Abstract

Una máquina eléctrica con un imán permanente (8) que incluye una superficie inferior (10) que puede disponerse en la circunferencia externa (6) del rotor (4), y una superficie externa (14,16,18) que está dirigida hacia el entrehierro (δ) de la máquina eléctrica, comprendiendo la superficie externa (14,16,18) del imán permanente (8) partes de borde (16,18) y una parte central (14), mediante lo cual el imán permanente tiene un grosor uniforme en la parte central (14), y con respecto a la parte de borde (16,18), el grosor del imán permanente disminuye uniformemente hacia el borde del imán permanente, caracterizada porque la diferencia en el grosor del imán permanente en la parte central y en el borde es igual al entrehierro (δ) de la máquina eléctrica, y porque la anchura de la parte central es igual a o mayor que la anchura combinada de las partes de borde.
