Abstract

Patente de Invenção: <B>"SENSOR DE ROTAçõES"<D>. Em um sensor de ângulo de rotação ou número de rotações, com um transmissor de impulsos disposto sobre um elemento de rotação (10), que apresenta um ímã anular (11) produzido como peça injetada, e uma bucha metálica (12), que aloja com fecho devido à forma o ímã anular (11), o ímã anular (11) está alojado com uma primeira seção anular (111) sobre a bucha (12) e com uma segunda seção anular (112) está inserido com ajuste prensado sobre o elemento de rotação (10). A bucha (12) está fixada sobre o elemento de rotação (10), na região de uma seção de bucha (121), que se salienta frontalmente do ímã anular (11), e o fecho devido à forma entre a bucha (12)e a primeira seção anular (111) está produzida por elementos moldados sobre o perímetro externo das buchas (12), sobre os quais o ímã anular (11) está injetado.
