Abstract

Moteur pas à pas. Pour que le moteur accélère rapidement de l'arrêt à la vitesse de fonctionnement voulue et qu'il tourne en continu avec un minimum d'excursion de vitesse, les signaux d'entrée 14 d'amplificateurs A à D) qui commandent les enroulements 20 de phase du moteur sont interrompus périodiquement. Le signal d'interruption périodique 73 dépend de la vitesse détectée par un disque optique 34 qui intercepte un faisceau de lumière envoyé par une source 36 à un photodétecteur. Les impulsions d'horloge qui sont émises entre les signaux produits par le disque sont comptées et le facteur d'utilisation du signal d'interruption périodique est modifié en fonction de leur nombre de manière à régler le couple du moteur. Application aux imprimantes à matrice de fils.Step-by-step engine. In order for the motor to accelerate rapidly from standstill to the desired operating speed and to run continuously with a minimum of speed deviation, the input signals 14 of amplifiers A to D) which control the windings 20 phase of the motor are interrupted periodically. The periodic interrupt signal 73 depends on the speed detected by an optical disc 34 which intercepts a beam of light sent by a source 36 to a photodetector. The clock pulses which are emitted between the signals produced by the disk are counted and the duty cycle of the periodic interrupt signal is changed according to their number so as to adjust the torque of the motor. Application to wire matrix printers.
