Abstract

L'invention concerne un circuit rotatif avant-arrière pour moteur à courant continu sans balais, qui comprend une puce intelligente d'alimentation du moteur (IC1), une pluralité d'éléments de Hall et une carte de circuits imprimés (1) sur laquelle sont montés la puce intelligente d'alimentation du moteur (IC1) et une pluralité d'éléments de Hall. Deux ensembles de positions de montage des éléments de Hall sont réservés sur la carte de circuits imprimés (1). Lorsqu'une pluralité d'éléments de Hall est insérée dans le premier ensemble de positions de montage des éléments de Hall (11), le courant circule des premières broches des éléments de Hall aux troisièmes broches et les deuxièmes et quatrièmes broches des éléments de Hall sont connectées à la puce intelligente d'alimentation du moteur (IC1), si bien que le moteur est commandé par la puce intelligente d'alimentation du moteur (IC1) pour tourner normalement. Lorsqu'une pluralité d'éléments de Hall est insérée dans le second ensemble de positions de montage des éléments de Hall (12), le courant circule des troisièmes broches des éléments de Hall aux premières broches, et les deuxièmes et quatrièmes broches des éléments de Hall sont connectées à la puce intelligente d'alimentation du moteur (IC1), si bien que le moteur est commandé par la puce intelligente d'alimentation du moteur (IC1) et tourne en sens inverse. Le circuit offre les avantages d'une structure simple, d'un faible coût de fabrication et d'une grande facilité de mise en œuvre.
