Abstract

COMPENSACION DE LA TENSION DE ESCOBILLAS EN UN MOTOR-GENERADOR.UN MOTOR DE CORRIENTE CONTINUA (18) QUE ACCIONA UN ASCENSOR RECIBE SU TENSION DE ENTRADA A PARTIR DEL INTRODUCIDO GIRATORIO (12) DE UN GRUPO MOTOR-GENERADOR UTILIZANDO UN MOTOR (10) DE ACCIONAMIENTO DE INDUCIDO (12) GIRA EN LA PRESENCIA DE UN CAMPO DE CORRIENTE CONTINUA PRODUCIDO POR UNA PRIMERA BOBINA (20) QUE ESTA ENROLLADA EN UN NUCLEO MAGNETIZABLE. LA CORRIENTE QUE ATRAVIESA ESTA BOBINA (20) ESTA CONTROLADA POR UN CONTROL DE VOLOCIDAD Y DIRECCION DE MOTOR (22) PARA REGULAR LA TENSION APLICADA AL MOTOR DE ACCIONAMIENTO DEL ASCENSOR. UNA BOBINA ADICIONAL (30) ESTA DISPUESTA PARA INDUCIR UNA TENSION ADICIONAL CUYA MAGNITUD ES IGUAL A LA CAIDA DE TENSION A TRAVES DE LAS ESCOBILLAS (14) DEL INDUCIDO PERO DE POLARIDAD OPUESTA. ESTA TENSION SE PRODUCE DETECTANDO LA CORRIENTE DEL MOTOR Y APLICANDOLA A UNA SEGUNDA BOBINA (30), LA CUAL PRODUCE UN CAMPO AL CUAL ESTA SOMETIDO EL INDUCIDO MIENTRAS GIRA. CUANDO LA CORRIENTE QUE ATRAVIESALA PRIMERA BOBINA (20) TOMA EL VALOR CERO, SE INVIERTE LA DIRECCION DE LA CORRIENTE EN LA SEGUNDA BOBINA. ESTO SE HACE PARA MINIMIZAR LA TENSION DE SALIDA DE INDUCIDO PRODUCIDA POR EL MAGNETISMO RESIDUAL DE LA PRIMERA BOBINA.
