui astfel de motor? Ultima data am facut cu PWM - o schema cu LM555. Vreau chiar varianta folosita de bormasina.Are cineva schema a ceea ce se gaseste in acel buton de la bormasina pentru reglarea turatiei?Va multumesc pentru ajutor!
