Abstract
A variable-speed rotating electric machine includes at least two armatures having respective armature coils for multiple phases, and a rotor having permanent magnets. The armatures are arranged concentrically with each other in such a manner that electrical angular positions of the individual armatures can be relatively varied in a circumferential direction. The armature coils of each phase are series-connected and the rotor is arranged concentrically with the armatures on the inside thereof.
