Abstract

"SENSOR DE POSIçãO PELA DETECçãO DE UM CAMPO MAGNéTICO TANGENCIAL". A invenção se refere a um sensor de posição do tipo que compreende um codificador formado por um anel magnético multipolar (1) provido sobre sua circunferência de pólos norte e de pólos sul alternados e montados para circular frente a uma célula de medida (2) pelo menos um dos ditos pólos de um sinal determinado é dito 'irregular' e compreende, em particular, meios para a correção do valor do campo magnético, de forma a estabilizar o sinal magnético emitido, pela passagem dos pólos vizinhos ao dito pólo irregular. De acordo com a invenção: 'a célula de medida (2) é sensível à componente tangencial do campo magnético emitido pelos pólos,' os meios para correção são realizados por uma zona de superfície (4) do pólo irregular (Pi) cercado por um pólo de ligação (5) com os pólos adjacentes, de mesmo sinal que os pólos adjacentes, os meios para correção (3) sendo realizados de forma que o sinal magnético tangencial, gerado entre a passagem de cada pólo adjacente ao dito pólo irregular, varie de maneira monótona.
