Abstract
(DE)
In einer elektrischen Maschine (1) werden die Dauermagnete (31) eines Rotors (3) der elektrischen Maschine (1) von Spulen (32) umschlossen. Die Spulen (32) können, insbesondere unabhängig voneinander, je nach Erfordernissen der elektrischen Maschine (1), bestromt werden. Insbesondere ist so eine Flussreduzierung des Rotors (3) im Feldschwächbereich möglich, es kann der Fluss im Rotor (3) auch für eine Umschaltung zwischen Wicklungsabschnitten der elektrischen Maschine (1) reduziert werden. Die Spulen (32) können außerdem zur Ermittlung einer Rotorlage verwendet werden.
(EN)
The invention relates to an electric machine (1), in which the permanent magnets (31) of a rotor (3) of the electric machine (1) are enclosed by coils (32). The coils (32) can be energized, in particular independently of one another, depending on the requirements of the electric machine (1). In particular, a flux reduction of the rotor in the field weakening range is thus possible; the flux in the rotor can also be reduced for a changeover between winding sections of the electric machine (1). The coils (32) can additionally be used to determine a rotor position.
(FR)
L'invention concerne une machine électrique (1) dans laquelle les aimants permanents (31) d'un rotor (3) de la machine électrique (1) sont entourés de bobines (32). Les bobines (32) peuvent, notamment indépendamment les unes des autres, être alimentées en courant selon les exigences de la machine électrique (1). Une réduction du flux du rotor (3) est notamment possible dans la plage d’affaiblissement du champ. Le flux dans le rotor (3) peut également être réduit pour une commutation entre des parties d'enroulement de la machine électrique (1). Les bobines (32) peuvent en outre être utilisées pour la détermination d'une position de rotor.
