Abstract

L'invention concerne un moteur électrique et son procédé de fabrication. Le stator 10 constitué par les tôles 11 a une forme cylindrique avec au moins deux rainures 14 diamétralement opposées et dirigées axialement. Les rainures se terminent à une certaine distance de chaque extrémité du stator par un bord radial 15. Chaque flasque 16 comporte une partie enfilée sur le stator et emboutie dans les rainures 14 contre le bord 15. L'invention s'applique notamment à des petits moteurs électriques.The invention relates to an electric motor and its manufacturing method. The stator 10 formed by the sheets 11 has a cylindrical shape with at least two diametrically opposed grooves 14 and axially directed. The grooves end at a certain distance from each end of the stator by a radial edge 15. Each flange 16 has a part threaded onto the stator and stamped into the grooves 14 against the edge 15. The invention applies in particular to small electric motors.
