Abstract

Appareil d'enregistrement et/ou de lecture comportant un entraînement direct pour un arbre relié coaxialement au rotor d'un moteur et muni d'au moins deux paliers, dont l'un est disposé entre l'arbre et l'appareil et l'autre entre l'arbre et le stator du moteur, et un dispositif de sécurité qui s'oppose à la rotation du stator et qui est prévu entre l'appareil et le stator du moteur. Ce stator du moteur est monté flottant sur l'arbre. Application : enregistrement et lecture d'informations sur des bandes magnétiques.Recording and / or reading apparatus comprising a direct drive for a shaft connected coaxially to the rotor of a motor and provided with at least two bearings, one of which is arranged between the shaft and the apparatus and the another between the shaft and the stator of the motor, and a safety device which opposes the rotation of the stator and which is provided between the apparatus and the stator of the motor. This motor stator is mounted floating on the shaft. Application: recording and reading of information on magnetic tapes.
