Abstract

Accionador magnético rotativo, del tipo que incluye un estátor (1) de P pares de polos, que comprende un circuito magnético estatórico de un material ferromagnético dulce, y que presenta pares de expansiones polares (7, 8) y al menos una bobina eléctrica (3) de excitación, y un rotor (2) que comprende un circuito magnético (9) rotórico, de material ferromagnético dulce, que está situado frente a las citadas expansiones polares del circuito magnético estatórico, y que es solidario con un árbol axial, incluyendo el circuito magnético rotórico un imán anular (10) multipolar de P pares de polos, en el que dicho circuito magnético estatórico presenta un núcleo (5) central sobre el que se ha bobinado la bobina (3) de excitación, que se caracteriza porque el citado núcleo y la bobina de excitación presentan una sección transversal no circular, en forma de polígono, que ocupa sensiblemente toda la superficie dejada por el resto del circuito magnético estatórico.
