Abstract

SE DISEÑA UN DISPOSITIVO DE CONTROL PARA DIRIGIR EL TAMBOR DE UNA MAQUINA DE LAVADO O DE SECADO PARA LAVANDERIA PARA VARIAR LA TASA DE GIRO DEL MOTOR (2) DE LA MAQUINA EN CASO DE QUE LOS BOBINADOS ELECTRICOS (4,9) ESTEN EXCESIVAMENTE CALIENTES. EL DISPOSITIVO CONSTA DE UN COMPARADOR ELECTRONICO (57) ADAPTADO PARA COMPARAR LOS VOLTAJES GENERADOS MEDIANTE UN SENSOR DE TEMPERATURA (3) COLOCADO CERCA DE LOS BOBINADOS (4,9) PARA DETECTAR SU TEMPERATURA DE CALENTAMIENTO, CON UN VOLTAJE DE REFERENCIA PREDETERMINADO DE TAL MODO QUE, DE ACUERDO CON ESTA COMPARACION, CONTROLA EL FUNCIONAMIENTO DEL MOTOR (2) A DIFERENTES TASAS POR MEDIO DE CIRCUITOS AND LOGICOS (63,64) CONECTADOS CON CONMUTADORES LOGICOS RESPECTIVOS (65,66) O POR MEDIO DE UN CIRCUITO AND LOGICO (73) ADAPTADO PARA DIRIGIR EL MOTOR (2) A UNA TASA INFERIOR QUE LE PERMITA ENFRIARSE GRADUALMENTE SI SUS BOBINADOS ESTAN SOBRECALENTADOS. DE ESTE MODO, DADO QUE EL MOTOR (2) NO ESTA DESCONECTADO PUESTO QUE EL ENLACE TERMICO (7) CONECTADO CONLOS BOBINADOS (4) DE ESTE NO INTERVIENE, UNO OBTIENE PROGRAMAS DE LAVADO Y SECADO EFICACES SIN NINGUNA NECESIDAD DE SOBREDIMENSIONAR EL MOTOR.
