Title (EN) SEGMENT MAGNET AND PERMANENT MAGNET MOTOR COMPRISING SEGMENT MAGNETS
(FR) AIMANT SEGMENTÉ ET MOTEUR À AIMANT PERMANENT MUNI D’UN AIMANT SEGMENTÉ
(DE) SEGMENTMAGNET UND PERMANENTMAGNETMOTOR MIT SEGMENTMAGNETEN
Abstract:
(EN) The invention relates to an optimized segment magnet for a permanent magnet motor. By establishing a magnetization profile within the segment magnet in accordance with a continuous cyclic function, optimized operating characteristics for the electric motor can be achieved with a reduced use of material. The cyclic formation of the magnetization direction in the segment magnet can also be combined with shaping in accordance with a further cyclic function, in order to intensify this effect further.
(FR) L'invention concerne un aimant segmenté optimisé destiné à un moteur à aimant permanent. L’établissement d’une courbe de magnétisation à l’intérieur de l’aimant segmenté selon une fonction cyclique continue permet d’obtenir des caractéristiques de fonctionnement optimisées pour une moindre utilisation de matière. La formation cyclique de la direction de magnétisation dans l’aimant segmenté peut en outre être combinée à une mise en forme selon une autre fonction cyclique pour renforcer encore cet effet.
(DE) Die die vorliegende Erfindung schafft einen optimierten Segmentmagneten für einen Permanentmagnetmotor. Durch das Einstellen eines Magnetisierungsverlaufs innerhalb des Segmentmagnets gemäß einer stetigen zyklischen Funktion können bei verringertem Materialeinsatz optimierte Betriebseigenschaften für den Elektromotor erzielt werden. Die zyklische Ausbildung der Magnetisierungsrichtung in dem Segmentmagnet kann darüber hinaus mit einer Formgebung gemäß einer weiteren zyklischen Funktion kombiniert werden, um diesen Effekt weiter zu verstärken.
