Abstract
(EN)
The present patent application pertains to the field of articles for the generation, conversion or distribution of electrical energy, and more specifically to the branch of dynamo-electric machines. The invention proposes an electromagnetic motor with magneto-mechanical actuation and switching. Hitherto known low-cost motors are very inefficient, while motors with permanent magnets and more sophisticated control electronics, although more efficient, are expensive. In addition to this, it is difficult to use simpler mechanical switches due to the presence of electrical arcing during the change of polarity in the electromagnetic coils. Unlike these models, the subject matter of the present application relates to a motor with two-wire or multi-wire electromagnetic coils in which the change of polarity is effected by a magneto-mechanical switch (9) controlled by a switching rotor (5) fastened to the shaft (1) of the rotor of the motor itself.

La présente demande de brevet relève du domaine des articules pour la production, la conversion ou la distribution d’énergie électrique, notamment le secteur des machines dynamo-électriques, et consiste en un moteur électromagnétique avec actionnement et commutation magnéto-mécanique. Les moteurs de faible coût connus jusqu’ici sont très inefficaces alors que les moteurs à aimants permanents et électronique de commande plus sophistiquée, qui sont efficaces, présente un coût élevé. Par ailleurs, il devient difficile d’utiliser des commutateurs mécaniques plus simples du fait de la présence de l’arc électrique pendant le changement de polarité dans les bobines électromagnétiques. À la différence de ces modèles, l'objet de la présente demande consiste en un moteur à bobines électromagnétiques bifilaires ou multifilaires, dont le changement de polarité dans celles-ci est réalisé par un commutateur magnéto-mécanique (9), commandé par un rotor de commutation (5) fixé à l’axe (1) du rotor du moteur lui-même.
