Abstract

A rotor for an electrical machine includes a rotor body and an axis of revolution which extends in an axial direction and about which the rotor body is rotatable. The rotor further includes an outer casing surface which delimits the rotor body, at least one pole arrangement, and a movement mechanism for the at least one pole arrangement. The movement mechanism is designed such that the at least one pole arrangement is movable about a rotation axis which is oriented substantially parallel to the axis of revolution of the rotor. The at least one pole arrangement is also movable about the rotation axis in addition to rotation about the axis of revolution of the rotor.
