Abstract

Circuits d'excitation alimentant les enroulements d'un moteur pas à pas. Les circuits alimentant chaque enroulement en comprennent un premier de faible puissance comportant une alimentation stabilisée et produisant une tension sensiblement constante. Un second circuit de puissance élevée comprend un transistor à montage à charge d'émetteur à la base duquel est appliquée la tension constante. Le second circuit comporte une alimentation non stabilisée dont la tension peut varier considérablement. Ce pendant, ce second circuit transmet une impulsion de courant constante à l'enroulement correspondant du moteur même lorsque la tension de l'alimentation non stabilisée varie beaucoup. Application aux mécanismes de positionnement des têtes de lecture ou d'inscription dans la mémoire à disques d'un appareil de traitement des données.Excitation circuits supplying the windings of a stepping motor. The circuits supplying each winding include a first of low power comprising a stabilized power supply and producing a substantially constant voltage. A second high power circuit includes an emitter load circuit transistor to the base of which the constant voltage is applied. The second circuit has an unstabilized power supply, the voltage of which can vary considerably. However, this second circuit transmits a constant current pulse to the corresponding motor winding even when the voltage of the unstabilized power supply varies a lot. Application to mechanisms for positioning read or writing heads in the disk memory of a data processing apparatus.
