Abstract

Rotorul pentru masini electrice, conform inventiei, fiind de tipul cu magneti permanenti orientati tangential si montati între niste piese polare, are pe suprafata laterala a pieselor polare niste canale longitudinale, în care sunt introduse niste stifturi mai lungi ca piesele polare, capetele stifturilor fiind conectate unele cu altele si cu axul masinii prin intermeediul unor elemente nemagnetice.According to the invention, according to the invention, the rotor for electric machines is tangential-oriented and mounted between some polar pieces and has longitudinal channels on the lateral surface of the pole pieces, in which some longer studs are inserted as polar parts, the ends of the pins being connected with each other and with the axle of the car through the intermediary of non-magnetic elements.
