Motoare: NEMA34 20-30Kgf*cm cu curea, pentru o viteza maxima de pana in 20m/min, NEMA23 sau chiar 17, 4-10kgf*cm cu tija filetata, pentru viteze de deplasare considerabil mai mici. Scuze, dar asemenea greselile de ortografie taie orice chef de dialog :(

Si cu astea poti sa lucrezi la rezolutii cat de cat rezonabile ?Ma refer la motoarele DC. THX.

In mediul industrial se folosesc exclusiv servomotoarele (motor+encoder sau resolver),care au cel putin 3 avantaje fata de MPP,si anume: viteza precizie cuplu.Pentru aplicatii de mica putere (ex.plottere) se folosesc motoare de CC, iar pentru aplicatii de medie si mare putere se folosesc motoare 3 Phase.Acestea din urma sunt construite identic ca si motoarele asincrone,diferenta este ca nu se utilizeaza un rotor in scurtcircuit ci un rotor magnetic multipolar.Ca raspuns la intrebarea daca sunt cat de cat precise,este un DA mai mare,sunt foarte precise.Insa constructia unui CNC cu servomotore nu este o solutie la indemana multora.La nivel mediu se prefera utilizarea MPP.
