Abstract

MONITOR PARA MOTOR DE CAMPO MAGNETICO. CONSTA DE UN CONVERTIDOR ANALOGICO-DIGITAL (13) DISPUESTO PARA PROPORCIONAR REPRESENTACIONES DIGITALES DE VALORES INSTANTANEOS DE UN CAMPO MAGNETICO DE UN MOTOR A UN PROCESADOR DIGITAL (14); DE UNA FUENTE DE IMPULSOS DE RELOJ (20) PARA PROPORCIONAR IMPULSOS DE RELOJ AL PROCESADOR (14), ESTANDO DICHA FUENTE (20) SINCRONIZADA A UNA SEÑAL EXTERNA REPETITIVA; DE UN TEMPORIZADOR QUE CONTROLA LA FRECUENCIA DE LOS IMPULSOS DE RELOJ PROPORCIONADOS POR LA FUENTE (20), MEDIANTE LA APARICION DE UN IMPULSO DE TEMPORIZACION. DE APLICACION EN MOTORES ELECTRICOS.
