Abstract

Nel caso di una macchina elettrica con un rotore rotante ed uno statore portante l'avvolgimento, per far sì che essa con semplici mezzi, in caso di modeste perdite elettromagnetiche sia ciò nonostante in grado di sostenere elevate sollecitazioni meccaniche, il rotore (2) e, oppure lo statore (1) è eseguito come pezzo ottenuto mediante pressatura di polvere metallica, laddove al materiale composito in polvere, che è costituito essenzialmente di particelle metalliche a basso campo coercitivo, dotate in tutte le direzioni di uno strato sottile, elettroisolante, e altamente permeabili, e inoltre di leganti, sono aggiunti lo 0,1-8% in peso di fibre di vetro, fibre di carbonio, fibre di ceramica o fibre di materiale artificiale (figura 1).
