Title
(EN) AN ELECTRIC MACHINE UNIT
(FR) UNITÉ DE MACHINE ÉLECTRIQUE
Abstract
(EN) The present subject matter provides an electric machine unit (152) and a corresponding method for a motorized device (100). The electric machine unit (152) comprises a rotor assembly and a stator assembly. The stator assembly comprises a plurality of stator members, which are configured to work in conjunction with a corresponding plurality of rotor members of the rotor assembly. A mode selector (450) is configured to enable operation of one or more of the plurality of stator members to rotate a rotor shaft depending on or more parameters of the motorized device (100). The present subject matter provides a low-cost system, which is configured to optimally use power from the power source.
(FR) La présente invention porte sur une unité de machine électrique (152) et sur un procédé correspondant pour un dispositif motorisé (100). L'unité de machine électrique (152) comprend un ensemble rotor et un ensemble stator. L'ensemble stator comprend une pluralité d'éléments de stator, qui sont configurés pour fonctionner conjointement avec une pluralité correspondante d'éléments de rotor de l'ensemble rotor. Un sélecteur de mode (450) est configuré pour permettre le fonctionnement d'un ou de plusieurs éléments de stator parmi la pluralité d'éléments de stator pour faire tourner un arbre de rotor en fonction d'un ou de plusieurs paramètres du dispositif motorisé (100). La présente invention concerne un système à faible coût, qui est configuré pour utiliser de manière optimale de l'énergie provenant de la source d'alimentation.
