Abstract

Le moteur selon l'invention comprend une tôle mince et souple 1 pourvue d'un orifice circulaire et formant un joint étanche 7 avec la carcasse 6 du moteur. Cette tôle est soudée à l'extrémité libre d'une gaine 3 formant écran de telle façon que la gaine et l'orifice de la tôle soient concentriques. Le stator 4 est placé avec ses enroulements 5 autour de la gaine. La carcasse 6 formant une seule pièce avec la boîte à bornes 8 est montée contre la partie en saillie 7 de la tôle et autour du stator. Le stator est rempli d'un mélange à mouler 9 que l'on laisse durcir et on monte enfin le rotor et les autres élements. Applications : moteurs pour pompes de circulation de chauffage central.The motor according to the invention comprises a thin and flexible sheet 1 provided with a circular orifice and forming a tight seal 7 with the frame 6 of the motor. This sheet is welded to the free end of a sheath 3 forming a screen so that the sheath and the orifice of the sheet are concentric. The stator 4 is placed with its windings 5 around the sheath. The frame 6 forming a single piece with the terminal box 8 is mounted against the projecting part 7 of the sheet and around the stator. The stator is filled with a molding mixture 9 which is left to harden and the rotor and the other elements are finally mounted. Applications: motors for central heating circulation pumps.
