Transcript of Motorul de curent continuu

Hrinca Bogdan-Gabriel Motorul de curent continuu Bibliografie Motorul de curent continuu prezinta o deosebita importanta inactionarile de reglaj de viteza avand o tot mai larga dezvoltare atatca fabricatie cat si ca utilizare.Aceste motoare sunt din ce in ce mai utilizate in tractiuneaelectrica, actionarea masinilor unelte in metalurgie, instalatii detransport si ridicat, etc. Statorul :

Rotorul : Motorul de curent continuu este alcatuit din 2 elemente :
In stator se afla infasurarea de excitatie care va produce un camp magnetic constant produs de niste electromagneti alimentati in curent continuu sau de niste magneti permanenti. Principiul de funcţionare
Infasurarea rotorica este alimentata la o sursa de curent continuu, prin urmare prin spirele rotorice va debita un curent electric. Asupra laturii spirei aflate sub polul nord va actiona o forta elctromagnetica iar asupra laturii spirei de sub polul sud va actiona o forta egala dar de sens contrar.Ca urmare asupra spirei va actionaun cuplu electromagnetic M care va rotis pira. Principiul de funcţionare
