Abstract
An electric motor is proposed comprising a stator and a rotor, wherein the electric motor is an axial-flux motor, the rotor has a rotational axis and is rotationally arranged relative to the stator. The rotor comprises a plurality of permanent magnets, a magnet holder, and a motor shaft. The magnet holder supports the magnets and is fixed to the motor shaft. The magnet holder has an varying axial width, and the axial width of the magnet holder is greater at the motor shaft than at the magnets.
