Abstract

1. PROCEDIMIENTO PARA CONTROLAR EL NUMERO DE REVO- LUCIONES PARA UN MOTOR DE INDUCCION MONOFASICO O MULTIFASICO CON N(N=1,2,3...) ENROLLAMIENTOS DE FASE MEDIANTE MODIFICACION DE LA FRECUENCIA DE ES- TAS N TENSIONES FASICAS QUE OPERAN AL MOTOR Y QUE CADA CASO ESTAN DESPLAZADAS DE FASE POR UNA MAGNI- TUD DE 2(PI)/N CARACTERIZADO PORQUE LAS TENSIONES FASICA SE FORMAN POR CONMUTACION DE LOS POTENCIA- LES DERIVABLES DE n(n=2,3,4,...) FUENTES DE TEN- SION CONTINUA MONTADAS EN SERIE CON n DIFERENTES TENSIONES EJ: (J=1,2,..,n) A LAS BORNAS DE SALIDA EN UNA SECUENCIA DE LAPSOS DE TIEMPO PREDETERMINA- BLES LA CUAL SE REPITE CONTINUAMENTE CON UNA DURA- CION DE PERIODO T Y EN UNA SECUENCIA PREESTABLECI- DA, EN QUE A CADA POTENCIAL CONMUTADO ESTA ADJUDI- CADO UNO DE LOS LAPSOS DE TIEMPO Y PORQUE LA FRE- CUENCIA f=1/T DE LAS TENSIONES FASICAS SE MODIFICA MEDIANTE AUMENTO O DISMINUCION DE LA DURACION DE UNO O VARIOS DE LOS LAPSOS DE TIEMPO DETERMINADOS.1. PROCEDURE TO CONTROL THE NUMBER OF REVOLUTIONS FOR A SINGLE-PHASE OR MULTI-PHASE INDUCTION MOTOR WITH N (N = 1,2,3 ...) PHASE WINDINGS THROUGH MODIFICATION OF THE FREQUENCY OF THESE N PHASE VOLTAGES OPERATING TO THE MOTOR AND THAT EACH CASE ARE DISPLACED IN PHASE BY A MAGNITUDE OF 2 (PI) / N CHARACTERIZED BECAUSE THE PHASE VOLTAGES ARE FORMED BY SWITCHING THE POTENTIALS DERIVABLE FROM n (n = 2,3,4, .. .) SERIES-MOUNTED CONTINUOUS VOLTAGE SOURCES WITH n DIFFERENT VOLTAGES EX: (J = 1,2, .., n) TO THE OUTPUT TERMINALS IN A SEQUENCE OF DEFAULT TIME LAPSES WHICH IS CONTINUOUSLY REPEATED WITH A DURATION OF PERIOD T AND IN A PRE-ESTABLISHED SEQUENCE, IN WHICH ONE OF THE TIME LAPSES IS AWARDED TO EACH TIME LAPSE AND BECAUSE THE FREQUENCY f = 1 / T OF PHASE VOLTAGES IS MODIFIED BY INCREASE OR DECREASE IN THE DURATION OF ONE OR SEVERAL OF THE DETERMINED TIME LAPSES.
