Abstract

Viene descritto un nucleo del tipo tronco-conico, adatto per essere impiegato in una macchina elettrica rotante, comprendente un elemento statore ed un elemento rotore che ruota rispetto ad un asse di rotazione, detti elementi essendo separati da un traferro, detto nucleo essendo ottenuto a partire da un nastro ferromagneticol lavorato in modo da presentare una serie di cave e denti ed avvolto secondo un procedimento a spirale, così da realizzare un nucleo a forma tronco-conica.La caratteristica principale del nucleo descritto è che il detto nastro viene lavorato in modo tale che almeno una parte di ogni dente non sia complanare con la parte restante del nastro opposto al dente.
