Abstract

L’invention présente une machine électrique comportant une culasse supportant N bobines toroïdales et un rotor central comportant un aimant permanent. La culasse est constituée d’une pluralité d’éléments statoriques en un matériau ferromagnétique doux supportant au moins une bobine. Les éléments statoriques présentent à leurs extrémités frontales des surfaces d’accouplement complémentaires assurant une continuité magnétique. Cette machine comporte en outre une enveloppe extérieure cylindrique en un matériau conducteur thermique, une pluralité de nervures longitudinales s’étendant radialement et positionnées entre ladite enveloppe extérieure cylindrique et lesdits éléments statoriques, afin d’assurer le positionnement mécanique de ladite culasse par rapport à ladite enveloppe extérieure et favoriser une conduction thermique des calories de ladite culasse vers ladite enveloppe extérieure.
