Abstract

Una carcasa magnéticA de sección transversal poligonal para una máquina dinamoeléctrica que comprende una pluralidad de dispositivos de campo unidos a la carcasa magnética, cada uno de los cuales comprende una bobina que rodea a un núcleo magnético, y un inducido soportado para rotación centradamente respecto a la carcasa magnética, caracterizándose dicha carcasa magnética de sección transversal poligonal porque está dispuesta de tal modo que las superficies dirigidas radialmente hacia dentro para montar los dispositivos de campo son superficies cilíndricas arqueadas cóncavas mecanizadas, las cuales se han mecanizado circularmente de modo que presenten superficies cilíndricas arqueadas concéntricas con el mismo radio de curvatura desde el mismo centro, que está en el eje central longitudinal de la máquina dinamoeléctrica.
