Abstract
DISPOSITIVO ELECTRONICO PARA LA REGULACION DE LA VELOCIDAD MAXIMA DEL MOTOR EN LAS MAQUINAS DE COSER ELECTRICAS. CONSTA DE UN CIRCUITO DE ALIMENTACION CON UN PUENTE RECTIFICADOR DE ONDA COMPLETA, UN CIRCUITO INDICADOR DE LA FUNCION REALIZADA POR LA MAQUINA CON DIODOS TIPO L. E. D.; EL MOTOR LLEVA UN BORNE CONECTADO AL POLO POSITIVO POR MEDIO DE UNA BOBINA DE CLOQUE DE RADIO FRECUENCIAS (14) Y EL OTRO BORNE A UN TIRISTOR (16) CUYA REGULACION SE REALIZA POR UN CIRCUITO ASISTIDO CON EL PEDAL VACIADOR DE VELOCIDAD (17).
