Title (EN) ROTARY TRANSFORMER
(FR) TRANSFORMATEUR ROTATIF
Abstract:
(EN) A rotary transformer is disclosed which comprises a primary core (15) having a primary coil (17) wound thereon, and a secondary core (16) having a secondary coil (19) wound thereon, wherein said cores (15) are mounted for relative rotation about an axis of rotation (14). The transformer (11) being characterised in that one of said cores (15) comprises a plurality of core segments (15a, 15b, 15c, 15d) arranged in spaced-apart relation relative to one another in a substantially circular array about said axis (14), the other core (17) having a substantially annular configuration. In a particular embodiment, said primary core (15) is fixed and hence remains static during operation, and comprises a plurality of spaced apart core segments arranged in a circular array around said axis.
(FR) L'invention porte sur un transformateur rotatif qui comprend un noyau primaire (15), sur lequel est enroulée une bobine primaire (17), et un noyau secondaire (16), sur lequel est enroulée une bobine secondaire (19), lesdits noyaux (15) étant montés pour une rotation relative autour d'un axe de rotation (14). Le transformateur (11) est caractérisé en ce que l'un desdits noyaux (15) comprend une pluralité de segments de noyau (15a, 15b, 15c, 15d) agencés dans une relation d'espacement mutuel l'un par rapport à l'autre en un groupement sensiblement circulaire autour dudit axe (14), l'autre noyau (17) présentant une configuration sensiblement annulaire. Dans un mode de réalisation particulier, ledit noyau primaire (15) est fixe et reste donc statique durant un fonctionnement, et comprend une pluralité de segments de noyau, espacés les uns des autres, agencés en un groupement circulaire autour dudit axe.
