Abstract

The electrical motor includes a stator and a rotor configured to be rotated about an axis wherein the rotor includes at least three rotor subsegments, wherein a first and second rotor subsegment can be turned relative to one another about the axis in response to a rotation speed range being above a predetermined threshold value of a rotation speed of the electrical machine.
