Title (EN) DUAL-ROTOR SYNCHRONOUS ELECTRICAL MACHINES
(FR) MACHINES ÉLECTRIQUES SYNCHRONES À DOUBLE ROTOR
Abstract:
(EN) A dual-rotor machine comprising a dual rotor support structure rotatably connected to a frame. A stationary stator is disposed between the rotors and is fixed to the frame. An inner rotor and outer rotor, each comprising a permanent magnet Halbach array, are coaxially disposed with the stator and are rotable about the stator. In this configuration, the inner rotor channels its magnetic flux to its outside, while the outer rotor channels its magnetic flux to its inside. The magnetic flux density at the stator for the dual-rotor machine can be as high as 2 Tesla or higher for high-grade neodymium-iron-boron permanent magnet material, and the stored magnetic energy for conversion to mechanical or electrical energy available to the stator may be at least 0.5 kJ/m. The rotor Halbach arrays may comprise monolithic permanent magnets with continuously variable magnetic field direction.
(FR) L'invention porte sur une machine à double rotor qui comprend une structure de support de double rotor reliée rotative à un châssis. Un stator fixe est disposé entre les rotors et est fixé au châssis. Un rotor interne et un rotor externe, comprenant chacun un réseau de Halbach d'aimants permanents, sont disposés coaxiaux avec le stator et peuvent tourner autour du stator. Dans cette configuration, le rotor interne canalise son flux magnétique vers l'extérieur, tandis que le rotor externe canalise son flux magnétique vers l'intérieur. La densité de flux magnétique au niveau du stator pour la machine à double rotor peut atteindre 2 teslas ou plus pour un matériau d'aimant permanent néodyme-fer-bore de haute qualité, et l'énergie magnétique stockée en vue d'une conversion en énergie mécanique ou électrique disponible au niveau du stator peut être supérieure ou égale à 0,5 kJ/m. Les réseaux de Halbach des rotors peuvent comprendre des aimants permanents monolithiques à direction de champ magnétique continûment variable.
