Abstract

PERCUTORES DE ATRACCION Y BLOQUEO MAGNETICO CON UMBRAL DE DESBLOQUEO CONSTANTE. CONSTA DE UN BOBINADO DE EXCITACION Y UN NUCLEO BUZO MAGNETICO QUE TIENE UNA PRIMERA PORCION QUE PENETRA AXIALMENTE EN EL BOBINADO, UNA SEGUNDA PORCION Y UNA TERCERA PORCION INTERMEDIA ENTRE LOS ANTERIORES; UNA CULATA MAGNETICA DE LA QUE UN ELEMENTO PENETRA PARALELAMENTE EN EL BOBINADO PARA PRESENTAR UNA PRIMERA SUPERFICIE POLAR QUE COOPERA POR UN ENTREHIERRO AXIAL CON LA PRIMERA PORCION EXTENDIENDOSE OTROS ELEMENTOS DE ESTA CULATA A CONTINUACION ALREDEDOR DEL BOBINADO PARA FORMAR UNA SEGUNDA SUPERFICIE POLAR, QUE COOPERA POR UN SEGUNDO ENTREHIERRO RADIAL CON LA SEGUNDA PORCION DEL NUCLEO Y UNA TERCERA SUPERFICIE POLAR, QUE COOPERA CON LA TERCERA PORCION DEL NUCLEO POR UN TERCER ENTREHIERRO AXIAL DE VALOR REDUCIDO.
