Abstract

Un rotore a magneti permanenti per macchine elettriche, specialmente per l'impiego come rotore ad umido ad esempio in pompe per combustibile, presenta più segmenti (11) a magnetismo permanente, a forma di guscio, che si commettono reciprocamente in direzione periferica e sono sostenuti solidale alla rotazione su un cilindro portante (10) per mezzo di un dispositivo di fissaggio (12). Per l'ottenimento di modesti costi di fabbricazione mediante montaggio razionale, con sufficiente resistenza nei confronti di alti numeri di giri, ogni bordo superiore, opposto al cilindro portante (10), in corrispondenza dei lati frontali dei segmenti magnetici (11) è dotato di uno smusso (25, 26) che viene impegnato superiormente rispettivamente da un bordo (27, 28) ricavato in corrispondenza di cappe anulari (13, 14). Le cappe (13, 14) sono calzate sui lati frontali dei segmenti magnetici (11) e fissate sul cilindro portante (10) in modo da non poter scorrere assialmente e radialmente (figura 1).
