Abstract

CODIFICADOR PARA SENSOR DE POSIçãO E SENSOR DE POSIçãO. O objeto da invenção se refere a um codificador para sensor de posição que compreende pelo menos uma junção (J) entre um pólo, dito pequeno (P), e um pólo, dito grande (G), que apresenta uma largura angular superior à largura angular do pólo pequeno, o pólo pequeno (P) e o pólo grande (G) que correspondem a cada junção (J) apresentando polaridades de sinais opostos, caracterizado pelo fato de que, para cada junção (J), o pólo grande (G) de um sinal dado é composto: ò por um lado, por pelo menos um pólo pequeno estabilizante (ps) de mesmo sinal contíguo ao pólo pequeno (P) de sinal oposto e que apresenta uma largura angular sensivelmente idêntica ao dito pólo pequeno, ò e por outro lado, por pelo menos um pólo complementar (pc) de mesmo sinal que o pólo estabilizante (ps), o pólo complementar (pc) e/ou o pólo pequeno estabilizante (ps) apresentando um perfil de imantação gradual adaptado para estabilizar a passagem a zero Gauss da componente radial da indução magnética.
