Abstract

SENSOR DE POSIÇÃO ANGULAR. A invenção refere-se a um sensor de posição angular (24) e um método que se vale de um conjunto estacionário circular de sensores de hall (18) e um conjunto giratório circular de magnetos (16) dispositivos em torno de um eixo geométrico comum (22). Utiliza-se uma leitura periódica e simultânea de todas as saídas dos sensores de hall para determinar a velocidade angular.
