Buna ziua,Exista o metoda de "echivalare" a performantelor unui motor cu rotor bobinat cu unul cu rotor colivie?Aplicatie: motor 7.5kW pentru instalatie parc de distractiereostat in doua trepteCerinta: upgrade la motor actionat de convertizor.Problema principala consta in alegerea unui motor capabil sa dezvolte un cuplu suficient pentru a pune in miscare echipamentul mecanic.Va multumesc.

Motorul porneste in sarcina.Am facut inregistrare de curent si turatie pentru un ciclu de functionare.La punerea sub tensiune cu reostat complet introdus in circuitul rotoric am un varf de aprox 8.5A care coboara la 5.1A dupa ce turatia la axul motorului atinge prima viteza de 600 rpm (in aproximativ 80 secunde).Urmeaza scoaterea unei rezistente din circuitul rotoric si motorul mai are un soc de curent aproximativ de aceeasi valoare urmand a se stabiliza undeva la 6A si 1000 rpm.Ultima viteza foarte rar folosita, inseamna la cuplare un soc de 33A care se stabilizeaza la 10A cu o turatie de 1450 rpm (fara reostat).Multumesc.
