Abstract
Dispositivo para la propulsión de una máquina de coser con número de revoluciones regulador, con un motor-embrague eléctrico, que tiene un órgano de embrague puesto en comunicación de propulsión con el árbol de la máquina de coser, el cual puede ser embragado con un árbol de propulsión principal constantemente propulsado del motor- embrague y/o con un soporte de freno a través de un embrague de fricción accionado electromagnéticamente, así como con un regulador que alimenta con corriente el embrague de fricción y/o el freno de fricción, el cual regulador, con el fin de propulsar el árbol de la máquina de coser con un número de revoluciones de trabajo previamente establecido puede ser alimentado con una desviación de regulación, que es obtenida mediante comparación de una amplitud de tensión que representa el número de revoluciones real, suministrada constantemente por un indicador del número de revoluciones real.
