Abstract

Patente de Invenção para "SENSOR DE POSIçãO DE ALTARESOLUçãO". A invenção se refere a um sensor comportandopelo menos um codificador magnético rotativo do tipo quecomporta pelo menos uma pista magnética circular, formada poruma série de elementos geradores de um campo magnéticovariável, repartido-se para formar pares de elementos com umperíodo mecânico igual a 360<198>/P, a pista magnética sendodestinada a desfiar na frente de pelo menos uma célula dedetecção liberando um sinal elétrico periódico De acordo com ainvenção, o codificador comporta seja uma série de <UM>n<MV>pistas magnéticas circulares, destinadas a desfiar, cada uma, nafrente de uma célula de detecção, montadas de maneira que osditos elementos (5) das pistas se encontrem deslocadosangularmente entre si; seja uma pista magnética circular destinadaa desfiar na frente de <UM>n<MV> células de detecção,deslocadas angularmente entre elas, o deslocamento angularrelativo entre os elementos geradores e as células sendo adaptadopara obter <UM>n<MV> sinais elétricos, defasados eletricamenteentre si de um valor igual a 1/2 <UM>n<MV> vezes o valor doperíodo, permitindo, desta forma, aumentar a resolução em<UM>n<MV> vezes.
