Abstract

Moteur synchrone à démarrage automatique. Le moteur synchrone de la présente invention comporte un premier stator formé d'une tôle de stator supérieure 1 et d'une tôle de stator inférieure 2, pénétrant dans une bobine de stator 3. Chaque tôle de stator comporte des pièces polaires 5, 6 respectivement 7, 8 de polarité alternée, et correspondant à la polarisation de l'induit du moteur. Les pièces polaires de ce stator ne sont réparties que sur une zone de 180 degrés sur le pourtour de l'induit. Le deuxième stator est formé des tôles de stator 9 et 10, comportant des pièces polaires 16 à 19, décalées d'un demi-intervalle par rapport aux pièces polaires 5 à 8. La bobine 11 est reliée au réseau par un condensateur, de manière à faire apparaître un champ tournant. Application à un moteur synchrone à démarrage automatique de fabrication simplifiée et de très faible encombrement.Synchronous motor with automatic start. The synchronous motor of the present invention comprises a first stator formed of an upper stator sheet 1 and a lower stator sheet 2, entering a stator coil 3. Each stator sheet has pole pieces 5, 6 respectively. 7, 8 of alternating polarity, and corresponding to the polarization of the motor armature. The pole pieces of this stator are only distributed over an area of 180 degrees around the perimeter of the armature. The second stator is formed of the stator sheets 9 and 10, comprising pole pieces 16 to 19, offset by half an interval with respect to the pole pieces 5 to 8. The coil 11 is connected to the network by a capacitor, so to reveal a rotating field. Application to a synchronous motor with automatic start of simplified manufacture and very small footprint.
