Abstract
An electric machine includes an armature which has a permanent-magnetic excitation part of the machine and a stator which has an induction part of the machine. The induction part includes a first and a second region, each region equipped with current conductors. The armature and the stator are movable relative to each other. The machine includes an electronic commutator which has electronic components. An adjustment to purposefully change a voltage induced in the induction part during operation of the machine, by adjustment of the relative phase of the voltages induced in the two regions of the induction part is achievable due to the first region of the induction part being physically adjustable relative to the second region of the induction part in the direction of relative movement of the armature and the stator. In addition, a sensor is provided in the second region for detecting the instantaneous relative position of the armature and the stator.
