Abstract

CIRCUITO ELECTRONICO PARA REGULACION DE VELOCIDAD EN MOTORES DE CORRIENTE ALTERNA. SE DISPONE UN GENERADOR DE FRECUENCIAS PARA CONTROL DE VELOCIDAD, CUYA FRECUENCIA ELEGIDA SE COMPARA CON LA DEL MOTOR, OBTENIDA CON UN TACOGENERADOR, SIRVIENDO LA DIFERENCIA DE AMBAS FRECUENCIAS COMO SEÑAL DE CONTROL DEL DISPOSITIVO GENERADOR DE SEÑAL DE MANDO DE PAR DE FUERZAS, CONTROLANDO ESTA LA FRECUENCIA DEL INVERSOR (10) Y LA INTENSIDAD DE ALIMENTACION. LA ALIMENTACION DEL MOTOR SE REALIZA DESDE UNA FUENTE DE CONTINUA REGULABLE, CON POSTERIOR CONVERSION EN ALTERNA POR MEDIO DEL INVERSOR (10).
