Abstract

CAPTOR MAGNéTICO DE POSIçãO TEM DETECçãO OTIMIZADA. A presente invenção se refere a um captor de posição caracterizado por o pólo irregular (Pi) compreender os meios (10) de correção do valor de seu campo magnético, de maneira a estabilizar o sinal diferencial, de modo que a parte do sinal diferencial passe por zero e situada entre as partes do sinal diferencial correspondente à passagem dos pólos adjacentes, compreender uma inclinação cujo valor, em valor absoluto, é sensivelmente idêntico aos valores das inclinações do sinal diferencial passadas por zero e correspondentes às passagens dos outros pólos.
