Abstract

Patente de Invenção: <B>"PROCESSO PARA O RECONHECIMENTO DE PASSO EM MOTORES DE PASSO, SEM O USO DE SENSORES"<D>. é descrito um processo para o reconhecimento de passo de motores de passo por meio da an;alise da passagem de correte através do motor, sem o uso de sensores. Para superar os problemas causados pelo uso de uma resistência de derivação, os erros e balanço de medição de corrente resultantes, e para assegurar uma operação tão sem distúrbios e confiável quanto possível em todos os estados de operação de motores de passo unipolares e bipolares, o processo descrito tem as seguintes etapas de processos: uma corrente definida (T2) é aplicada em um enrolamento de motor (B) após uma reversão (T1) da direção de fluxo da corrente em uma primeiro enrolamento de motor (A); uma conexão de enrolamento de motor (B) é ligada com um elevado valor óhmico (T3); o sinal de resposta (S) na conexão de enrolamento de motor (B) ligada com um elevado valor óhmico é sentido; o comprimento (T3 - T4) do sinal de resposta é avaliado. Alternativamente, é provocado disparo por meio de um sinal de disparo externo, independentemente da reversão da direção de fluxo de corrente.
