Abstract

"MéTODO DE DETERMINAçãO DA VELOCIDADE DE ROTAçãO DE UM MOTOR, E, PRODUTO DE SOFTWARE DE COMPUTADOR PARA DETERMINAR A VELOCIDADE DE ROTAçãO DE UM MOTOR". A presente invenção se refere a um método de determinação de velocidade de rotação de um motor (1). O método envolve a coleta de amostras (x[n]) com um sensor de medição (2) em uma freq³ência de amostragem (f~ S~) ajustada com base em vibração mecânica do motor (1) para a extensão de um período de medição (T) e armazenamento das amostras (x[n]) na memória de um portador de dados (4) como dados de medição de um formato fixo. A velocidade de rotação do motor (1) é determinada dos dados de medição pela determinação da extensão do ciclo de um sinal de vibração periódico no domínio de tempo por meio de uma estimativa de probabilidade máxima calculada pela maximização de uma função de probabilidade máxima (J) ajustada aos dados de medição, a velocidade de rotação sendo obtida do ponto de freq³ência (13f) onde a função de probabilidade máxima obtém seu valor máximo (13 max).
