Abstract
A method for operating an electric motor, the electric motor comprising at least one first stator with at least three coils and a rotor with at least two magnets, the first stator and the rotor being adjacently arranged in an axial direction, and the coils being adjacently arranged in a peripheral direction. The electric motor is operated at least in the following two states: a) in a first state, the coils are operated by respectively different phases of a three-phase current, and the rotor is rotated about an axis of rotation; and b) in a second state, the coils are operated by an equal-phase alternating current.
