Abstract
(DE)
Die Erfindung betrifft eine elektrische Maschine, enthaltend einen Rotor und einen Stator, wobei in der Umfangsfläche des Rotors und/oder des Stators zumindest zwei Ausnehmungen angeordnet sind, welche eine Störung des magnestischen Flusses im Rotor und/oder im Stator bewirken, wobei die Ausnehmungen entlang des Umfangs des Rotors und/oder des Stators unregelmässig verteilt sind.
(EN)
The invention relates to an electric machine containing a rotor and a stator, wherein at least two recesses are arranged in the circumferential surface of the rotor and/or the stator, wherein said recesses effect a disturbance of the magnetic flux in the rotor and/or in the stator, wherein the recesses are irregularly distributed along the circumference of the rotor and/or the stator.
(FR)
L'invention concerne un moteur électrique comportant un rotor et un stator. La surface périphérique du rotor et/ou du stator comporte au moins deux évidements provoquant une perturbation du flux magnétique dans le rotor et/ou dans le stator, les évidements étant répartis de façon irrégulière sur la périphérie du rotor et/ou du stator.
