Abstract
(DE)
Die Erfindung betrifft einen Elektromotor, umfassend einen Stator (1) und einen Rotor (2), wobei der Rotor (2) ummagnetisierbare Permanentmagnete (3) aufweist, wobei der Stator (1) in n Teilbereiche (4) über dessen Umfang unterteilt ist, um einzelne Teilbereiche (4) separat voneinander oder in Kombination miteinander über eine Vielzahl von Antriebselementen (5) anzusteuern. Die Erfindung betrifft auch ein Verfahren zum Antreiben eines Elektromotors, wobei die n Teilbereiche (4) des Stators (1), welche über dessen Umfang unterteilt sind, separat voneinander oder in Kombination miteinander über eine Vielzahl an Antriebselementen (5) angesteuert werden.
(EN)
The invention relates to an electric motor, comprising a stator (1) and a rotor (2), wherein: the rotor (2) has permanent magnets (3) capable of magnetic reversal; the stator (1) is divided into n portions (4) over the circumference of the stator in order to control individual portions (4) separately from one another or in combination with one another by means of a plurality of drive elements (5). The invention further relates to a method for driving an electric motor, wherein the n portions (4) of the stator (1), which are divided over the circumference of the stator, are controlled separately from one another or in combination with one another by means of a plurality of drive elements (5).
(FR)
La présente invention concerne un moteur électrique comportant un stator (1) et un rotor (2). Le rotor (2) comprend des aimants permanents à aimantation non inversible (3) et le stator (1) est divisé en n sous-secteurs (4) sur sa circonférence afin de commander des sous-secteurs individuels (4) de manière séparée les uns des autres ou de manière combinée entre eux par le biais d’une pluralité d’éléments d’entraînement (5). La présente invention concerne également un procédé d’entraînement d’un moteur électrique, les n sous-secteurs (4) du stator (1), qui sont répartis sur sa circonférence, étant commandés de manière séparée les uns des autres ou de manière combinée entre eux par le biais d’une pluralité d’éléments d’entraînement (5).
