Patent
CA 2369956
The invention relates to a rotor device (1) in which a rotor (3, 30, 32, 36, 42) interacts with a fluid. The invention is characterized in that: a) the rotor device (1) comprises a support tube (2); b) a rotor (3, 30, 32, 36, 42) is mounted in said support tube (2) in a rotating manner; c) the rotor (3, 30, 32, 36, 42) is configured such that it can interact with a fluid flowing through the support tube (2); d) on both end faces the rotor (3, 30, 32, 36, 42) has axially magnetized permanent-magnet rotor magnets (7, 8; 46, 47); e) permanent magnet stator magnets (18, 19; 52, 53) which are connected to the support tube (2) are mounted axially opposite the face ends of the rotor (3, 30, 32, 36, 42); f) each stator magnet (18, 19; 52, 53) is axially magnetized in such a way that adjacent stator and rotor magnets (18, 19; 7, 8; 46, 47; 52, 53) attract each other; and g) the rotor device (1) comprises a magnetic axially stabilizing device (22, 23, 27; 58, 59, 66) for the rotor (3, 30, 32, 36, 42).
La présente invention concerne un dispositif à rotor (1) destiné à l'interaction d'un rotor (3, 30, 32, 36, 42) avec un fluide. L'invention se caractérise en ce que a) ledit dispositif à rotor (1) comprend un tube support (2), b) un rotor (3, 30, 32, 36, 42) est disposé dans le tube support (2) de façon à pouvoir tourner, c) le rotor (3, 30, 32, 36, 42) est formé de façon à interagir avec le fluide s'écoulant dans le tube support (2), d) le rotor (3, 30, 32, 36, 42) présente, sur les deux faces, des aimants de rotor (7, 8; 46, 47) permanents à magnétisation axiale, e) des aimants de stator (18, 19; 52, 53) permanents, reliés au tube support (2), se trouvent axialement opposés au faces du rotor (3, 30, 32, 36, 42), f) chaque aimant de stator (18, 19; 52, 53) présente une telle magnétisation axiale que les aimants de stator et de rotor (18, 19; 7, 8; 46, 47; 52, 53) voisins s'attirent mutuellement, g) le dispositif à rotor (1) comporte un dispositif de stabilisation axiale (22, 23, 27; 58, 59, 66) magnétique destiné au rotor (3, 30, 32, 36, 42).
