REVERSIBLE DRIVE CIRCUIT FOR A BRUSHLESS DIRECT CURRENT MOTOR
Реферат: A.MOTEUR A COURANT CONTINU SANS BALAI A CIRCUIT D'ENTRAINEMENT REVERSIBLE. B.MOTEUR CARACTERISE EN CE QUE LE CIRCUIT T, T QUI FORME LE SIGNAL DE COMMUTATION SE COMPOSE D'UN TRANSISTOR DE TYPE NPN ET D'UN TRANSISTOR DE TYPE PNP, FOURNISSANT LE PREMIER SIGNAL DE COMMUTATION SELECTIVEMENT DE L'UN DES TRANSISTORS NPN ET PNP VERS LE PREMIER ELEMENT DE COMMUTATION T, UN MOYEN DE SELECTION 11 ETANT COUPLE AUX CIRCUITS T, T POUR METTRE EN OEUVRE L'UN DES TRANSISTORS NPN OU PNP EN FONCTION DU SIGNAL DE COMMANDE D'INVERSION. A. BRUSHLESS DC MOTOR WITH REVERSIBLE DRIVE CIRCUIT. B. MOTOR CHARACTERIZED IN THAT THE CIRCUIT T, T WHICH FORMED THE SWITCHING SIGNAL CONSISTS OF AN NPN TYPE TRANSISTOR AND A PNP TYPE TRANSISTOR, PROVIDING THE FIRST SWITCHING SIGNAL SELECTIVELY FROM ONE OF THE NPN TRANSISTORS AND PNP TOWARDS THE FIRST T SWITCHING ELEMENT, A SELECTION MEANS 11 BEING COUPLED TO THE T, T CIRCUITS TO IMPLEMENT ONE OF THE NPN OR PNP TRANSISTORS AS A FUNCTION OF THE REVERSE COMMAND SIGNAL.
