Title
(DE) MEHRMOTORENUMRICHTER
(EN) MULTI-MOTOR CONVERTER
(FR) CONVERTISSEUR MULTI-MOTEUR
Abstract
(DE)
Die Erfindung betrifft ein Regelsystem (1) umfassend einen Mehrmotorenumrichter (PWR) zum geregelten Parallelbetrieb einer Anzahl von n EC-Motoren (M1,..., Mn), deren jeweilige Rotorlage jeweils sensorlos erfasst wird und vom gemeinsamen Umrichter angesteuert wird.
(EN)
The invention relates to a control system (1) comprising a multi-motor converter (PWR) for the closed-loop control of a number of n EC motors (M1, ..., Mn) operated in parallel, the rotor position of each motor being detected without a sensor and being controlled by the converter they share.
(FR)
L'invention concerne un système de régulation (1) comprenant un convertisseur multi-moteur (PWR) pour un fonctionnement en parallèle régulé d'un certain nombre de n moteurs EC (M1,..., Mn), dont la position de rotor respective est détectée sans capteur et est pilotée par le convertisseur commun.
