Abstract

La présente invention se rapporte aux moteurs électriques à vibrations. Un capteur de vitesse de rotation du rotor 1 est réalisé sous forme d'un système magnétique comportant un aimant 6, un concentrateur 13 de vibrations de torsion, et un circuit magnétique. Une première partie dudit circuit magnétique, mobile, est associée rigidement au rotor 1 et présente des fentes 3 jouant le rôle de repère du rotor 1. La seconde partie 10, séparée de la première par un entrefer 8, est immobile, entoure l'aimant 6 et possède des fentes 11 identiques aux fentes 3. Application : machines pour l'enregistrement et la reproduction de l'information audio.The present invention relates to electric vibration motors. A rotor speed sensor 1 is produced in the form of a magnetic system comprising a magnet 6, a torsional vibration concentrator 13, and a magnetic circuit. A first part of said magnetic circuit, mobile, is rigidly associated with the rotor 1 and has slots 3 acting as a marker for the rotor 1. The second part 10, separated from the first by an air gap 8, is stationary, surrounds the magnet 6 and has slots 11 identical to slots 3. Application: machines for recording and reproducing audio information.
