CA 2426922

The invention relates to a rotor for an electric machine, especially a synchronous machine with a transverse flux, especially a synchronous generator, especially a TFM rotor. The invention is characterised by the following features: a support element; a pole structure which is located on a first end face in the area of the outer periphery of the support element and which comprises two rows of magnet arrangements, these magnet arrangements being magnetised alternately in the peripheral direction, and collectors or soft iron elements being located between the magnet arrangements and being separated by an intermediate layer of electrically and magnetically non- conductive material; on the second end face pointing away from the first end face, the support element has at least one partial area which forms a flange surface for applying to a connecting element and in which means are provided for guiding means for creating a rotationally fixed connection or partial elements of means for creating a rotationally fixed connection are located.

L'invention concerne un rotor pour une machine électrique, notamment une machine synchrone à flux transversal, en particulier un générateur synchrone et plus précisément un rotor à flux transversal. L'invention est caractérisée en ce qu'elle comprend les éléments suivants : un élément support ; une structure polaire disposée sur la première face frontale, dans la zone circonférentielle extérieure de l'élément support, et constituée de deux rangées d'ensembles d'aimants, magnétisés alternativement dans le sens circonférentiel, avec, logés entre elles, des éléments collecteurs ou en fer doux, séparés par une couche intermédiaire en matériau électriquement et magnétiquement non conducteur ; sur la deuxième face frontale, opposée à la première face frontale, au moins une zone partielle constituant une surface de bridage destinée à s'appliquer contre un élément de raccordement. Dans cette zone partielle sont disposés des éléments pour guider des moyens destinés à créer une liaison résistante à la torsion, ou des éléments partiels de moyens destinés à créer une liaison résistante à la torsion.
