Title (EN) FERRITE THREE-PHASE PERMANENT MAGNET MOTOR
(FR) MOTEUR À AIMANTS PERMANENTS TRIPHASÉ EN FERRITE
(ZH) 铁氧体三相永磁电机
Abstract: front page image
(EN)A ferrite three-phase permanent magnet motor is provided. The slot number Z of stator is equal to 9. Slots used for embedding winding are formed in front, at the back, on the left and right of each tooth. Each phase has three concentrated windings in series enwinding three teeth separately. The arrangement of the 9 teeth enwinding three-phase windings A, B, C is A-B-C-A-B-C-A-B-C. The permanent magnet of rotor iron core is made by hard magnetic ferrite, and the number of magnetic poles 2P is equal to 6. The motor has advantages of small winding end, small positioning torque, less copper loss and iron loss et al.
(FR)L'invention concerne un moteur à aimants permanents triphasé en ferrite dans lequel le nombre de fentes Z du stator est de 9. Les fentes utilisées pour recevoir les enroulements sont formées à l'avant, à l'arrière, à gauche et à droite de chaque dent. Chaque phase comprend trois enroulements concentrés en série qui entourent trois dents séparément. La disposition des 9 dents enroulant les enroulements triphasés A, B, C est A-B-C-A-B-C-A-B-C. L'aimant permanent du noyau en fer du rotor est fait de ferrite magnétique dure, et le nombre de pôles magnétiques 2P est de 6. Le moteur a pour avantages une extrémité d'enroulement réduite, un faible couple de positionnement, une moindre concentration en cuivre et en fer, etc.
