Title (DE) ANTRIEB, AUFWEISEND EINEN SYNCHRONMOTOR UND EINEN UMRICHTER
(EN) DRIVE HAVING A SYNCHRONOUS MOTOR AND A CONVERTER
(FR) ENTRAÎNEMENT PRÉSENTANT UN MOTEUR SYNCHRONE ET UN CONVERTISSEUR
Abstract:
(DE) Antrieb, aufweisend einen Synchronmotor und einen Umrichter, wobei aus dem wechselspannungsseitigen Anschluss des Wechselrichters die Motorphasen des Synchronmotors, insbesondere also die drei Versorgungsanschlüsse der Drehfeldwicklung des Stators des Synchronmotors, versorgbar sind, wobei insbesondere bei generatorisch betriebenem Synchronmotor, mittels eines steuerbaren Schalters die dreiphasige Motorspannung, insbesondere die drei Motorphasen, des Synchronmotors über jeweilige erste Widerstände einem Sternpunkt zuführbar ist, insbesondere kurzschließbar ist, und/oder wobei insbesondere bei generatorisch betriebenem Synchronmotor, mittels eines steuerbaren Schalters jede Motorphase mit einem jeweiligen ersten Anschluss eines jeweiligen ersten Widerstands verbunden ist und die jeweiligen zweiten Anschlüsse der ersten Widerstände miteinander verbindbar ist, insbesondere als Sternpunkt.
(EN) Drive having a synchronous motor and a converter, wherein the motor phases of the synchronous motor, that is to say in particular the three supply connections of the rotating field winding of the stator of the synchronous motor, can be supplied with power from the AC voltage-side connection of the inverter, wherein, in particular when the synchronous motor is operated as a generator, the three-phase motor voltage, in particular the three motor phases, of the synchronous motor can be supplied to a star point, in particular can be short-circuited, via respective first resistors by means of a controllable switch, and/or wherein, in particular when the synchronous motor is operated as a generator, each motor phase is connected to a respective first connection of a respective first resistor by means of a controllable switch, and the respective second connections of the first resistors can be connected to one another, in particular in the form of a star point.
(FR) L’invention concerne un entraînement présentant un moteur synchrone et un convertisseur, les phases du moteur synchrone, donc en particulier les trois raccordements d’alimentation de l’enroulement à champ tournant du stator du moteur synchrone, pouvant être alimentées à partir du raccordement côté tension alternative de l’onduleur. En particulier dans le cas d’un moteur synchrone entraîné par un générateur, la tension triphasée du moteur, en particulier les trois phases du moteur synchrone, peut être respectivement amenée à un point neutre, en particulier court-circuitée, par l’intermédiaire de premières résistances respectives et/ou, en particulier dans le cas d’un moteur synchrone entraîné par un générateur, chaque phase du moteur est connectée au moyen d’un commutateur commandable à respectivement un raccordement d’une première résistance concernée et les seconds raccordements concernés des premières résistances peuvent être connectés les uns aux autres, en particulier en tant que point neutre.
