Abstract

1. Circuito magnético de chapas de entrehierro fijo, compuesto por una parte en E y una parte en I, y en el cual la longitud de las barras de extremidad d ela parte en E predetermina el espesor del entrehierro en frente de la barra central, caracterizado proque el lado de la parte en I que descansa sobre las barras de extremidad de la parte en E forma con los lados en el extremo de la parte en I un ángulo obtuso y proque las dos barras de extremidad de la parte en E poseen dos prolongaciones dispuestas una de otra a la distancia de la longitud de la parte en I para abrazar la parte en I casando con dicho ángulo obtuso. 2. Circuito magnético de chapas, de entrehierro fijo, según la reivindicación 1, caracterizado porque la parte en I comprende un debilitamiento de su sección, de preferencia un agujero, en frente de la barra central de la parte en E. 3. Circuito magnético de chapas, de entrehierro fijo, según una de las reivindicaciones 1 ó 2, caracterizado porque para el ajuste del entrehierro medio se deforman por depresiones puntuales dosificadas y limitadas en uno o más puntos una o más chapas de la parte en I para que se acerquen a la barra central de la parte en E. 4. Circuito magnético de chapas, de entrehierro fijo.
