Title

(EN) CIRCUIT FOR DETERMINING THE SPEED OF A COMMUTATOR MOTOR
(FR) CIRCUIT POUR LA DETERMINATION DE LA VITESSE D'UN MOTEUR ELECTRIQUE A COLLECTEUR
Abstract
(DE)
Es wird eine Schaltungsanordnung zur Bestimmung der Drehzahl eines Kommutatorelektromotors beschrieben. Diese Schaltungsanordnung baut auf hochfrequenten Störungen im Motorstrom bzw. in der Motorklemmspannung auf, die auf den Funkenabriß zwischen Bürste und Kommutator zurückzuführen sind.
(EN)
A circuit for determining the speed of a commutator motor is disclosed. The circuit in question makes use of high-frequency interference occurring in the motor current or in voltage across the motor terminals and caused by break sparks between the brush and commutator.
(FR)
L'invention concerne un circuit servant à déterminer la vitesse d'un moteur à commutateur. Le circuit présenté utilise les interférences à haute fréquence qui se produisent dans le courant du moteur ou dans la tension aux bornes du moteur et sont dues à des étincelles à rupture entre le balai et le collecteur.
