Title (EN) PERMANENT MAGNET RELUCTANCE MACHINES
(FR) MACHINES À RÉLUCTANCE À AIMANT PERMANENT
Abstract: front page image
(EN)An electrical machine comprising a rotor (11) with magnetic saliency but without windings, a stator (101) having stator teeth, the stator carrying armature windings (106, 111) wound with a pitch corresponding to a plurality of stator teeth and arranged around the stator to make one or more electrical phases, the stator also including a field magnet means, interspersed between every two stator teeth, wherein the field magnet means comprises at least one field winding (191, 192) and at least one permanent magnet (104, 105), and a field current control means such that variation of the direct current in the field windings changes the number of magnetic poles in the machine. The armature coils of the machine can be configured into one or more armature windings and circuits are described to excite the armature coils in the most efficient manner depending on the load or application requirements of the machine.
(FR)L'invention concerne une machine électrique comprenant un rotor (11) à relief magnétique mais sans enroulements ; un stator (101) comprenant des dents de stator, le stator comportant des enroulements d'armature (106, 111) enroulés avec un pas correspondant à une pluralité de dents de stator et disposés autour du stator pour produire une ou plusieurs phases électriques, le stator comprenant également un moyen d'aimant à champ, intercalé toutes les deux dents de stator, le moyen d'aimant à champ comprenant au moins un enroulement de champ (191, 192) et au moins un aimant permanent (104, 105), et un moyen de régulation du courant de champ de telle sorte que la variation du courant continu dans les enroulements de champ modifie le nombre de pôles magnétiques dans la machine. Les bobines d'armature de la machine peuvent être configurées en un ou plusieurs enroulements d'armature et l'invention concerne également des circuits pour exciter les bobines d'armature de la façon la plus efficace possible, selon les besoins de charge ou d'application de la machine.
