Abstract

Electricité. Moteur électromagnétique pas à pas comprenant un stator réalisé en matériau ferro-magnétique doux présentant deux parties coplanaires imbriquées l'une dans l'autre et séparées par un entrefer sinueux présentant 2n segments radiaux angulairement équidistants, et un rotor constitué par un disque plat muni de n dents aimantées axialement dans le même sens ou de 2n dents aimantées axialement dans le sens alterné, situé en regard des segments radiaux du stator, caractérisé en ce qu'il comprend une pièce annulaire fixe entourant le rotor et qui présente une denture intérieure située sensiblement dans le plan du rotor de manière à présenter, vis-à-vis de celui-ci, des variations périodiques de réluctance définissant, pour le rotor, 2n positions stables. Moteurs électromagnétiques.Electricity. Electromagnetic stepping motor comprising a stator made of soft ferro-magnetic material having two coplanar parts nested one in the other and separated by a sinuous air gap having 2n angularly equidistant radial segments, and a rotor consisting of a flat disc provided with n teeth magnetized axially in the same direction or 2n teeth magnetized axially in the alternating direction, located opposite the radial segments of the stator, characterized in that it comprises a fixed annular part surrounding the rotor and which has internal teeth located substantially in the plane of the rotor so as to present, vis-à-vis the latter, periodic variations in reluctance defining, for the rotor, 2n stable positions. Electromagnetic motors.
