Abstract

Przedmiotem zgłoszenia przedstawionym na rysunku jest wirnik silnika synchronicznego, zawierający rdzeń wykonany z kołowych kształtek wykonanych z blachy, w których wykrojone są żłobki mieszczące magnesy trwałe rozmieszczone według podziałki biegunowej. Każda podziałka biegunowa zawiera dwa podłużne żłobki rozchodzące się rozbieżnie w kierunku zewnętrznej krawędzi kształtki wirnika, symetrycznie względem osi symetrii podziałki biegunowej. Na wewnętrznym i zewnętrznym końcu każdego żłobka umiejscowione są zamknięte i puste wpust wewnętrzny i wpust zewnętrzny. Między każdym żłobkiem a jego wpustem wewnętrznym znajduje się wewnętrzne podcięcie blokujące oraz między każdym żłobkiem a jego wpustem zewnętrznym znajduje się zewnętrzne podcięcie blokujące. Na osi symetrii każdej podziałki biegunowej między wpustami wewnętrznymi sąsiednich żłobków znajduje się warstwa materiału blachy stanowiąca przesmyk wewnętrzny. Pomiędzy sąsiednimi podziałkami biegunowymi, między wpustami zewnętrznymi sąsiednich żłobków znajduje się warstwa materiału blachy, stanowiąca przesmyk zewnętrzny. Między każdym z wpustów zewnętrznych a zewnętrzną krawędzią kształtki wirnika znajduje się warstwa materiału blachy, stanowiąca przesmyk krawędziowy.The subject of the application presented in the drawing is a synchronous motor rotor, comprising a core made of circular shapes made of sheet metal, in which slots are cut out to contain permanent magnets arranged according to a pole pitch. Each pole pitch comprises two elongated slots extending divergently towards the outer edge of the rotor shape, symmetrically with respect to the axis of symmetry of the pole pitch. At the inner and outer ends of each slot, a closed and empty inner key and an outer key are located. Between each slot and its inner key, there is an inner locking undercut, and between each slot and its outer key, there is an outer locking undercut. On the axis of symmetry of each pole pitch, between the inner keys of adjacent slots, there is a layer of sheet metal material constituting an inner isthmus. Between adjacent pole pitches, between the outer keys of adjacent slots, there is a layer of sheet metal material constituting an outer isthmus. Between each of the external inlets and the outer edge of the rotor profile there is a layer of sheet material constituting an edge isthmus.
